Cobalt Steel Drill-Point Countersink Sets for Lathe Centers
With more heat and abrasion resistance than high-speed steel, cobalt steel is often used on hard-to-machine materials. The countersinks in this set have a 60° countersink angles that’s compatible with the profile of centers on a lathe. They have a small drill point on the tip for drilling and countersinking holes with the same tool. The drill point creates a small gap that prevents damage to the points of live or dead centers. Turn the countersink around for a sharp cutting edge when one end dulls.
