A wood boring auger is a spiral-shaped drill bit that is designed specifically for boring clean, deep holes in wood.
This is the standard type of auger bit used in DIY, and can be used with hand drills, power drills and drill presses.
Stubby wood augers can be used in confined spaces where it is not possible to fit a regular bit.
Although less popular than some other woodworking bits in the home, augers are often used by construction workers, where drilling to a greater depth is more often required.
