Angle grinders are a handheld tool that use a rotating disc for cutting, grinding and polishing. Cordless angle grinders can be either petrol or battery powered operated, and have the advantage of full portability and mobility unrestricted by the need for a power point or generator.

Please see our angle grinder guide for help choosing the right model to suit your requirements.Which Cordless Angle Grinder?When considering which cordless angle grinder to buy, it is important to consider your intended applications and the capabilities of the tool.The first consideration is which disc size the angle grinder is capable of carrying. Larger discs are typically used for heavy duty applications, with smaller discs used for finer work. Usually, there are discs specifically suited to cutting applications, and discs suited to abrasive applications.Another consideration is the maximum no load speed of the grinder. This is important, as it must match the capabilities of your disc. Using the wrong disc at the wrong speed can not only put undue stress on your angle grinder, but may result in personal injury.Why Go Cordless?The principal advantage of a cordless grinder is its mobility.
