STEP DRILL BITS An excellent tool for electrical contractors, sheetmetal workers and auto mechanics. Step drills are ideal for drilling repetitive holes in steel, copper, brass, plastic, plexiglas and other thin materials. Made of high speed steel with double fluted ground cutting edge for long life. TiN (Titanium Nitride) coated step drills are offered in our most popular sizes. The coating on these step drills allows them to last up to six times longer than those made without TiN coating.
