About this product
This Irwin auger drill bit measures 38mm in diameter with an overall length of 240mm and a working length of 175mm, suited to large-diameter wood boring for structural and heavy engineering applications.
A single spur cutting edge scribes the hole's circumference for a smoother finish, while the solid centre adds rigidity to maintain accuracy under the high cutting forces this diameter generates. The hexagon shank helps prevent slipping in a drill chuck or bit extension.
The self-feeding screw point speeds up boring in both soft and hard woods, and the fully hardened body from tip to shank is designed to withstand demanding, large-diameter boring work.
