M42 (8% Cobalt) - cobalt drills offer increased hardness,

1/4"-28 threaded shank provides a secure fit in the tool holder

Toughness and better wear resistance compared to regular HSS

Black oxide finish for increased wear resistance and added lubricity

135° Degree split point for fast penetration and accurate starting (self-centering) which eliminates "walking" and reduces the thrust force needed

Used in portable angle drilling tools for drilling harder, tough high tensile materials in confined areas

When drilling low tensile strength materials, these drills will have significantly greater tool life vs. standard HSS
