The H-11-001B-S03 is a Spiral Flute HSS – Cobalt Step Drill Set of 3 in HSS Cobalt 5% (M35).
Hole making starts with a twist drill and rarely finishes there. Step drills open and enlarge holes in sheet without a pilot change, countersinks cut the recess a flush screw head needs, and reamers bring a drilled hole to a precise finished size and surface.
Spiral flutes reduce vibration and improves surface finish, while allowing higer penertration rates
HSS Cobalt step drills provide increased tool life in difficult to machine materials
TiN coating improves heat and wear resistance
3 Flats on shank to increase drill chuck clamping power
