11-Piece Left-Hand Cobalt Screw Machine Drill Bit Set
Description
Description
The Drillco 300LH11 Left-Hand Cobalt Drill Bit Set is designed for removing broken bolts, screws and other damaged fasteners. Featuring premium M-42 cobalt high-speed steel construction, these drill bits provide excellent heat resistance, wear resistance and cutting performance when working with hardened metals.
Designed with left-hand cutting flutes, the bits rotate counterclockwise to help loosen and extract broken right-hand threaded fasteners during drilling. The 135° self-centering split-point reduces walking and improves starting accuracy, while the bronze surface treatment provides added lubricity.
The shorter screw machine length offers increased rigidity and reduced breakage, making this set an excellent choice for mechanics, machinists and maintenance professionals.
