About this product
This Irwin long series auger drill bit has a 30mm diameter and an overall length of 400mm, designed for deep boring in general wood, including thick beams and substantial structural timber. Its length and diameter make it suited to jobs where both reach and a large hole size are needed.
The bit has a single spur cutting edge that scribes the hole's circumference for a smoother finish, and a solid centre that adds rigidity to help keep the hole straight when boring deep. The self-feeding screw point speeds up boring in both soft and hard woods, while the hexagon shank resists slipping in a drill chuck or bit extension. The body is fully hardened from tip to shank for added durability.
