Irwin IRWIN® Blue Groove 6X Wood Drill Bit 25 x 165mm 10506624

The Irwin 6X Blue Groove 25mm Wood Drill Bit is perfectly sized for drilling large diameter holes in timber applications, making it essential for major plumbing installations, substantial cable runs, and heavy-duty carpentry work. This 25mm variant provides the drilling capacity needed for larger pipework, significant fixings, and structural applications where larger bore holes are required. Delivering six times faster drilling penetration than standard flat bits, this 25mm drill bit dramatically reduces time spent on substantial drilling tasks. The advanced Tri-Flute design ensures efficient chip ejection, preventing clogging and maintaining consistent performance even during extended use in deep holes. A full screw tip provides positive engagement and smooth pull-through, whilst precision-ground cutting spurs create professionally clean holes with minimal breakout on both entry and exit points. The tapered flute geometry significantly reduces binding during operation, allowing controlled drilling even in challenging hardwoods and dense materials. Heat-treated construction ensures this 25mm drill bit retains its cutting edge and delivers reliable performance throughout demanding professional use.
