A large number of new abrasives - and more powerful right angle grinders - have been introduced in the last several years that al-low improved cutting, grinding and finishing, and anyone involved in the metalworking industries should know that choosing the correct tool and abrasive can reduce finishing time and costs. The right angle grinder is the most widely used tool in any metalworking shop. New developments in the grinder itself include more powerful variable-speed motors, improved ergonomics, and designs that dampen vibration. When using the right angle grinder to perform different tasks, newer grinders allow the user to adjust the speed of the grinder. This becomes critical when the operator changes from grinding to polishing. Polishing requires slowing the speed for finer finishing, and that becomes critical to the aesthetics of the final finish of the surface.
