Irwin Wood Auger Drill Bit

The Irwin IRW10502747 is an 11mm diameter auger drill bit with a 191mm overall length, offering a specialist size for specific fastener requirements and custom joinery applications. This less common diameter is particularly useful when working with metric fittings, certain bolt sizes, and bespoke furniture work where standard diameters don't quite meet requirements. Engineered for all general wood boring, this auger bit delivers superior performance with its precision-sized cutting diameter. The single spur cutting edge scribes the circumference of the hole for a smoother quality finish, ensuring fasteners and fittings seat properly, whilst the hexagon shank prevents slipping in drill chucks or bit extensions for consistent results. The solid centre provides extra rigidity whilst boring, maintaining accuracy for precision-fit applications. 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 professional trade use.
