Buyer’s Guide

How do Angle Grinders Work?

Angle grinders are small tools used for doing just what they’re named after, which is grinding. They’re handheld but very powerful, spinning at a rapid rate that averages about 7000 RPM at its lowest. Some angle grinders have a much higher RPM, particularly those that are plugged.

Wheels are attached to the grinder, sometimes called blades. The standard wheel for most Dewalt grinders is 4-1/2 inches. Some are also five and seven inches.

Why Angle Grinders are Needed

Angle Grinders are used for grinding down cinder blocks, cutting masonry, tiles, and even sharpening tools. Many purchase the grinders with a low RPM specifically for sharpening lawn blades. Looking online, you’ll see people using them for lots of things, though what you try it on should be carefully considered and researched if you’re not sure.

Why You Should Use an Angle Grinder

Angle grinders can take the place of hands when sanding, cutting welded metal, and slicing through bathroom and kitchen tiles. People doing interior decoration in such places would definitely need an angle grinder at some point.

They’re useful for making pinpoint cuts and preparing tiles before their installation on the floor and countertops. Keep one in your tool shed or garage and you’re bound to need it at some time in the future.

Finding the Right Brand for You

Although Dewalt makes outstanding anglers, they’re not the only products that are suggested. But what makes the brand stand out is their quantity and durability of angle grinders. Dewalt manufactures a large amount, each one of them having unique features that are useful for either beginner, intermediate, or professional users of these tools.

Another is compatibility with the environment. Dewalt’s angle grinders are AC/DC powered, battery-operated, and built to safely fit the most common grinder types.

Understanding the Functions of Angle Grinders

To use a grinder, you’ll first need to find out the wheel size that you need. The average grinder is 4-1/2 inches, meaning that wheels measuring 4-1/2 inches will fit on the grinding wheel. To attach, either a hex key or another wrench is used to tighten. In those with brushless motors, fewer obstacles are required to change out the wheels.

Frequently Asked Questions (FAQ)

Will Kickback be a Problem?

Kickback can occur with spinning power tools, due to their fast-moving parts. Kickback is a recoil, either from the wheel or the object being manipulated with the machine. Although kickback can be avoided, safety measures put in place by the product itself and accessories worn by the user make using grinders a safe thing to do. Always use gloves and eye protection when handling a grinder.

Are Angle Grinders easy to Handle?

Most angle grinders have two handles, in the rear and another on the left side of the wheel. Since both hands are used, steadying the grinder while cutting is relatively easy.

What Wheels are Compatible with an Angle Grinder?

For this, you’ll have to do your homework. Most grinders will obviously take a grinding wheel, though some type number may not fit well with the product. Check with the manufacturer and ask about wheel compatibility before purchasing.


Of the 15 angle grinders shown in the list, each one can work great for the people and jobs they’re recommended for. If you read through the reviews, you know that experience isn’t important, since there’s a grinder for every person’s level of expertise. There’s no right or wrong product to pick, so get the one that has the features that you need!
