Step drills are ideal for drilling repetitive holes by electrical contractors, sheet metal workers, and auto mechanics. HSS drills are made of high speed steel with double fluted ground cutting edge for long life. Morse also carries TiN coated drills to reduce friction, allowing the bits to last up to six times longer than HSS drills.

Increase accuracy when drilling with 3 flats on shank for secure fastening in drill
Faster penetration than standard points with split point tip for self starting drills
Re-sharpenable cutting edges allows for longer tool life
