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.

These jobbers'-length bits have the rigidity and length required for most applications.

The parabolic spiral flutes lift chips out of the hole, reducing clogging and improving coolant flow.

Cobalt steel bits are heat resistant and maintain their sharp edges when drilling hard material. They are for use in both hand-held drilling and machine-tool applications.

Designed to lift chips out of the hole, these bits reduce clogging and improve coolant flow.
