UPDATED: August 18, 2020.

If you are looking for the best overall, I recommend the DEWALT DCG413B 20-Volt MAX because it features a portable cordless design, variable speed up to 9,000 RPM, and a kickback brake.

Angle grinders are a versatile power tool, essentially a hand-held bench grinder, used for polishing and cutting with an abrasive disc (also called a cutting wheel). The discs are interchangeable with either a wrench or a “quick change” setup, depending on the particular tool.

The type of disc determines the kind of work that can be done. For example, grinding discs can be used for removing excess metal from a welding and wire brush wheels can be used for polishing. Disc sizes can vary but the common dimension is 4-1/2″.

Standard methods of powering an angle grinder are corded and cordless. Air-powered grinders are also common.

Grinders are loud, produce sparks, and the discs can shatter. For these reasons, you should always wear appropriate safety projection including ear plugs, gloves, eye protection (safety goggles and/or face shield) and protective clothing. The project being worked on should also be held securely in place with either clamps or in a vise.

The following angle grinders use the latest innovative components to meet your needs and help to ensure you do your best work.

Find the best angle grinder for your needs.
