Wood Auger Drill Bit 35mm 400mm

The Irwin IRW10502785 is a long series 35mm 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 represents one of the larger sizes available and is essential for substantial structural timber work, major engineering applications, heavy services installation through thick beams, and major construction projects where both very large diameter and extended reach are 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 sessions. The solid centre provides extra rigidity whilst boring, absolutely critical for maintaining straightness when drilling 35mm 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 holes, and the fully hardened body from tip to shank provides extra durability under the considerable forces generated during deep, large-diameter structural work.

Features and Benefits:

• 35mm diameter with 400mm length for major deep structural applications
• Long series design essential for the most substantial structural work
• Single spur cutting edge maintains structural quality throughout deep large holes
• Solid centre prevents deflection under very high forces at depth
• Self-feeding design maintains control whilst reducing substantial operator fatigue
• Fully hardened body ensures maximum reliability in the most demanding applications
