Chip-Clearing Drill Bits for Wood
Tapered Square/Round Shank
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.
