Insert these bits directly into power screwdrivers, impact drivers, and other tools that accept 1/4" hex shanks. They are titanium nitride (TiN) coated for wear and temperature resistance.

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.

Drill holes using simultaneous rotary and hammering action to break masonry material into tiny granules. These bits cannot be used with SDS-Max-drive rotary hammers. Drill holes using simultaneous rotary and hammering action. This type of bit drills faster and penetrates material with less pressure than rotary-only bits. Also called percussion or impact bits.

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.
