An angle grinder is a handheld power tool that can be used for a variety of metal fabrication jobs that include cutting, grinding, deburring, finishing, and polishing. It is a versatile tool that can be used for many things, depending on what disc, cutter, or other attachment youre using. Here are some of the primary uses of an angle grinder:
-
Cutting metal: 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 an angle grinder to cut metal studs. Pros in the oil/gas and plumbing industries use them to cut metal pipes.
-
Grinding/polishing metal: Angle grinders can be used to restore scratched metal and polish it. 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.
-
Cutting masonry, stone, and tile: An angle grinder can be used to replace a larger tile saw to cut ceramic tiles, concrete paving stones, and many other types of stone. For this type of work, you would need either a cutting disc that specifies use with masonry or (more commonly) a diamond blade. Diamond blades often cost a bit more but will last significantly longer and cut faster.
-
Cleaning metal: Angle grinders can be used to clear rust and clean metals. Using a wire brush, you can easily clean metals such as shovels and tools.
-
Clearing grout: An angle grinder can be used to clear grout from between tiles.
-
Sharpening blades: Angle grinders can be used to sharpen blades such as lawnmower blades, axes, and hatchets.
-
Sanding wood: With the right attachment, an angle grinder can be used to sand wood.
It is important to note that an angle grinder is a powerful power tool and should be used with care. Whether used to grind, cut, or sand and whatever material, you should be using appropriate personal protection equipment (PPE) to protect your hands, ears, and eyes, while covering your mouth and nose.
