List of The Bench Grinders

The 8 Best Bench Grinders for 2021

Its single-speed strong 2.1 AMP motor can spin the wheel at 3450 RPM with no load, which is suitable for removing dust from metal as well as deburring rough edges.

This top-notch 6-inch bench grinder comes with two wheels, both measuring 6 inches in diameter and have a width of 3/4 of an inch.

One of them is a coarse 36-grit wheel that enables you to smoothen any rough parts or remove excess material while the other is a fine 60-grit wheel that suits almost all grinding tasks.

Moreover, the installation and startup of this unit are easy, so you can start working as soon as you unbox it with no frustration.

As for the safety measures, the WEN 4276 comes with a clear adjustable eye shield that protects you from any flying fragments or scraps.

However, that shouldn’t stop you from wearing safety goggles to reduce the risk of injury. And in case you want to replace your buffing wheel, you can easily remove the eye guard.

The WEN 4276 comes with a work light that provides you with adequate visibility. The overhead lamp is also adjustable so that you can direct the light and the point where you are working.

A downside is although the power of this unit is not that high, it still produces considerable noise.

With a cast iron motor housing base, there will be no wobbling and the unit will remain sturdy, even at fast-spinning speeds.

Finally, the WEN 4276 grinding machine comes with an adjustable tool rest with a drill bit that gives you the support needed when sharpening your bits and blades.

What Are the Uses of a Bench Grinder?

A bench grinder is a system of two wheels that are used at a very high speed to finish different jobs of grinding applications. It can be used with wood or metal depending on the strength of the wheel and how fast it spins with a variable speed bench grinder.

You can use your bench grinder to shape or buff wood if it’s a slow speed grinder wheel.

If it’s a fast speed grinder wheel, you can use it to make cuts through wooden pieces or metal ones.

Moreover, you can use your bench grinder to sharpen chisels and other sharp metal tools around your garage or workshop.

What Features to Look for When Shopping for a Bench Grinder?

If you’re not sure what features to look for when you’re buying a bench grinder, here are the things that make a difference in terms of the performance of your unit.

Size

The size of your bench grinder has a lot to do with how powerful it will be and consequently what work you’ll be able to do with it.

Larger grinders are more suitable for sawing, making cuts, and filing. On the other hand, smaller ones like an angle grinder fit more delicate grinding operations such as shaping metal.

Motor

Motors with higher horsepower will be more efficient at cutting tougher and hardened metals. So if you’re going to do that, go for a 1 HP motor.

½ HP would be good enough for doing medium-duty or light-duty jobs.

Speed

The speed of a bench grinder is measured in RPM (Revolutions per Minute), and it depends on the horsepower of the motor.

a grinder wheel with a Faster speeds such as 3000 RPM allow you to cut through hardened steel and stronger metals.

You can save some money by buying a 1750 RPM slow speed bench grinder if you’re going to be working with wood or softer woods.

Grinding Wheel

Size

Professional work requires around 8-inch wheels that work at slower speeds but don’t need much maintenance.

For faster operation and versatility, you should go for a 6-inch wheel, although these require frequent changes.

Grit

There are three major grit abrasive wheel sizes: 100, 60, and 30. The coarse 30-grit wheels are suitable for general sharpening. But if you want smooth results and accurate output, you should go for fine wheels of 60 or 100 grits.

Color

The color of the wheel can help you identify the kind of job you can do with it.

Brown wheels are suitable for heavy fettling and trimming, grey ones for every day grinding, white ones for sharpening, and green ones for fine grinding. The latter ones work well with blades and a drill bit as well as anything made from silicon carbide such as carbide tools.

Safety Features

You should make sure that the bench grinder that you get complies to the safety standards of the industry with enough safety precautions.

Spark Deflectors

Wheel guards should cover 75% of the buffing wheel and leave only 25% exposed through which you can work.

This is to protect your face and eyes from any flying fragments that result from grinding.

Eye Shields

Eye shields are transparent plastic covers found above the opening through which the grinding wheel touches your workpiece.

These also help keep any scraps from flying off and hurting your eyes.

Dust Exhaustion

Dust exhaustion systems, vents, or ports all help in getting rid of the debris and dust that result from the grinding process and which can cause considerable harm if inhaled. It also maintains visibility so you can see what you’re working on.

Cooling

If your grinder isn’t a “wet grinding machine,” you’ll need a bucket or a pot with water to dip your workpiece in to keep them cool.

Wet grinding machines are grinders that have built-in cooling systems to prevent them from overheating.

FAQs About Your New Bench Grinder

Do I need a variable speed bench grinder?

With a simple answer no. Although variable speed grinders might be quite handy. you can still do your tasks of grinding applications without one.

Keeping in mind that single-motor speed grinders are just as efficient as variable-motor speed grinders. because how much pressure you apply to the grinding wheel is what makes the difference in the performance.

It’s worth noting that having a variable speed grinder allows you to sharpen woodworking cutting tools at a low speed. Alternatively, a high motor speed can be used to grind down a bolt end or remove rust spots from car parts.

Should I get a 6-inch or 8 inch bench grinder?

Bench grinders with an 8-inch diameter are designed for professionals. While most people searching for adaptability and multifunctional usage. A 6-inch grinder will serve them well.

An 8 inch bench grinder, on the other hand, will serve you well. If you are performing a complicated task of grinding applications.

If you’re a DIYer who’s never used a bench grinder before, a 6-inch bench grinder model should be quite powerful enough. to polish, sharpen, and repair a variety of gears and utensils.

One disadvantage of having an 8 inch bench grinder wheel is that it is slower. but requires fewer wheel changes. There is less maintenance required as compared to 6-inch bench grinders.

While an 8-inch bench grinder costs more you’ll save money in the long term. Because you will need to replace the wheels more regularly than the 6-inch grinders

Can a bench grinder be used on wood?

Yes, you certainly can. A bench grinder may be used to reshape or polish any wood product. However, it will involve the replacement of the grinding wheel.

While bench grinders are most used for polishing, forming, and buffing metal. they may also be used on wood.

Keep in mind that your bench grinder can sand, carve, shape, buff, smooth. or polish a wide range of woods with the proper wheel.

Bench grinders, on the other hand, are best utilized on hard materials and should not be used on very soft woods.

Final Thoughts

While all the grinders I’ve mentioned are great, I’d say the dewalt dw758 bench grinder is the best overall. Not only is it affordable, but it’s also versatile, fast, and has ample power to finish almost any job.

If you’re looking for something that’ll cut through tough materials without heating up, the WEN 4286 is a perfect candidate -although it’s a little slow in its operation.

For a budget choice, go for the dewalt dw756 bench grinder as it’s very affordable but still provides you with good performance and speed. Finally, I think the Craftsman 9-21154 is a good choice for someone who’s looking for the ultimate versatility as this unit comes with variable speeds -a feature that none of the others have.
