About this product
This Irwin auger drill bit has an 18mm diameter and an overall length of 191mm, with a working length of 126mm, making it suited to larger structural fixings, coach bolts and heavy-duty boring in timber framing and joinery.
A single spur cutting edge scribes the circumference of the hole for a clean, smooth finish, while the solid centre adds rigidity to maintain accuracy under the greater cutting forces involved with this diameter. The self-feeding screw point speeds up boring in both soft and hard woods.
The hexagon shank resists slipping in a drill chuck or bit extension, and the body is fully hardened from tip to shank for added durability during demanding use.
