Features
Designed for hard metals (stainless steel, alloy steels, cast iron) where standard HSS bits wear quickly
1/2″ reduced shank design with cobalt alloy construction provides higher heat tolerance during high-speed or deep-hole drilling
Precision-ground cutting edges promote consistent hole size and smoother entry in tough materials
One-piece configuration reduces wobble and improves alignment in high-load applications
Ideal for fabricators, automotive work, and maintenance tasks requiring large-diameter holes
Recommended practice: use cutting fluid or coolant and steady feed to maximize bit life
