    Product Description

  • Cobalt stub drills offer increased hardness, toughness and better wear resistance compared to regular HSS
  • Gold oxide surface finish provides a polished finish and prevents chip building, galling and welding on a workpiece
  • 135° Degree split point for fast penetration and accurate starting (self-centering) which eliminates "walking" and reduces the thrust force needed
  • The short flute and overall length provide maximum rigidity, hole accuracy, and tool life
  • Cobalt drills are suitable for harder material including alloy steels, stainless steel and other difficult to drill materials
