Irwin Wood Auger Drill Bit

The Irwin IRW10502752 is a long series 13mm diameter auger drill bit with an extended 400mm overall length, designed for deep boring applications where this specific diameter is required. This specialist bit is invaluable for deep structural work, extended services installation, and any application requiring 13mm diameter holes at considerable depth where standard length bits cannot reach. Designed for all general wood boring, this long auger bit offers superior performance even in challenging deep-hole applications. The single spur cutting edge scribes the circumference of the hole for a smoother quality finish along the entire bore length, whilst the hexagon shank prevents slipping in drill chucks or bit extensions throughout extended drilling operations. The solid centre provides extra rigidity whilst boring, critical for maintaining dimensional accuracy when drilling at depth with this diameter. The self-feeding screw point provides faster boring in both soft and hard woods whilst keeping the bit tracking straight, and the fully hardened body from tip to shank provides extra durability under the demanding conditions of deep hole work.
