Irwin Wood Auger Drill Bit

The Irwin IRW10502751 is a 13mm diameter auger drill bit with a 191mm overall length, offering a specialist size for specific engineering and construction fastener requirements. This diameter is particularly useful for certain bolt specifications, specialist fittings, and applications where precise hole sizing between standard diameters is required for optimal fastener performance. Engineered for all general wood boring, this auger bit delivers superior performance with its precision-engineered cutting diameter. The single spur cutting edge scribes the circumference of the hole for a smoother quality finish, ensuring specialist fasteners and fittings achieve proper seating and holding power, whilst the hexagon shank prevents slipping in drill chucks or bit extensions. The solid centre provides extra rigidity whilst boring, maintaining accuracy for precision-critical applications. The self-feeding screw point provides faster boring in both soft and hard woods without compromising dimensional accuracy, and the fully hardened body from tip to shank provides extra durability for professional trade environments.
