What to check before you order

  • Wheel size and arbor. The grinder determines the wheel diameter and arbor thread. Buy grinding and cut-off wheels and flap and fiber discs that fit.
  • Speed rating. The wheel or disc's maximum RPM must meet or exceed the grinder's rated speed.
  • Guards and handles. Keep the guard installed and positioned as the manufacturer directs, and use the side handle.
  • Switch type. Paddle switches with a no-lock or lock-on option and electronic brakes are common features. Your site may specify which are required.
  • Sander pad size and hook pattern. Match discs and sheets to the pad, and choose the grit for the finish you need.

Shop all power tools, sanding belts, sheets and pads, and eye and face protection for grinding work.

Common questions

What is the difference between an angle grinder and a die grinder?

An angle grinder drives a wheel or disc at a right angle to the motor and is used for cutting, heavy grinding and surface prep. A die grinder holds small mounted points, carbide burs and sanding rolls in a collet and runs at higher speeds for detail work, deburring and porting.

What does random orbit mean on a sander?

A random orbit sander spins the pad while also moving it in a small offset orbit, so the abrasive grains do not follow the same path twice. That leaves fewer swirl marks than a sheet sander that vibrates in a fixed pattern.
