Irwin Wood Auger Drill Bit – 10502778

The Irwin IRW10502778 is a 26mm diameter auger drill bit with a 240mm overall length, offering an extended length option for this substantial diameter. This specialist variant combines the benefits of a larger structural hole size with additional reach beyond standard lengths, making it ideal for thicker timber work, deeper structural applications, and situations where 191mm is too short but 400mm is excessive. Engineered for all general wood boring, this auger bit delivers superior performance in demanding large-diameter applications requiring additional depth. The single spur cutting edge scribes the circumference of the hole for a smoother quality finish suitable for major structural requirements, whilst the hexagon shank prevents slipping in drill chucks or bit extensions under the considerable torque generated when boring 26mm diameter holes. The solid centre provides extra rigidity whilst boring, essential for maintaining accuracy with this substantial diameter at the extended length. The self-feeding screw point provides faster boring in both soft and hard woods, improving efficiency on structural projects, and the fully hardened body from tip to shank provides extra durability under the demanding conditions of large-diameter structural boring.
