Prevent clogs that wear the bit and slow down drilling when it gets jammed. The flutes on these bits have an open design that pulls chips out of the hole faster than standard spiral flutes. Also known as pole or ship auger bits, they are used to cut deep holes through lumber, railroad ties, and utility poles.

Quick-Change Hex Shank—Switch bits instead of tools. These simplify jobs by snapping directly into power screwdrivers, drills, and other tools that accept a _1/4" hex shank.

Round Shank—Fit in the chuck of drill presses and portable drills.

Hex Shank—Secure in chucks that accept a hex shank. You can also cut the bit to expose a _1/2" round shank for use in other tools.

Tapered-Square Shank—Use with manual hand drills. You can cut off the square portion to expose a round shank to fit other tools.

Screw Point—Draws the bit into the material without the need to apply a lot of pressure.

Black-Oxide Steel—The dark finish reduces friction to clear chips more quickly than uncoated bits.

Nonstick-Coated Steel—Chips won’t stick to the bit, even when drilling in material that contains sap or glue.
