Wood Auger Drill Bit 10mm 400mm

The Irwin IRW10502745 is a long series 10mm diameter auger drill bit with an extended 400mm overall length, designed for deep boring applications where substantial hole diameter and extended reach are both required. This specialist bit is perfect for timber frame construction, deep fence post preparation, running services through thick walls, and any structural work requiring larger diameter holes at considerable depth. Designed for all general wood boring, this long auger bit offers superior performance even under demanding conditions. The single spur cutting edge scribes the circumference of the hole for a smoother quality finish throughout the full depth of the bore, whilst the hexagon shank prevents slipping in drill chucks or bit extensions during extended drilling sessions. The solid centre provides extra rigidity whilst boring, essential for maintaining straightness and accuracy with longer bits drilling larger diameter holes. The self-feeding screw point provides faster boring in both soft and hard woods whilst maintaining control, and the fully hardened body from tip to shank provides extra durability under the substantial forces generated during deep, large-diameter boring.
