Irwin Wood Auger Drill Bit

The Irwin IRW10502764 is a 19mm diameter auger drill bit with a 191mm overall length, offering a substantial size for major construction fasteners, large-scale joinery, and heavy structural applications. This diameter is particularly useful for substantial bolts, major fixings, and applications requiring significant clearance holes in heavy timber construction. Engineered for all general wood boring, this auger bit delivers superior performance in demanding large-diameter applications. The single spur cutting edge scribes the circumference of the hole for a smoother quality finish suitable for structural work, whilst the hexagon shank prevents slipping in drill chucks or bit extensions under the high torque generated when boring larger diameter holes. The solid centre provides extra rigidity whilst boring, maintaining straightness and accuracy despite the substantial cutting forces involved. The self-feeding screw point provides faster boring in both soft and hard woods, making large-diameter drilling more manageable and less fatiguing, and the fully hardened body from tip to shank provides extra durability for sustained heavy-duty use.
