An angle grinder, also known as a side grinder or disc grinder, is a handheld power tool used to grind, polish, and cut, especially in metalwork and construction. Angle grinders often have replaceable blades for different purposes.
You can find angle grinders powered by electric motors, petrol engines, or compressed air drives. Smaller angle grinders also generally have smaller discs and are useful for more delicate work. Cut to the chase with your own angle grinder.
