Description
The Irwin IRW10502774 is a 25mm diameter auger drill bit with a 191mm overall length, offering a substantial size for major structural applications, heavy construction fasteners, and large-scale engineering projects. This larger diameter is widely used for substantial structural bolts, major fixings, and applications requiring significant through-holes in heavy timber construction and 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 requirements, whilst the hexagon shank prevents slipping in drill chucks or bit extensions under the considerable torque generated when boring 25mm diameter holes. The solid centre provides extra rigidity whilst boring, essential for maintaining accuracy with this substantial diameter where cutting forces are high and straightness is critical. The self-feeding screw point provides faster boring in both soft and hard woods, significantly improving productivity on major structural projects, and the fully hardened body from tip to shank provides extra durability under the demanding conditions of large-diameter structural work. Features and Benefits: • 25mm diameter perfect for major structural and heavy engineering applications • 191mm length suitable for substantial construction work • Single spur cutting edge delivers clean, structural-quality large holes • Solid centre critical for accuracy under high structural cutting forces • Self-feeding design significantly improves efficiency in large-diameter boring • Fully hardened construction ensures durability in demanding structural use Specifications: Diameter (mm): 24 Overall Length (mm): 191 Working Length (mm): 126 Pack Qty.: 1
