About this product
This Irwin long series auger bit is a 22mm diameter wood drilling bit with a 400mm overall length, suited to deep boring through structural timber, thick beams and heavy posts where both large diameter and extended reach are needed. It is designed for general wood boring where a long reach is required.
A single spur cutting edge scribes the hole's circumference for a smoother finish, while the hexagon shank prevents slipping in the drill chuck or bit extension. The solid centre adds rigidity to reduce deflection at depth, and the self-feeding screw point speeds boring in soft and hard woods while keeping accurate tracking. The body is fully hardened from tip to shank for durability.
