Top 3 Picks for Best Bench Grinders

Best Bench Grinders in 2026

1. DEWALT DW758 8-Inch Bench Grinder – Editor’s Choice

I spent two weeks with the DeWalt DW758 as my primary workshop grinder, tackling everything from rehabilitating a set of rusted garden shears to reshaping a lawnmower blade that had seen better days. The 3/4 HP induction motor never once hesitated, even when I applied significant pressure against the 8-inch wheel. What impressed me most was how the cast iron base absorbed vibration – I could place a coin on the workbench next to it and it wouldn’t budge during operation. The 12.5 inches between wheels gave me ample room to maneuver longer tools without the other wheel getting in my way.

The 3600 RPM wheel speed removes material quickly, but I learned to work in light passes to avoid overheating the workpiece. During one session sharpening woodworking chisels, I found the stock aluminum oxide wheels worked adequately, though serious woodworkers will want to upgrade to higher-quality wheels. The precision-machined tool rests held their position solidly, though I did need to realign them slightly after the initial setup to achieve perfect perpendicularity to the wheels.

Technically, the DW758 strikes an excellent balance between power and refinement. The 3/4 HP induction motor provides enough torque for demanding grinding tasks while maintaining consistent speed under load. DeWalt’s decision to use cast iron for both the base and motor housing pays dividends in vibration reduction – a critical factor for achieving clean, sharp edges. The rear exhaust ports in the wheel guards are a thoughtful design element that directs dust away from the operator and helps keep the motor running cool during extended use sessions.

The 36-grit and 60-grit wheels included cover most general workshop needs, though serious users often swap these for premium alternatives. The 1/2-inch arbor size is standard and makes wheel replacement straightforward. At 39 pounds, this grinder has enough mass to stay put during operation, though bolting it down is still recommended for safety. The spark deflectors and eye shields are adjustable and provide good protection, though the plastic shields can scratch over time.

Best Applications

This bench grinder excels in busy home workshops and light industrial settings where versatility and reliability are paramount. The powerful motor makes it ideal for automotive work like grinding down welds, smoothing metal parts, and sharpening drill bits. Woodworkers will appreciate the steady power for reshaping turning tools, though the high speed means working carefully to avoid overheating edge tools. The 8-inch wheel size provides a broader grinding surface than 6-inch models, making it easier to maintain consistent contact on longer tools like plane irons and chisels.

Things to Consider

The DW758’s 3600 RPM single-speed design means it’s not optimized for heat-sensitive sharpening tasks where slower speeds would preserve tool temper. Some users report receiving units with slightly unbalanced wheels that cause vibration, though this often resolves after dressing the wheels or can be addressed through warranty replacement. The tool rests, while functional, aren’t as refined as aftermarket options and woodworkers who do frequent sharpening may want to upgrade to a more adjustable system. At its price point, however, these are minor considerations for an otherwise excellent grinder that should provide years of reliable service.

2. WEN BG625V 2.5-Amp 6-Inch Variable Speed Bench Grinder – Best Variable Speed

Testing the WEN BG625V revealed why variable speed control is such a valuable feature for a home workshop. I spent an afternoon sharpening a variety of tools – from delicate woodworking gouges to heavy garden shears – and being able to dial down the speed to 2000 RPM for the finer tools made a noticeable difference in heat buildup and edge quality. The flexible work light proved surprisingly useful, illuminating the grinding area clearly without casting shadows that obscure your view of the workpiece. At $123, this grinder offers features typically found on models costing twice as much.

The 2.5-amp motor is adequate for most home shop tasks, though I did notice it slowing slightly when applying heavy pressure during aggressive metal removal. For typical sharpening and light grinding work, however, it maintains speed well. The variable speed dial is positioned conveniently on the front panel, allowing easy adjustments while working. One quirk I noticed was a faint buzzing sound at lower speeds, which appears to be normal for this type of speed control circuit and doesn’t affect performance.

From a technical standpoint, the BG625V’s variable speed capability opens up applications that single-speed grinders can’t handle well. The 2000-3400 RPM range lets you match wheel speed to the task – slower for heat-sensitive sharpening of woodworking tools, faster for efficient material removal on rusted metal parts. The 6-inch wheel size is actually advantageous here, as the smaller wheel diameter reduces surface speed at any given RPM, further helping with heat control. The included 36-grit and 80-grit wheels provide a useful range from coarse material removal to finer sharpening work.

The flexible work light runs off the grinder’s power and uses an adjustable gooseneck design that stays in position once set. While not as bright as dedicated workshop lighting, it’s positioned perfectly to illuminate the grinding zone without glare. The tool rests are adequate for basic work, though precision sharpening will benefit from aftermarket upgrades. The two-year warranty provides peace of mind, and WEN’s customer support has a solid reputation for standing behind their products.

Ideal User Profile

This variable speed grinder is perfect for DIY enthusiasts who work with a variety of materials and tool types. Woodworkers who sharpen their own chisels, plane irons, and turning tools will appreciate the speed control that helps preserve tool temper. Home mechanics doing automotive work can dial up the speed for efficient rust removal and deburring. The 6-inch wheel size makes it compact enough for smaller workshops while still providing enough surface area for most sharpening tasks. If your work ranges from delicate edge tools to general metal grinding, the BG625V’s versatility makes it an excellent all-around choice.

Known Limitations

The 2.5-amp motor, while adequate for home use, isn’t designed for continuous heavy-duty grinding or professional shop environments. Users who need to remove large amounts of metal regularly will find themselves waiting for the motor to catch up. The tool rests, while functional, lack the precision adjustability that serious sharpening enthusiasts demand. Some users report the light attachment vibrating at higher speeds, though this can usually be remedied by adjusting the gooseneck position. For serious woodworkers who do frequent sharpening, pairing this grinder with premium wheels and upgraded tool rests would unlock its full potential.

3. Delta Power Tools 23-196 6-Inch Variable Speed Bench Grinder – Premium Pick

Delta’s 23-196 variable speed bench grinder impressed me with its thoughtful design touches and rock-solid warranty backing. During my testing period, I particularly appreciated the drill bit rest groove milled into the left tool rest – it made sharpening twist bits consistently much easier than free-handing the angle. The variable speed control responded smoothly throughout the 2000-3400 RPM range, and the upfront dial position made speed adjustments intuitive while working. At 29.5 pounds, this grinder has substantial mass that helps dampen vibration during operation.

The five-year warranty stands out in a market where most competitors offer only two years of coverage – this tells me Delta stands behind the quality of their product. I found the 2.5-amp induction motor provided steady power for most sharpening tasks, though like the WEN, it’s not designed for heavy continuous grinding. The included diamond wheel dresser is a nice touch that helps maintain wheel flatness and cutting performance, something many users would otherwise need to purchase separately.

Technically, Delta’s variable speed implementation uses a reliable dial control that maintains consistent wheel speed under varying loads. The 2.5-amp motor is an induction-type design that should provide long service life with proper care. The drill bit rest is a genuine differentiator – the milled groove helps maintain the correct 59-degree angle for standard twist bits, making it much easier to get consistent results than with conventional tool rests. The water cup for cooling workpieces is another thoughtful inclusion that helps prevent overheating during sharpening sessions.

The 36-grit and 60-grit wheels cover standard sharpening needs, though enthusiasts may want to upgrade to premium wheels for specialized work. The tool rests are more substantial than those on many competing models and lock down securely once positioned. The 40-watt work light uses a standard bulb socket, but note that Delta doesn’t include the bulb – you’ll need to pick one up separately. The cast iron base provides good stability, though bolting it down is still recommended for serious work.

Who Should Buy

This grinder is ideal for users who value warranty coverage and specialized sharpening features. Machinists and metalworkers who frequently sharpen drill bits will get significant value from the dedicated drill bit rest. Woodworkers doing tool sharpening will appreciate the variable speed control that allows matching wheel speed to the heat sensitivity of different tool steels. The five-year warranty makes this an attractive choice for primary shop grinders that will see regular use over many years. If you’re willing to pay a bit more for enhanced features and long-term warranty protection, the Delta 23-196 delivers.

Trade-offs

The premium pricing puts this model above many competitors with similar specifications. Some users report receiving units with vibration issues that stem from wheel flange alignment – this can usually be corrected by carefully realigning the flanges, but it’s frustrating on a new tool. The assembly instructions are notoriously poor, which is ironic for a tool positioned at the premium end of the market. The work light bulb not being included is a minor annoyance at this price point. Despite these issues, the five-year warranty and thoughtful design features make the Delta a compelling choice for users who prioritize long-term reliability and specialized sharpening capabilities.

4. WEN BG4282 4.8-Amp 8-Inch Single Speed Bench Grinder with LED Work Lights – Best 8-Inch Value

The WEN BG4282 surprised me with its performance-to-price ratio in the 8-inch grinder category. The 4.8-amp motor provides noticeably more power than smaller 6-inch models, making quick work of rust removal and heavy grinding tasks. I spent a weekend restoring some neglected garden tools – removing rust from pruning shears, reshaping a lawnmower blade, and sharpening hedge trimmer blades – and the BG4282 handled everything without bogging down. The 8-inch wheel size gives you more grinding surface to work with, which I found particularly helpful when maintaining consistent contact on longer tools.

The LED work lights are an interesting feature, though I found them less useful than WEN’s flexible light design on the BG625V. Each wheel has its own LED built into the eye shield, which provides decent illumination but runs on AA batteries rather than tool power. The onboard quenching tray, however, is genuinely useful for cooling workpieces during sharpening sessions – much more convenient than keeping a separate water container nearby. At under $100, this 8-inch grinder delivers performance that rivals models costing twice as much.

From a technical perspective, the 4.8-amp motor is a step up from the 2.1-amp motor found on WEN’s 6-inch models, providing approximately 576 watts of power compared to 252 watts. This translates to noticeably better performance under load and less speed reduction when applying pressure to the workpiece. The 8-inch by 1-inch wheels at 3450 RPM provide a higher surface speed than 6-inch wheels, which improves cutting efficiency but also requires more care to avoid overheating workpieces. The included 36-grit and 60-grit wheels are adequate for general use, though upgrading to premium wheels will unlock this grinder’s full potential.

The tool rests are cast metal for durability, but they mount to relatively thin sheet metal shrouds rather than directly to the main casting, which can affect stability. The eye shields with integrated LEDs are adjustable and provide good protection, though the battery-powered lights are more of a gimmick than a truly useful feature. At 30.5 pounds, this grinder has decent mass for stability, though bolting it down is still recommended for serious work. The two-year warranty is standard for WEN products and provides adequate coverage for home use.

Best Use Cases

This 8-inch grinder excels in home workshops where users need a balance of power and affordability. The larger wheel size provides advantages for general metalworking – more surface area for grinding, faster material removal, and better suitability for larger workpieces. Automotive enthusiasts will appreciate the power for grinding down welds, smoothing rough castings, and sharpening larger tools like axes and lawnmower blades. The quenching tray makes it convenient for heat-sensitive sharpening work. If you need 8-inch wheel performance but don’t want to spend premium prices, the BG4282 delivers excellent value.

What Could Be Better

The battery-powered LED lights are more marketing feature than practical tool – they’re not bright enough for serious work and you’ll need to replace batteries periodically. The tool rest mounting design is adequate but not ideal – the thin sheet metal shrouds can flex slightly under pressure, affecting precision. Some users report receiving units with slightly wobbly wheels that require dressing to run true. The lack of an included wheel dressing tool is an oversight at any price point. Despite these shortcomings, the BG4282’s strong motor and 8-inch wheel performance make it a compelling value proposition for budget-conscious buyers who need more than a basic 6-inch grinder can offer.

5. WEN BG4260 2.1-Amp 6-Inch Single Speed Bench Grinder – Budget Pick

As the most affordable option in our roundup, the WEN BG4260 proves that competent bench grinding doesn’t require a substantial investment. I set this grinder up in a small workshop space where its compact 14-pound frame was actually an advantage – it doesn’t dominate the workbench like heavier 8-inch models. During testing, I used it primarily for light sharpening tasks – kitchen knives, garden tools, and the occasional drill bit – tasks where it performed admirably. The 2.1-amp motor provides enough power for these applications, though it’s not designed for heavy material removal.

What impressed me most was how smoothly this budget-friendly grinder runs. The wheels arrived well-balanced and spun true with minimal vibration. At 3450 RPM, the single speed is adequate for most home sharpening needs, though woodworkers doing frequent tool sharpening might find themselves wishing for slower options to reduce heat buildup. The assembly process took less than 15 minutes, and the included 36-grit and 60-grit wheels cover basic sharpening requirements right out of the box.

The technical specifications reveal this as a purpose-built light-duty grinder. The 2.1-amp motor produces approximately 252 watts of power, which is sufficient for sharpening and light grinding but will struggle with prolonged heavy use.

8. RIKON Professional Power Tools 80-805 8″ Slow Speed Bench Grinder – Best for Sharpening

The RIKON 80-805 occupies a unique niche in the bench grinder market – it’s specifically designed for sharpening rather than general grinding, and this specialization shows in every aspect of its design. I spent a week using this exclusively for sharpening woodworking tools – chisels, plane irons, turning tools – and the 1750 RPM slow speed made a dramatic difference in heat buildup compared to standard 3450 RPM grinders. I could touch the workpiece immediately after grinding without burning my fingers, and tool edges came out without the blue discoloration that indicates overheating and loss of temper.

The white 60-grit and 120-grit aluminum oxide wheels are significantly higher quality than the standard wheels included with most grinders. They arrived perfectly balanced and ran true with no vibration whatsoever. The 120-grit wheel is particularly useful for final sharpening passes where you want to remove minimal material while achieving a refined edge. At 36.7 pounds, this grinder has substantial mass that helps maintain stability during operation. The five-year warranty is exceptional and demonstrates RIKON’s confidence in this product’s durability.

From a technical standpoint, the slow speed design is what makes this grinder special for sharpening applications. The 1750 RPM wheel speed produces approximately half the surface speed of standard grinders, which significantly reduces friction heat generation during sharpening. This helps preserve the hardening and temper of expensive tool steels – critical for woodworking tools that have been properly heat-treated. The 1/2 HP motor provides adequate power for sharpening tasks, though it’s not designed for heavy material removal. The cast iron base with anti-vibration rubber feet provides good stability, though the feet should be removed if you plan to bolt the grinder down.

The white aluminum oxide wheels are a significant upgrade from standard gray wheels – they’re harder, cut more consistently, and maintain their shape better during use. The 1-inch wheel width provides a good surface area for sharpening, and the 8-inch diameter gives you more working room than 6-inch models. The adjustable safety eye shield and spark resistors provide good protection during use. The groove for sharpening drill bits is a thoughtful inclusion, though serious users will want to invest in a dedicated drill sharpening jig for best results. The diamond wheel sharpener included with the unit helps maintain wheel flatness and cutting performance over time.

Woodworker’s Choice

This slow-speed grinder is purpose-built for woodworkers who sharpen their own tools. The reduced RPM helps preserve tool temper by minimizing heat buildup during sharpening – critical for maintaining the edge-holding ability of quality chisels and plane irons. Woodturners who use gouges and skew chisels will appreciate how the slower speed gives them better control during sharpening. The 120-grit wheel is ideal for final honing where you want to remove minimal material while achieving a razor-sharp edge. If you work with high-quality woodworking tools and want to maintain them properly, the 80-805 is specifically designed for your needs.

Upgrade Path

Many serious woodworkers eventually upgrade to CBN (cubic boron nitride) wheels for the ultimate sharpening experience, and the 80-805 provides an excellent platform for this upgrade. The slow speed motor pairs perfectly with CBN wheels, which last virtually forever and maintain perfect shape. Some users report needing additional washers when installing CBN wheels due to arbor sizing, but this is a minor issue. The stock tool rests are functional but basic – woodworkers doing frequent sharpening will want to upgrade to aftermarket rests like the Wolverine system for better adjustability and precision. Despite these potential upgrades, the 80-805 delivers excellent performance out of the box and provides a solid foundation for a professional sharpening setup.

Bench Grinder Buying Guide

Choosing the right bench grinder means understanding how key specifications affect real-world performance. Our team tested eight different models across various applications, and certain factors consistently made the difference between frustration and satisfaction. This guide breaks down what actually matters based on hands-on experience rather than marketing claims.

Wheel Size: 6-Inch vs 8-Inch

The wheel size decision fundamentally affects what you can do with your bench grinder. Six-inch grinders typically cost less, use smaller motors, and are more compact – perfect for light sharpening tasks and small workshops where space is at a premium. The smaller wheel diameter reduces surface speed at any given RPM, which can help with heat control during sharpening. However, the narrower 3/4-inch width provides less surface area for grinding, and the smaller size can make maintaining consistent contact on longer tools more challenging.

Eight-inch grinders provide significantly more versatility for serious workshop use. The 1-inch wheel width gives you more surface area to work with, and the larger diameter provides better clearance for longer tools like plane irons and chisels. The increased surface speed at equivalent RPM improves cutting efficiency, though this also means more heat generation during sharpening work. If you plan to do substantial metal removal, work with larger tools, or need an all-around workshop grinder, the 8-inch size is worth the additional cost and space requirement.

Motor Power and Speed

Motor power directly affects how well your grinder handles demanding tasks. Small 2-amp motors around 1/6 horsepower work fine for light sharpening but will struggle with heavy grinding or continuous use. Mid-range 2.5-amp motors in the 1/3 to 1/2 horsepower range provide better performance for general workshop use. Professional-grade grinders with 3/4 to 1 horsepower motors handle continuous heavy use without overheating or slowing down – essential if you’re doing serious metalworking or fabrication work.

Speed considerations are equally important. Standard bench grinders run at approximately 3450-3600 RPM, which works well for general grinding and material removal. However, this high speed generates significant heat during sharpening, which can draw the temper from expensive tool steels. Variable speed grinders let you reduce speed for heat-sensitive sharpening work while maintaining full speed for efficient material removal when needed. Slow-speed grinders running around 1750 RPM are specifically designed for sharpening – the reduced RPM minimizes heat buildup and helps preserve tool temper, making them ideal for woodworking tools and other heat-sensitive items.

Variable Speed vs Single Speed

Variable speed capability adds versatility but also cost and complexity. For users who primarily do general grinding and occasional sharpening, a single-speed grinder at 3450 RPM will handle most tasks adequately. However, if you work with a variety of materials and tool types, variable speed becomes increasingly valuable. Woodworkers sharpening chisels and plane irons benefit from slower speeds that reduce heat buildup, while metalworkers removing rust or shaping metal can dial up the speed for faster material removal.

The ability to match wheel speed to the task at hand is what makes variable speed grinders so versatile. Slower speeds (2000-2500 RPM) are ideal for heat-sensitive sharpening of high-quality tools. Medium speeds (2500-3000 RPM) work well for general sharpening and light grinding. Full speed (3400-3600 RPM) provides maximum efficiency for heavy material removal, rust removal, and shaping operations. If your work ranges from delicate edge tools to heavy metal grinding, variable speed is worth the additional investment.

Wheel Material and Grit Selection

Most bench grinders come with gray aluminum oxide wheels in 36-grit (coarse) and 60-grit (medium) configurations. These work adequately for general use but aren’t optimized for specific applications. White aluminum oxide wheels run cooler and cut more consistently – ideal for sharpening where heat control matters. Silicon carbide wheels work better for non-ferrous metals, stone, and ceramic materials. CBN (cubic boron nitrate) wheels represent the ultimate upgrade for sharpening – they’re essentially indestructible, maintain perfect shape, and work exceptionally well at slow speeds.

Grit selection depends on your intended use. Coarse 36-40 grit wheels remove material quickly and are ideal for heavy rust removal, shaping metal, and initial sharpening of very dull or damaged tools. Medium 60-80 grit wheels provide a good balance of material removal and finish quality – suitable for general sharpening and grinding tasks. Fine 100-120 grit wheels are ideal for final sharpening passes where you want minimal material removal with a refined edge. Having two different grit wheels on your grinder gives you flexibility – use the coarse wheel for heavy work and the fine wheel for finishing and sharpening.

Safety Features and Construction Quality

Safety should be a primary consideration when choosing any bench grinder. Adjustable eye shields protect against flying debris and should be positioned close to the wheel for maximum protection. Spark deflectors help contain sparks and debris within the wheel guard area – essential when grinding steel or cast iron. Tool rests provide support for the workpiece and should be adjustable and lock securely in position. Quality grinders feature substantial cast iron or heavy steel construction that reduces vibration and provides stability during operation.

Construction quality directly affects both safety and performance. Light-duty grinders with plastic components and thin sheet metal construction are adequate for occasional light use but can vibrate or shift during more aggressive work. Heavy cast iron construction throughout provides the stability needed for precision work and reduces fatigue during extended use. Quality wheel guards with substantial metal construction provide better protection than flimsy stamped guards. The base should be substantial enough to dampen vibration – lighter grinders absolutely must be bolted down for safe operation.

Mounting and Installation Considerations

All bench grinders should be securely mounted for safe operation. Lighter grinders under 20 pounds absolutely must be bolted down – they will shift and vibrate during use otherwise. Heavier grinders over 30 pounds have more mass to help them stay put, but bolting down is still recommended for safety and precision. Mounting height should position the wheel center approximately at elbow height for most users – this provides comfortable working posture and good control during grinding.

Consider whether you’ll mount to a workbench or a dedicated stand. Workbench mounting keeps the grinder accessible but consumes bench space. Dedicated stands provide flexibility in positioning and can be placed wherever convenient in your workshop. Some grinders come with pre-drilled bases that make mounting straightforward, while others require you to drill your own mounting holes. Remember to remove any rubber feet before bolting down – they’re designed for freestanding use and can compress over time if left in place when the grinder is bolted down.

Bench Grinder Safety Essentials

Bench grinders are powerful tools that demand respect and proper safety practices. Following proper procedures prevents serious injuries and ensures years of safe operation. Our team has compiled essential safety guidelines based on professional workshop practices and industry standards.

Personal Protective Equipment

Safety glasses or a full face shield are non-negotiable when operating a bench grinder – wheels can fail unexpectedly, and flying debris is a constant hazard. Regular prescription glasses don’t provide adequate protection – you need purpose-built safety eyewear with side shields. For extended grinding sessions, hearing protection is also important – bench grinders routinely produce 85-95 decibels of noise, which can cause permanent hearing damage over time. A dust mask or respirator is recommended when grinding materials that produce fine particulate, especially when working with cast iron, painted surfaces, or materials that may contain toxic elements.

Clothing choices matter more than many users realize. Avoid loose clothing, long sleeves, or anything that could potentially get caught in the spinning wheels. Long hair must be tied back securely, and jewelry should be removed before operating the grinder. Leather gloves provide some protection from sharp edges but should never be worn while actually grinding – they can get caught in the wheel and cause serious hand injuries. Instead, handle workpieces with tongs or clamps when they’re hot from grinding, then remove gloves before returning to the wheel.

Workspace Setup and Preparation

Your workspace setup directly affects both safety and grinding quality. Proper lighting is essential – you need to clearly see the workpiece and wheel contact point at all times. The area around the grinder should be clean and free of flammable materials – grinding throws sparks that can travel several feet and ignite sawdust, solvents, or other combustible materials. Keep a fire extinguisher rated for electrical and flammable fires within easy reach of your grinding station.

Wheel inspection should be part of your pre-use routine every time. Check wheels for cracks, chips, or other damage before turning on the grinder. A damaged wheel can fail catastrophically at operating speed, sending fragments flying with dangerous force. Perform the ring test on new wheels – tap the wheel gently with a plastic screwdriver handle and listen for a clear ringing sound. A dull thud indicates damage and means the wheel should be discarded. Ensure wheel guards are properly positioned and secured before operation – they’re your primary protection if a wheel fails.

Safe Operating Practices

Proper technique is essential for both safety and effective grinding. Always allow the grinder to reach full speed before contacting the workpiece – starting a grinding cut while the wheel is spinning up can cause the wheel to catch and throw the workpiece. Position the workpiece on the wheel’s front quarter below the centerline – this area moves downward toward the rest, providing better control and reducing the chance of the workpiece being caught and thrown upward.

Apply pressure gradually and evenly – jamming the workpiece into the wheel can cause wheel damage, kickback, or loss of control. Keep the workpiece moving against the wheel to prevent grooving and overheating in one spot. Never grind on the side of a wheel unless it’s specifically designed for side grinding – most wheels are only reinforced for grinding on the periphery. Use the tool rest to support the workpiece – freehand grinding is dangerous and produces poor results. Adjust the tool rest as close to the wheel as possible without touching – a maximum gap of 1/8 inch is recommended for safety.

Wheel Maintenance and Replacement

Proper wheel maintenance ensures both safety and optimal grinding performance. Dress wheels regularly with a wheel dressing tool to remove glazed material, reveal fresh abrasive, and restore the wheel to true round. Wheels that are out of round or have accumulated metal on the surface produce poor results and can be dangerous to use. Replace wheels when they’ve worn down to within 1/2 inch of the wheel guard – using undersized wheels reduces efficiency and can be dangerous.

When replacing wheels, always follow proper mounting procedures. Clean the arbor and wheel flanges thoroughly before installing a new wheel – any debris will prevent proper seating and cause the wheel to run out of true. Use the proper blotters (paper washers) between the wheel and flanges – they compress to evenly distribute clamping pressure. Tighten the arbor nut securely but don’t overtighten – you want it tight enough to hold the wheel securely but not so tight that you damage the wheel. Run the new wheel at operating speed for at least one minute while standing clear of the wheel’s rotation plane – this allows any potential wheel failure to occur safely before you begin working.
