Irwin Wood Auger Drill Bit 14mm 400mm

The Irwin IRW10502755 is a long series 14mm diameter auger drill bit with an extended 400mm overall length, specifically designed for deep boring applications requiring this substantial hole diameter. This specialist bit is essential for structural timber work, deep post installations, major services routing through thick beams, and heavy construction applications where both large diameter and extended reach are necessary. Designed for all general wood boring, this long auger bit offers superior performance under the most demanding conditions. The single spur cutting edge scribes the circumference of the hole for a smoother quality finish throughout the full bore depth, whilst the hexagon shank prevents slipping in drill chucks or bit extensions during extended, heavy-duty drilling sessions. The solid centre provides extra rigidity whilst boring, absolutely critical for maintaining straightness and accuracy when drilling large diameter holes at considerable depth. 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 in deep, large-diameter construction work. Features and Benefits: • 14mm diameter with 400mm length for substantial deep structural boring • Long series design essential for thick beam and heavy timber work • Single spur cutting edge maintains professional finish at full depth • Solid centre prevents deflection under high forces at depth • Self-feeding design maintains accuracy whilst reducing operator fatigue • Fully hardened body delivers reliability in the toughest applications Specifications: Diameter (mm): 14 Overall Length (mm): 400 Working Length (mm): 335 Pack Qty.: 1
