Cobalt 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

Longer overall length but shorter flute length for maximum rigidity

Used where extra reach is required or for drilling holes in hard-to-reach places

Ideal for low carbon, stainless steel and other ferrous metals.
