DEWALT DW758 8-Inch Bench Grinder
It should come as no surprise to anyone that DEWALT’s DW758 is one of the best bench grinders around.
This 8-inch grinder was designed to be as user-friendly as possible, but that doesn’t mean DEWALT’s engineers have skimped on power.
The DW758 will handle almost any material or tool that you throw at it and it should last for decades as long as it remains well-maintained.
DEWALT’s DW758 has a 3/4 horsepower motor that produces 1400 inch-pounds of torque, and that is one of the reasons why it is often compared to industrial bench grinders instead of entry-level grinders.
It is a solid choice for heavy-duty applications as well as smaller projects around the home. With high-quality wheels and grinding stones, the DW758 has a maximum rating of 3,600 RPM.
The first thing that you are going to notice when you use this bench grinder is its sturdy construction. All of the parts have been designed to produce minimal vibrations.
Even after extended use, you won’t have to worry about the tool ‘wandering’ away from the workpiece as long as it is on a sturdy bench or stand.
While this tool doesn’t come with a work light, it does include two adjustable tool rests as well as impact-resistant guards.
There are two key design features that set the DW758 from dozens of other bench grinders. DEWALT’s design team has included two rear exhaust ports in order to make the user as comfortable as possible, and you have the option of attaching hoses if your workshop has an exhaust system.
The DW758 also has an elongated driveshaft that gives you a much larger area to work in, and the total distance between the two wheels is just over 12-inches.

Buyer’s Guide – Main Features to Consider
A bench grinder’s maximum speed is measured in revolutions per minute. A machine that is rated for high RPM will remove an incredible amount of material in a short period of time, but you can accidentally damage the piece if you aren’t careful.
Slower grinders are usually designed for general projects around the home because they are easier to use and slightly safer.
Have you outgrown your slow bench grinder?
If your old bench grinder seems to be underpowered, then you might want to upgrade to a faster model. You also need to make sure that you only use high-quality grinding wheels with industrial bench grinders.
The price of a bench grinder is almost always determined by two distinct factors. The first factor is the overall power that the bench grinder can produce. An industrial bench grinder will have a powerful motor that can quickly get up to speed. It is going to strip away denser materials without overheating the motor.
You are also going to pay for the brand when purchasing one of these tools. World-class tool manufacturers usually back their tools with unparalleled warranties and other guarantees.
When purchasing a bench grinder, the most important safety feature to consider is the guard. A sturdy guard will protect you from any sparks or shards that fly off the material.
As a general rule, you want to stick to bench grinders that have adjustable guards made from durable materials such as impact-resistant plastic.
You should also take a closer look at the tool rests near the grinding stones. Flimsy tool rests can sometimes move around when you are aggressively grinding, and that could result in a serious accident.

Bench Grinder vs. Angle Grinder
While these two tools are similar, there are a few differences that you should be aware of before you make a decision on which is the best angle grinder for your needs.
The biggest difference between an angle grinder and a bench grinder is the portability. An angle grinder is a handheld tool that is powered with a battery or power cord. The vast majority of angle grinders only weigh a few pounds, and you will be able to take that tool with you to any job site.
Even though some bench grinders come with portable stands, that are generally installed in a single location. While using a bench grinder, you will hold the piece that you are working on instead of the tool itself. With an angle grinder, you must work on a stable piece of material or clamp the piece to a stable surface.
Are you in need of a precise grinder for your home or commercial shop? If that sounds like your own situation, then you should probably invest in a bench grinder. While a bench grinder is heavier an angle grinder, it will also be easier to use and much more precise.
Many people are surprised to hear that a grinding wheel can sometimes be as expensive as a bench grinder. That being said, a high-end diamond grinding wheel could easily last a lifetime as long as you don’t abuse it.
Like sandpaper, grinding wheels are typically classified by their overall grit. Grinding wheels that have low grits are designed to remove more material, but they won’t give you a polished or clean look. Buffing pads and wire wheels can be attached to bench grinders as well.
Those accessories are used for very specific jobs such as polishing soft metals or removing layers of rust.
How To Use
Is your new bench grinder set up and ready to go?
After you have set up your bench grinder and read the owner’s manual from front to back, you can start your first project. Unless you have quite a bit of experience using one of these tools, you should practice on a few spare pieces of metal.
Once the tool is on and the grinding wheel is up to speed, you can place the item on the tool rest and slowly push it toward the grinding wheel. While you are removing material, your primary goal is to make short and consistent passes.
Being too aggressive with a bench grinder is a bad idea, and it can lead to damaged tools or serious injuries. You want to apply just enough pressure to remove a thin layer of material.
You also need to stop whenever the workpiece is getting too hot. Softer metals and plastics could begin to melt after one or two passes, and you might need to douse them in water or oil every few seconds.
Many professionals also wear heavy-duty boots and leather aprons to prevent cuts and burns. As for gloves, that depends on what piece you are working on. Gloves should only be worn if the workpiece is long enough to keep your hands at least a few inches from the grinding stone.
Some of the materials that you grind and hone might be toxic as well, and that means you need a respirator and proper ventilation.
At the very least, you need to invest in a half-mask respirator with a HEPA filter. Those respirators filter out most toxins and are relatively inexpensive.
Some bench grinders come with exhaust ports that can be attached to exhaust systems, but those are usually only needed in industrial settings.
Do grinding wheels need to be dressed regularly?
Dressing a grinding wheel squares the face and exposes new grit. Most wheels need to be dressed after a few minutes of vigorous grinding.
How do I sharpen and hone at an angle?
Many companies sell honing guides and jigs that allow you to hold the workpiece at a very specific angle, but an adjustable tool rest should work as well. If the angle is extremely important, then you need to invest in a digital angle finder.
DEWALT’s DW758 is a general-purpose grinder that is perfect for home and commercial use. Its 3/4 hp induction motor gives this grinder plenty of power for a wide variety of projects.
This tool can be set up and attached to a stand or workbench in two or three minutes, and you won’t have to worry about excessive vibrations or wobbling grinding wheels as long as you follow all of the instructions.
Are you tired of outgrowing your tools?
A bench grinder can be a major investment, but you won’t ever have to worry about outgrowing the DW758. Its oversized tool rests and wide body will let you tackle larger workpieces as you get more used to grinding, honing, and sharpening.
The DW758 is also backed by DEWALT’s 3-year warranty and one-year service contract. DEWALT covers all faulty parts and will replace worn components at no charge to you.
