Cobalt jobber 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 (self-centering) which eliminates "walking" and reduces the thrust force

Cobalt drills are suitable for harder material including alloy steels, stainless steel and other difficult to drill materials
