About This Project

I used to think an angle grinder was only good for grinding metal. Then I saw a tile setter using an angle grinder with a diamond wheel to make intricate cuts for a tile backsplash and realized the tool’s potential. Now that I own an angle grinder, I’ve found all kinds of uses for it. Cutting tile, mortar, stucco and pavers is easy with a diamond wheel. Wire brush attachments make quick work of rust and loose paint removal. Special abrasive wheels can cut or grind steel. We’ll show you how to use your angle grinder with special wheels to accomplish a number of common but difficult cutting, grinding and polishing tasks.

You’ll find angle grinders anywhere power tools are sold. Larger grinders are available, but the popular 4-in. and 4-1/2 in. grinders are the right size for most tasks. You can buy an angle grinder for as little as $40, but for frequent use or for demanding jobs like cutting stucco or cement, I’d recommend spending $70 to $110 for a grinder with a more powerful motor (look for a motor that draws 5 to 9 amps).

The ability to handle different wheels and accessories is what makes angle grinders so versatile. Your angle grinder includes a spindle washer and spindle nut that you’ll install.
