Fast-Cutting Smooth-Finish Drill Bits for Wood
![]() |
Quick-Change Hex Shank Screw Point |
Not only do these bits bore holes faster than standard smooth-finish bits, they create less friction and heat buildup to last longer. The spurred teeth have a long life, but they're less effective at guiding the bit so cuts on angled and overlapping holes tend to be rougher. Also known as multispur bits.
Black Oxide—The dark finish increases wear resistance and reduces friction to improve chip flow, so these bits can last 50% longer than uncoated bits.
