Irwin Wood Auger Drill Bit

The Irwin IRW10502756 is a 15mm diameter auger drill bit with a 191mm overall length, offering a versatile size for substantial joinery, construction fasteners, and medium to large cable routing applications. This diameter bridges the gap between standard and large boring requirements, making it ideal for a wide range of heavy-duty woodworking tasks. Engineered for all general wood boring, this auger bit delivers superior performance across demanding applications. The single spur cutting edge scribes the circumference of the hole for a smoother quality finish that's suitable for both functional and visible work, whilst the hexagon shank prevents slipping in drill chucks or bit extensions under significant drilling loads. The solid centre provides extra rigidity whilst boring, maintaining accuracy even when working with challenging grain patterns or dense hardwoods. The self-feeding screw point provides faster boring in both soft and hard woods, reducing drilling time and operator fatigue on larger projects, and the fully hardened body from tip to shank provides extra durability for sustained professional use.
