Irwin IRWIN® Wood Auger Drill Bit Long Series 26 x 400mm 10502777

This Irwin long series auger drill bit has a 26mm diameter and 400mm overall length, suited to deep boring in major structural timber, heavy beams and posts where both large diameter and extended reach are needed. Designed for general wood boring, it offers a strong, controlled cut throughout the full depth of the bore.

A single spur cutting edge scribes the hole's circumference for a smoother finish, while the solid centre adds rigidity to help prevent deflection at depth. The self-feeding screw point speeds up boring in soft and hard woods while keeping the bit tracking accurately, and the hexagon shank resists slipping in drill chucks or bit extensions. The body is fully hardened from tip to shank for added durability.
