Round- and Hex-Shank Masonry Drill Bit Sets for Hammer Drills
Drill holes using simultaneous rotary and hammering action to break masonry material into tiny granules. These bits drill faster and penetrate material with less pressure than rotary-only bits. Also known as percussion or impact bits.
Serrated-point drill bits deliver faster, cooler cutting as well as longer life than standard-point masonry drill bits.

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.

High-Speed Steel Drill-Point Countersink Sets
with Two Countersinking Ends for Screws
Turn the countersink around when one end dulls for a sharp cutting edge. The countersinks in these sets have a small drill point on the tip for drilling and countersinking holes with the same tool. The drill point creates a small pilot hole at the bottom of the countersunk hole to facilitate drilling. An 82° countersink angle is compatible with the profile of flat- and oval-head inch screws; a 90° countersink angle is compatible with the profile of flat- and oval-head metric screws and is also good for deburring.
