Irwin IRWIN® Wood Auger Drill Bit Long Series 16 x 400mm 10502758

This Irwin long series auger bit is a 16mm diameter wood drill bit with a 400mm overall length, designed for deep boring through thick structural timbers, beams and posts where extended reach is needed. It suits general wood boring but is particularly useful for deep or large-diameter holes, such as services installation through heavy sections.

The single spur cutting edge scribes the hole's circumference for a smooth finish, while the solid centre adds rigidity to resist deflection when boring deep holes. A self-feeding screw point speeds up boring in both soft and hard woods while keeping the bit on track, and the hexagon shank stops slipping in a chuck or bit extension. The body is fully hardened from tip to shank for added durability under heavy use.
