What is an auger bit?

An auger bit is a spiral-shaped drill bit that is designed to drill deep holes in wood.

Auger bits excel at removing waste material from a borehole, meaning they are unlikely to get jammed inside a workpiece.

Just like some of the other specialist wood bits, auger bits have a sharp point at the centre of their tip to ensure that holes can be drilled with precision. Most have a screw thread on them that helps to pull the bit through the wood with ease.

Augers have been in use for centuries, and a variety of different designs of auger bit exist for use in DIY and construction.
