General description The Irwin long auger wood drill bits are designed for efficient and precise boring in all types of wood, offering superior performance. They feature a single spur cutting edge that scribes the circumference of the hole for a smoother quality finish. The hexagon shank prevents slipping in a drill chuck or bit extension, while the solid center provides extra rigidity during boring. The self-feeding screw point allows for faster boring in both soft and hard woods, and the fully hardened body from tip to shank ensures extra durability.
