Irwin Wood Auger Drill Bit

The Irwin IRW10502765 is a long series 19mm diameter auger drill bit with an extended 400mm overall length, designed for deep boring applications requiring this substantial hole diameter. This specialist bit is indispensable for major structural work, deep services installation, heavy post preparation, and construction applications where both large diameter and exceptional reach are necessary.

Designed for all general wood boring, this long auger bit offers superior performance in the most challenging large-diameter 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 structural drilling sessions.

The solid centre provides extra rigidity whilst boring, absolutely essential for preventing deflection when drilling substantial diameter holes at extended depths. The self-feeding screw point provides faster boring in both soft and hard woods whilst keeping the bit tracking accurately through deep bores, and the fully hardened body from tip to shank provides extra durability under the substantial forces encountered during deep, large-diameter structural operations.

Features and Benefits:

• 19mm diameter with 400mm length for substantial deep structural boring
