Irwin Wood Auger Drill Bit

The Irwin IRW10502760 is a 17mm diameter auger drill bit with a 191mm overall length, offering a specialist size for specific structural fastener requirements and heavy-duty construction applications. This less common diameter is particularly useful for certain bolt specifications, specialist structural fixings, and applications where precise hole sizing between standard diameters is required. Engineered for all general wood boring, this auger bit delivers superior performance with its precision-sized large-diameter cutting edge. The single spur cutting edge scribes the circumference of the hole for a smoother quality finish, ensuring specialist structural fasteners achieve proper seating and maximum holding power, whilst the hexagon shank prevents slipping in drill chucks or bit extensions under high torque. The solid centre provides extra rigidity whilst boring, maintaining accuracy for structural applications where dimensional precision is critical. The self-feeding screw point provides faster boring in both soft and hard woods without compromising hole quality, and the fully hardened body from tip to shank provides extra durability for demanding construction environments.
