    Product Description

  • 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
