Wood Auger Drill Bit 38mm 240mm

The Irwin IRW10502787 is a 38mm diameter auger drill bit with a 240mm overall length, offering a substantial size for major structural applications, heavy engineering fasteners, and large-scale construction projects. This larger diameter is used for substantial structural requirements, major engineering fixings, and specialist applications requiring very large through-holes in heavy timber construction and major engineering work. Engineered for all general wood boring, this auger bit delivers superior performance in demanding large-diameter structural applications. The single spur cutting edge scribes the circumference of the hole for a smoother quality finish suitable for major structural and engineering requirements, whilst the hexagon shank prevents slipping in drill chucks or bit extensions under the considerable torque generated when boring 38mm diameter holes. The solid centre provides extra rigidity whilst boring, essential for maintaining accuracy with this substantial diameter where cutting forces are very high. The self-feeding screw point provides faster boring in both soft and hard woods, significantly improving productivity on major structural and engineering projects, and the fully hardened body from tip to shank provides extra durability under the demanding conditions of large-diameter structural boring operations.

Features and Benefits:

• 38mm diameter perfect for major structural and heavy engineering applications
• 240mm extended length suitable for substantial construction work
• Single spur cutting edge delivers clean, structural-quality large holes
• Solid centre critical for accuracy under very high structural cutting forces
• Self-feeding design significantly improves efficiency in large-diameter boring
• Fully hardened construction ensures durability in the most demanding structural use
