Irwin Blue Groove Power Wood Drill Bit

The 22mm Irwin Blue Groove Power wood drill bit is designed for drilling large diameter holes required for substantial pipe work, heavy cable bundles and sizeable fixtures. This diameter is particularly favoured by plumbers working with larger waste pipes and electricians installing multiple cable runs. This 22mm bit features IRWIN's revolutionary bi-metal technology, making it the world's first wood drill bit capable of cutting through nail-embedded wood without locking or breaking. The bi-metal construction combines a high-speed steel cutting edge that delivers exceptional durability and nail-cutting capability, with a carbon steel body that provides the flexibility needed to prevent catastrophic failure during demanding applications. Equipped with a self-feeding tip that pulls the bit through materials efficiently, plus three precision cutting edges for enhanced chip removal, this 22mm variant ensures fast drilling and consistently clean holes. It's particularly suited to commercial installations and renovation work where encountering hidden nails is common.
