About this product
This Irwin auger drill bit measures 40mm in diameter with an overall length of 240mm and a working length of 175mm, making it suited to large-scale boring work in heavy timber and structural construction. It is designed for general wood boring, offering strong performance where large-diameter through-holes are required.
A single spur cutting edge scribes the hole's circumference for a smoother finish, while the hexagon shank helps prevent slipping in a drill chuck or bit extension. The solid centre adds rigidity during boring, and the self-feeding screw point speeds up boring in both soft and hard woods. The body is fully hardened from tip to shank for added durability.
