Grinders and disc grinders are types of heavy-duty handheld power tools. Grinders are used to cut, polish and grind a variety of materials such as concrete, metal and stone via various spinning discs that can be securely attached. Like other power tools, they are available with motors that are brushless to prolong life and deliver more power. Brushless motors also include safety features such as dust ejection systems, no-volt releases switches, anti-restart and anti-vibration handles.

Grinders are available in a range of sizes from slimline designs for working in confined spaces with precision to larger heavy-duty builds for professional regular use. They are commonly used by DIY enthusiasts and professionals such as builders, plumbers, electricians, carpenters, mechanics.

At RS Components, we offer a wide range of reliable and durable grinding tools from major brands such as DeWalt, Bosch, Makita. Find out more in our complete guide to angle grinders.

Types of Grinders

  • Corded Angle Grinders: Powered by electric, these are widely used in metalwork fabrication and construction. This type is ideal for professional use when constant power is required. Corded grinders tend to be heavier but are ideal for heavy-duty applications.

  • Cordless Angle Grinders: Battery-powered offering the same operating properties as a corded angle grinder. These grinders are portable and offer greater safety as there are no cables to manoeuvre around objects or personnel. Ideal for DIY, workshops and fabrication applications.

  • Compressed Air Angle Grinders: Air-powered, thumb trigger controlled and generally used for light duties where more precision is required. These grinders can be small and light but remain powerful, as they do not contain heavy motor windings.

  • Die grinders are a type of hand-held power grinder used for grinding, sanding, honing or polishing material (typically metal, but also plastic or wood) that use the capability of a battery pack for great portability.
