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

Steam oxide surface treatment increases lubricant retention and wear resistance and reduces chip welding

The short flute and overall length provide maximum rigidity, hole accuracy, and tool life

Suitable for various steels, stainless steel and sheet metal
