Irwin Wood Auger Drill Bit

The Irwin IRW10502758 is a long series 16mm diameter auger drill bit with an extended 400mm overall length, engineered for deep boring applications requiring this substantial hole size. This specialist bit is indispensable for deep structural work, major services installation through thick beams, heavy construction post holes, and any application requiring large-diameter holes at considerable depth. Designed for all general wood boring, this long auger bit offers superior performance in the most challenging deep-hole scenarios. The single spur cutting edge scribes the circumference of the hole for a smoother quality finish throughout the entire bore depth, whilst the hexagon shank prevents slipping in drill chucks or bit extensions during prolonged, heavy-duty drilling operations. The solid centre provides extra rigidity whilst boring, absolutely essential for preventing deflection when drilling large diameter holes at extended depths. The self-feeding screw point provides faster boring in both soft and hard woods whilst maintaining tracking accuracy, and the fully hardened body from tip to shank provides extra durability under the substantial forces encountered during deep, large-diameter structural work.
