Wood Auger Drill Bit 30mm 400mm

The Irwin IRW10502781 is a long series 30mm diameter auger drill bit with an extended 400mm overall length, specifically engineered for deep boring applications requiring this major structural hole diameter. This specialist bit is essential for substantial structural timber work, major services installation through thick beams, heavy engineering applications, and major construction projects where both large diameter and exceptional reach are absolutely critical. Designed for all general wood boring, this long auger bit offers superior performance under the most demanding large-diameter structural conditions. The single spur cutting edge scribes the circumference of the hole for a smoother quality finish throughout the full depth of major bores, whilst the hexagon shank prevents slipping in drill chucks or bit extensions during prolonged, heavy-duty structural drilling operations. The solid centre provides extra rigidity whilst boring, absolutely critical for maintaining straightness when drilling 30mm diameter holes at considerable depth through major structural timbers. The self-feeding screw point provides faster boring in both soft and hard woods whilst maintaining tracking accuracy in substantial deep bores, and the fully hardened body from tip to shank provides extra durability under the considerable forces encountered during deep, large-diameter structural work.

Features and Benefits:

• 30mm diameter with 400mm length for major deep structural applications
• Long series design tackles the most substantial structural timber work
• Single spur cutting edge maintains structural finish quality in deep large holes
• Solid centre essential for preventing deflection under substantial forces at depth
• Self-feeding design maintains accuracy whilst reducing considerable operator fatigue
• Fully hardened body ensures maximum reliability in the most demanding structural applications
