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
