About this product
This Irwin auger drill bit measures 20mm in diameter with an overall length of 191mm and a working length of 126mm, making it suited to heavy-duty joinery and structural fixings such as large coach screws and bolts where big clearance holes are needed in timber.
A single spur cutting edge scribes the hole's circumference for a smooth finish, while the solid centre keeps the bit rigid and straight under cutting forces. The self-feeding screw point speeds up boring in soft and hard woods, and the hexagon shank resists slipping in the chuck. The body is fully hardened from tip to shank for durability.
