The 8 Best Bench Grinders for 2021
1. WEN 4276 – Best lightweight Grinder
The WEN 4276 is a grinder that weighs only 16 pounds. It’s sturdy enough to remain in its place and light enough to give you some portability.
As it measures 14 x 9.8 x 15 inches, the grinder is quite compact and doesn’t take up a lot of room in your workshop.
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 which 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 clear eye guards that protect 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 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 base, there will be no wobbling and the unit will remain sturdy, even at fast-spinning speeds.
Finally, the WEN 4276 comes with an adjustable tool rest that gives you the support needed when sharpening your bits and blades.
- A little noisy
- Expandable functionality with many accessories
- Portable enough
- Wheels are easy to change
- Equipped with a work light to provide visibility
- Durable construction
- 2-year warranty with excellent customer service
- Great bang for your buck
- Only suits DIY-ers but not heavy-duty work
- Wheels must be spinning for the light to switch on
2. DeWalt DW758 -best grinder for sharpening
Running on a powerful 3/4 horsepower motor, it can spin its wheels at a speed of 3600 RPM -the fastest on the list.
What makes it suitable for sharpening is that its wheels measure 8 inches and they come in two varieties: a 36-grit one for faster removal of material and a 60-grit for general grinding projects.
I like the safety and ergonomics that DeWalt integrated into this unit. The wheel guards come with exhaust ports at the back to smoothen the operation of the machine.
Moreover, aluminum tool rests are found against the wheels to keep everything within your reach.
However, I didn’t like the fact that they left out a work light -especially that they’re not expensive to add, but they go a long way in terms of convenience.
And although it is quite compact, it is not portable because it weighs a hefty 39.5 pounds.
But generally the DW758 gives you great value for your money, and I think its operation is sturdy and reliable.
- Powerful motor
- Compact design
- Easy to adjust
- Comes with a long warranty
- Doesn't have a work light
- The wheels can be a little wobbly
3. Rikon Professional Power Tools
The Rikon 80-805 is an excellent choice for anyone looking for an affordable slow speed bench grinder.
Running on a ½ HP motor, it spins its 8-wheels at 1750 RPM. This makes it very effective at sharpening and removing excess material.
Admittedly, it took me some time to adjust to the awkward position of the wheel.
At 36.9 pounds, it’s not the lightest, but it’s pretty compact at 16.4 x 10.8 x 11.2 inches.
To make its operation safe, Rikon equipped their grinder with robust spark deflectors surrounding the wheels as well as separately adjustable eye shields.
Moreover, the cast iron base makes the unit sit sturdily in its position with the help of the rubber feet that also work on reducing vibration and noise.
I liked the extra focus they gave to drill bits as the left-hand tool rest comes with a V-groove, especially for honing them.
Not to mention the diamond wheel dresses that help you maintain your wheel. This may also help with how wobbly the Rikon 80-805 can be.
I’d like to think the 5-year warranty is a good reason to trust in this unit’s durability and performance.
- Motor is suitable for home use
- Solid construction
- Inconvenient positioning of the grinding wheel
- Substandard tool rests
- Wobbly wheels
4. WEN 4286 – Bench Grinder
The WEN 4286 is another slow-speed 8-inch bench grinder. Its powerful 3 HP motor spins its wheel at 1750 RPM speed.
This makes it a reliable choice when it comes to general sharpening, cleaning, deburring, and trimming.
You can switch between the two included wheels to extend their lifespan.
As for the safety features, the WEN 4286 comes with a robust base that eliminates any vibrations and wobbling. The protective glass is also sturdy and works well at keeping dust and debris away from your working area.
The combination of a slow-spinning speed and powerful motor enable you to grind and cut through hardened steel and sturdy materials.
- Powerful motor
- Comes with two wheels
- Easy to set up
- Great safety precautions
- Not suitable for heavy-duty tasks
5. DeWalt DW756 6 inches – Bench Grinder
Shaping metals is a breeze when you use the DeWalt DW756. Its 5/8 HP motor enables the wheels to spin at 3450 RPM, which is suitable for taking on many improvement projects.
The grinder is designed to let you position your workpiece in a way that maximizes the efficiency of the cuts. Moreover, the generous distance between the wheels allows you to do advanced projects.
It comes at a pretty affordable price as it’s made in China. That doesn’t compromise the quality of its construction, however, as it’s a robust machine.
The DW756 has an industrial cast iron base with a durable motor housing to extend its lifespan. With this long life cycle, you get a high return on your investment.
Moreover, it has rear exhaust ports to provide a better and smoother operation.
The spark deflectors and eye shields further extend the safety. However, I think the time it takes to stop is a little too long.
- Intuitive design
- Potent motor
- Premium-quality construction
- Effective exhaust ports
- Suitable for heavy-duty grinding
- Not the best design
- Can use some stability
6. Jet 577102 JBG-8A 8-Inch Bench Grinder JET
This bench grinder isn’t made for your simple DIY jobs around the house but rather for heavy-duty, professional-grade work.
And that explains why it’s so heavy at 58 pounds. It doesn’t occupy that much space though as it measures 19 x 10 x 12.5 inches.
With a powerful 1 HP (8 AMP) motor and 8-inch wheels that can spin at 3450 RPM, the Jet 577102 can effortlessly cut through the toughest materials.
Moreover, the 8-inch wheels come in two variations: a 36-grit option and a 60-grit one to enable you to grind rough edges as well as finish more delicate tasks.
The enclosed, pre-lubricated ball bearings make its operation very smooth and keep its rotation consistent.
Furthermore, its massive base makes it sit sturdily on the ground to provide some stability.
And to provide you with safety, the Jet 577102 comes with big spark guards and eye shields that are simple to adjust. However, the addition of work lights would have gone a long way in terms of convenience.
- Durable with a 2-year warranty
- Stable performance
- Powerful motor
- Easily adjustable
- Doesn’t come with work lights
- Not portable
7. Metabo DS 200 – Bench Grinder
Although the Metabo DS 200 is a little more expensive than most options on the list, I think that it’s an excellent investment in the long run and that its performance is worth the money.
It has a powerful 1 HP motor that’s easy to maintain and that can spin the wheel at variable speeds according to your needs with a 3570 RPM no-load speed.
You can use it to sharpen or smoothen whatever metal you need, including even axes and chisels.
Moreover, the Metabo DS 200 is quite durable with a sturdy die-cast aluminum cover as well as a fast-locking bayonet for protective cover.
And although it’s an industrial-grade bench grinder, it’s quite portable at 35.9 pounds. And at 13.1 x 12.9 x 18.3 inches, it’s not the most compact, but it still doesn’t require that much space.
On top of that, it doesn’t produce much noise or vibration as it operates.
Initially, the Metabo DS 200 is a little hard to set up. But once you get it done, you’ll get a fantastic level of performance.
- Variable speeds for versatility
- No vibration
- Powerful motor
- Accessible off button and auto shutdown feature
- Set up is a little tough
- A little pricey
8. Craftsman 921154 Bench Grinder
The 1/5 HP motor may not be the most impressive on the market, but it still spins the wheel of the Craftsman 921154 at variable speeds between 2000 RPM and 3400 RPM.
And although the speed is relatively higher than most options on the market, I’d say this unit is the best bench grinder for woodworking and not metal as its horsepower is not strong enough.
At this speed, the 6-inch wheel can swiftly sharpen tool blades and chisels.
And to provide you with stability as you operate it, the Craftsman 921154 comes with an oversized cast-iron base that reduces vibrations.
Moreover, the Craftsman 921154 is a wet grinding machine. This means that it has a built-in cooling system that protects its motor from overheating.
Combining the spark guards, clear eye shields, and a built-in light gives you maximum visibility and safety.
- Reasonable price for the features
- Versatile functions thanks to the variable speeds
- Equipped with a wire wheel
- Built-in light for more visibility
- Tool rest is a little too small
- Produces some hum while running on lower speeds
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. It can be used with wood or metal depending on the strength of the wheel and how fast it spins.
You can use your bench grinder to shape or buff wood if it’s a slow speed bench grinder.
If it’s a fast speed one, 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.
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 fit more delicate grinding operations such as shaping metal.
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.
The speed of a bench grinder is measured in RPM (Revolutions per Minute), and it depends on the horsepower of the motor.
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 grinder if you’re going to be working with wood or softer woods.
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.
There are three major grit 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.
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 drill bits as well as anything made from silicon carbide such as carbide tools.
You should make sure that the bench grinder that you get complies to the safety standards of the industry with enough safety precautions.
Wheel guards should cover 75% of the 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 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 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.
If your grinder isn’t a “wet grinding machine,” you’ll need a bucket or a pot with water to dip your workpieces in to keep them cool.
Wet grinding machines are grinders that have built-in cooling systems to prevent them from overheating.
While all the grinders I’ve mentioned are great, I’d say the DeWalt DW758 is the best bench grinder 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 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.
