The 3 in 1 multi disc can be used for cutting, grinding and finishing applications simply by altering the angle at which the disc is used. 90 degrees for cutting, 30 degrees for grinding and 15 degrees for finishing. An extra layer of reinforcing has been added to the disc to ensure that it can cope with additional side pressure from grinding despite the 2.5mm thickness (thinner than a standard cutting disc), guaranteeing a fast, straight cut. The disc is also INOX meaning it can be used on stainless steel with any risk of material contamination or rust formation. For use on Stainless Steel, sheet metal, mild steel and high grade steel.
