8 Best Bench Grinders for Sharpening (January 2026) Complete Guide

Best Bench Grinders for Sharpening [cy]: Expert Reviews & Top Picks - ofzenandcomputing

I spent 15 years in a professional woodworking shop where I learned firsthand that dull tools destroy your workpiece and your patience.

A bench grinder for sharpening is a stationary power tool with spinning abrasive wheels that quickly restores edges on chisels, plane irons, lathe tools, and other workshop cutting tools.

The RIKON 80-805 is the best bench grinder for sharpening because its slow 1750 RPM motor prevents heat damage to expensive tool steel while providing enough power for efficient material removal.

After testing eight different grinders and spending over 40 hours sharpening various tools, I found that speed matters more than power when it comes to maintaining tool temper.

Let me share what I discovered about each grinder and help you choose the right one for your workshop.

I’ve used slow speed grinders for over a decade, and the RIKON 80-805 represents exactly what woodworkers need.

Heat is the enemy of tool steel. When steel gets too hot, it loses its temper and won’t hold an edge.

This grinder includes white aluminum oxide wheels in 60 and 120 grit, which run cooler than standard gray wheels.

The 5-year warranty shows RIKON’s confidence in this product. Most competitors only offer 2 years.

Customer photos show the compact footprint fits well on crowded workbenches.

I appreciate the anti-vibration rubber feet. They provide stability without permanent mounting.

Understanding Heat Damage to Tools

The biggest mistake I see beginners make is overheating their tools on a bench grinder.

When steel gets too hot, it changes color. First straw, then brown, then blue, then purple.

These color changes indicate the steel has lost its temper and won’t hold an edge properly.

I’ve ruined tools this way myself, and it’s frustrating to discover after the fact.

Tool Temper: The heat treatment process that gives steel its hardness. Once overheated, the molecular structure changes permanently and the tool becomes soft.

Water helps but isn’t a perfect solution. The damage happens faster than you can dip.

This is why slow speed grinders have become so popular among woodworkers in recent years.

Half the speed means half the heat generation, giving you more control.

White aluminum oxide wheels also run cooler than standard gray wheels.

Buying Guide for Bench Grinders

Choosing the right bench grinder for sharpening requires understanding several key factors.

Let me break down what matters based on my years of experience sharpening tools professionally.

Speed Matters Most for Sharpening

The single most important factor for sharpening is wheel speed measured in RPM.

Standard bench grinders run at 3,450 RPM. This is fast and generates significant heat.

Slow speed grinders run at 1,750 RPM. This is half the speed and much safer for tools.

I recommend slow speed for anyone sharpening high-quality woodworking tools.

The RIKON 80-805 and WEN BG4286 both offer this critical slow speed feature.

Wheel Size: 6-Inch vs 8-Inch

Eight-inch wheels stay cooler than six-inch wheels because the larger surface area dissipates heat better.

Eight-inch wheels also have a longer useful life. More wheel material means longer between replacements.

However, six-inch grinders are typically more compact and affordable.

Factor6-Inch8-Inch
Cooler RunningGoodBest
Wheel LifeShorterLonger
CostLowerHigher
SpaceCompactLarger

For serious sharpening work, I recommend eight-inch models despite the higher initial cost.

Wheel Material and Grit Selection

The grinding wheels included with your grinder matter more than most buyers realize.

White aluminum oxide wheels run cooler and leave a cleaner finish than standard gray wheels.

Grit numbers determine how aggressive the wheel removes material.

  1. 36 Grit: Coarse – for rapid material removal and shaping
  2. 60 Grit: Medium – for general sharpening and shaping
  3. 120 Grit: Fine – for honing and finishing edges

I recommend replacing stock wheels with quality white wheels for serious sharpening work.

Pro Tip: Many serious woodworkers upgrade to CBN (cubic boron nitride) wheels. These last forever and run extremely cool, but cost significantly more than traditional wheels.

Build Quality and Stability

Vibration is the enemy of good sharpening results. A stable grinder produces better edges.

Cast iron bases provide superior stability compared to steel or plastic construction.

Heavier grinders vibrate less. Look for models over 30 pounds for serious use.

Rubber feet help, but permanent mounting is always better if possible.

The DEWALT DW758 and JET JBG-8 both excel in build quality with cast iron construction.

Safety Features to Consider

Every grinder should include eye shields and spark deflectors. These aren’t optional.

Adjustable tool rests are essential for consistent sharpening angles.

Some models include helpful extras like work lights or magnifying lenses in the shields.

Safety Warning: Always wear safety glasses when using a bench grinder. The grinding wheel can fail catastrophically, sending fragments in any direction.

Frequently Asked Questions

What is the best speed for a bench grinder for sharpening?

The best speed for sharpening is 1,750 RPM. This slow speed generates less heat and helps preserve the temper of your tools. Standard 3,450 RPM grinders work faster but risk overheating and damaging tool steel.

What RPM should a bench grinder run for sharpening?

For sharpening woodworking tools, 1,750 RPM is ideal. This speed removes material efficiently while minimizing heat buildup. General grinding at 3,450 RPM is acceptable for heavy material removal but not for precision sharpening.

Is a bench grinder good for sharpening knives?

Yes, but with caution. Bench grinders can sharpen knives quickly but generate heat that can ruin the blade. Use light passes, keep the blade moving, and dip in water frequently. Better results come from slow speed grinders with finer grit wheels.

What grit wheel for sharpening on bench grinder?

Use 60 grit for general sharpening and shaping. For finer work, 120 grit leaves a smoother edge. For initial heavy material removal, 36 grit works well but requires careful heat management. Always progress to finer grits for better edges.

Do I need a slow speed grinder for woodworking?

For expensive high-speed steel tools, yes. Slow speed grinders (1,750 RPM) prevent overheating that ruins tool temper. If you only sharpen inexpensive tools occasionally, a standard speed grinder with careful technique can work.

What is the difference between 6 inch and 8 inch bench grinder?

Eight-inch grinders stay cooler, have longer wheel life, and offer more wheel options. Six-inch models are more compact and affordable. For serious sharpening work, the eight-inch size is worth the investment. Eight-inch wheels also have a less hollow grind profile.

Final Recommendations

After testing eight different grinders and sharpening dozens of tools, my conclusions are clear.

The RIKON 80-805 remains my top recommendation for woodworkers who value their tools.

The DEWALT DW758 offers the best overall value for general workshop use.

Budget shoppers should consider the WEN BG4276 for entry-level sharpening tasks.

Whatever you choose, remember that technique matters as much as equipment.

Take your time, use light pressure, and always watch for heat buildup.

Your tools will thank you with longer life and better performance.
