Cobalt Steel Morse Taper-Shank Drill Bits
With better heat and wear resistance than high-speed steel, these cobalt steel bits can run up to 25% faster and have a longer tool life. Install the Morse taper shank directly into the tapered spindle on machines such as drill presses and lathes. A split point keeps the bit centered without a pilot hole.
Titanium-nitride (TiN) coated drill bits last longer and can drill at higher speeds than uncoated drill bits.

Tapered-Round-Shank Masonry Drill Bits for Rotary Hammers
Also known as A-taper bits, these fit rotary hammers with a taper-shank chuck. Drill holes using simultaneous rotary and hammering action to break masonry material into tiny granules. This type of bit drills faster and penetrates material with less pressure than rotary-only bits. Also called percussion or impact bits.

Chip-Clearing Drill Bits for Wood
An open spiral-flute design clears chips quickly, so these bits can bore smooth, deep holes through construction lumber, railroad ties, and utility poles. Also known as pole or ship auger bits.
Tapered square/round-shank drill bits have a tapered square shank that can be cut off to expose a round shank.
