Irwin 4X Blue Groove Long Flat Wood Drill Bit 16mm 400mm

Designed for medium to larger diameter drilling in timber construction, the Irwin Blue Groove 4X Long Flat Bit delivers exceptional speed and clean, accurate holes. Its extended 400mm length provides the reach needed for deep, precise boring through studs, joists, and framing timbers, making this bit a reliable workhorse for professional builders and keen DIYers alike.

- 4X faster drilling speed compared to standard flat bits, with a patented blue-groove design that removes waste material more efficiently

- 16mm diameter offers the ideal balance for structural timber work, plumbing, and electrical runs

- 400mm usable length allows deep, accurate drilling through multiple layers of timber without repositioning

- Fully hardened full-length body reduces flex and extends bit life, even in tough, knotty timber

- Self-feeding precision-ground point pulls the bit steadily into the workpiece for cleaner starts and less operator effort

- Hex shank prevents slipping in the chuck for consistent torque transfer and safety

- Works with both corded and cordless drills, suitable for site and workshop use

Trusted by tradespeople for its durability and drilling performance, this 16mm x 400mm Irwin bit is a practical addition to any tool kit.
