About this product
This Irwin auger drill bit is a long series design for deep boring in wood, suited to structural work, deep post holes and running services through thick beams. It has a 12mm diameter, 400mm overall length and a working length of 323mm.
A single spur cutting edge scribes the hole's circumference for a smoother finish, while the solid centre adds rigidity to help maintain accuracy at depth. The self-feeding screw point speeds up boring in both soft and hard woods while keeping the bit on track, and the hexagon shank helps prevent slipping in a drill chuck or bit extension. The body is fully hardened from tip to shank for added durability.
