The 5 Best Bench Grinder for 2020

1. DeWalt DW758 - Best Bench Grinders


Running on a Âľ HP induction motor, the DeWalt DW758 bench grinder provides you with enough torque to turn its 8-inch grinding wheels.

And despite its power, it’s still quite compact and doesn’t occupy that much space.
So whether you’re going to do resurfacing or polishing, your work will be done effortlessly.Furthermore, the DeWalt DW758’s bench grinder motor is capable of spinning its wheel at 3,600 RPM speed –a number that’s superior to most bench grinders of its price level.

This means that its action is much quicker and seamless no matter the workload.


Grinding Wheel

The DeWalt DW758 bench grinder comes with two 8-inch grinding wheels that are ready to take on heavy-duty work.

Combine that with the big arbor width that gives you the ability to work with larger stock and tools and you get all the versatility you need.

Moreover, they’re quite solid and firm, so you won’t experience any vibrations or instability.

The machined-aluminum tool rests are made from solid blocks and therefore provide the best stability for the most accurate results.

Also, there's a big gap between both grinding wheels that measures 12.5 inches and allows you to work with larger projects without facing any issues.

Debris Exhaustion and Noise

To get rid of any dust and debris and to keep your work area clean, there’s a rear exhaust pipe that evacuates all the resultant debris.

However, the DeWalt DW758’s noise-control isn’t as good as its dust collection.

This is especially true if you're grinding metal or working it at full load. Nothing that a pair of earplugs wouldn't fix, however.


The DeWalt DW758 bench grinder comes with a pretty sturdy base that’s made from solid cast-iron and provides you with sufficient surface area for rigidity and stability.

With the inserts, you can even bolt it to your workbench or your floor for maximum stability even with large workloads.


As for the safety precautions, the DeWalt DW758 bench grinder comes with a clear view spark protector which you can adjust to get the optimal visibility and protection.

However, there's no working light provided with this model.

2. WEN 4286 - Best Bench Grinders


The WEN 4286 bench grinder runs on an impressive 3 HP motor, however, its grinding speed is lower than average at only 1,750 RPM.

That doesn’t mean that it underperforms as it’s the best slow speed bench grinder that allows you to work with tougher materials with the smoothest performance.

It does a great job at deburring ragged edges, sharpening, and cleaning objects.


Grinding Wheel

With the WEN 4286 bench grinder, you’ll get two 8-inch diameter wheels so that when one starts getting worn out, you can replace it with the sharper extra.


Maintaining solid performance without any movement on any surface is made possible thanks to the sturdy base.


The protective glass of this grinder safeguards you from any debris or dust that may come flying off.


  • Powerful motor

  • Comes with a spare wheel

  • Easy assembly and set up

  • Able to handle very tough materials

3. Jet 577102 - Best Bench Grinders


Rated for heavy-duty operations, the Jet 577102 bench grinder comes with a 1-HP (8 AMP) motor that can spin its wheels at a speed of 3,450 RPM –which is more than sufficient for most DIY jobs and light to medium-duty tasks.

Moreover, its operation is very smooth as it comes with pre-lubricated ball bearings that are completely enclosed and keep the spindle rotating.


Grinding Wheel

You get two 8-inch wheels: a 36-grit one and a 60-grit one. The former helps you work your way around rougher edges while the latter suits more delicate tasks.

Debris Exhaustion

The dust collection ports do an effective job of keeping all the debris away from your working area.


The Jet 577102 isn’t the most compact or lightweight grinder around, so while it’s not very portable, it sits sturdily on whatever surface.

Additionally, its heaviness reduces the vibrations during operation.


Moreover, the spark guards and eye shields are quite large and easy to adjust, so they provide you with the safety needed to work seamlessly.


  • Sturdy performance with a 1 HP reliable motor
  • Adjustable eye shields
  • Effective dust exhaustion
  • Guarded heavy-duty toggle switches
  • Fully enclosed unit


  • Wobbly wheels

  • Quite pricey

Bottom Line:

Although a little high in price, the Jet 577102 gives you amazing value in return. With its premium-build quality, reliable motor and operating speed, it’s a top-notch long-term choice.

The 5/8 HP of DeWalt DW756 bench grinder gives you ample power to turn the wheels at a speed of 3,450 RPM to get even and fast material removal.

No matter how hard you press on them, the grinding wheels wouldn’t stall.

And while the motor may not be the most powerful, it employs a great technology that delivers the maximum efficiency while consuming the least power consumption.

In addition, the cast-iron housing works on dissipating heat and extending the motor’s longevity.


Grinding Wheel

The DeWalt DW756 comes with two 6-inch diameter wheels and a ½-inch arbor size –the standard dimension on most grinders.

One of the wheels is 36-grit for surface removal and the other 60-grit one is for polishing and sharpening.

The heavy-duty stone mineral construction is quite impressive and can handle heavy-duty tasks on a daily basis.

Finally, the 12.5-inch gap between the two wheels gives you ample space to work with larger tools.

Debris Exhaustion and Noise

The 5/8 HP motor isn't that big and consequently, it doesn't produce that much noise. You'd still need ear protection while you operate the unit –especially if you do it in a confined space such as a workshop.


You can rely on the DeWalt DW756’s stability as its cast-iron base is large enough to keep it standing sturdily.

And the best part is that there are insert holes on the base that allow you to fix it to a workbench.

    How to Choose a Best Bench Grinders?

    Grinding Wheel

    Grinding wheels can come in a variety of sizes to fit different purposes. And that’s why you should identify your purpose –especially if you buy a grinder with a single-sized wheel.

    Bigger diameters are used for bigger tools and vice versa. Moreover, you should pick larger grit sizes if you’re going to work with tougher materials or if you want the smoothest results.


    There’s no denying that more expensive units would be more durable and last longer, but that doesn’t mean you have to break the bank when it’s time to buy a grinder.

    Just make sure that the construction doesn’t include many plastic parts and that you provide your unit with regular maintenance.


    How powerful your bench grinder motor is will affect the tasks and materials you can take on.

    A more powerful motor allows you to do heavy-duty jobs and process larger, harder metals.

    If you’re going to be working on lighter tasks, however, there’s no need to spend extra money on large motor power as ½ or 1 HP would be good enough.

    Although the WEN 4286’s speed is on the low side, its powerful motor allows you to take on very tough materials without the unit heating up.
