Irwin Wood Auger Drill Bit

The Irwin IRW10502754 is a 14mm diameter auger drill bit with a 191mm overall length, perfectly sized for larger fastener applications, substantial cable routing, and heavy-duty construction work. This diameter is commonly specified for larger coach bolts, structural fixings, and anywhere significant clearance holes are required in timber framing and joinery. Engineered for all general wood boring, this auger bit delivers superior performance in robust construction applications. The single spur cutting edge scribes the circumference of the hole for a smoother quality finish that's ready for immediate fastener installation, whilst the hexagon shank prevents slipping in drill chucks or bit extensions even when drilling dense hardwoods. The solid centre provides extra rigidity whilst boring, essential for maintaining accuracy with larger diameter bits where cutting forces are substantial. The self-feeding screw point provides faster boring in both soft and hard woods, significantly improving productivity on site, and the fully hardened body from tip to shank provides extra durability under the demanding conditions typical of construction work.
