Uses of Angle Grinder Using an abrasive or diamond wheel, cutting metal is one of the common uses for an angle grinder. It can be a less expensive alternative to a plasma cutter for fabricators. Masons can use them to cut off rebar. Commercial contractors might use a grinder to cut metal studs. Pros in the oil/gas and plumbing industries use them to cut metal pipes. Around the house and garage, it’s great for cutting off frozen bolts, trimming down threaded rods, and cutting metal to shape for a variety of weekend projects. Because of their thinner nature, abrasive cut-off wheels have a higher risk of coming apart, so be sure you’re always using the guard and safety glasses. You might want a thick apron as another layer of protection for your chest. Polishing Metal When you use an angle grinder for grinding and polishing metal, there are several wheels you might use. Some remove material aggressively and help you remove bumps or grind down welds so they’re flush with the connection. Other wheels remove material less aggressively and can even out the look or bring the metal back to a beautiful smooth shine. Then there are polishing wheels you can use to add a polishing compound to give the metal its best finish. If you want to spend more time smoothing and polishing, look for an angle grinder with adjustable speeds. You’re less likely to damage your workpiece at slower RPMs, and grinders don’t have variable speed triggers. One of the most common ways to use an angle grinder around the house is to sharpen your lawn mower blades, axes, and hatchets. It’s arguably easier with a bench grinder, but plenty of people use angle grinders effectively. It’s a rough process and you’ll want to follow up with a sharpening stone to get the best edge.
