Factors to Consider Before Buying an Electric Die Grinder

  • Collet Size. The collet size gives you information about the size of bits that you can connect to the holder of your tool. Manufacturers usually mark this detail on the machine itself, but you should check this before buying it.

    Usually, die grinders have a collet size of ¼ inch that is quite common, and you can find a wide range of bits for this size.
  • Power Rating. Power rating is essential to have a clear idea about the power of an electric die grinder. The most commonly used voltages for an electric die grinder are 18 and 20 volts, which means that the maximum power input to the motor should be 360 watts.

    These motors tend to produce RPM 1,000 or more, which is required for grinding metal. If you see a motor with any other voltage than these mentioned then you should avoid buying it as it uses more electricity but at less power.
  • Size and Form Factor. Size and weight are some of the primary things you should be looking at. With size, you should be looking for a tool that is small and compact due to its form factor.

    If it’s small and compact, chances are you can get to work with it using a single hand and will have a good amount of control over it while in use.

Frequently Asked Questions

What is a Die Grinder Good For?

Die grinders and their larger cousins, rotary tools, are two of the most versatile handheld power tools in a DIYer’s garage.

Die grinders exist for the purpose of removing sharp edges after metal parts have been formed or machined. Die grinders can also be used to remove metal burrs from surfaces you may have forgotten to deburr.

Can You Use a Die Grinder to Cut Metal?

Die grinders are a wonderful addition to your garage or workshop. The powerful motors on grinders offer great maneuverability and they make effortless work of cutting through all sorts of materials depending on the attachment you choose.
