Greenlee Textron’s 628 and 648 Carbide Cutter sets feature six cutter sizes ranging from 7/8” to 2 1/2”. They cut holes in stainless-steel, mild-steel, iron, copper, brass, aluminum, fiberglass and plastic sheets up to 3/16” (4.8mm) thick. Tungsten-carbide teeth allow for fast cutting of round, burr-free holes. There is a flange stop for added safety and an ejector spring that automatically removes the slug with every cut.
