Irwin Blue Groove Power Wood Drill Bit 25mm

The 25mm Irwin Blue Groove Power wood drill bit is perfect for drilling large diameter holes required for substantial waste pipes, ventilation ducts and heavy-duty fixtures. This size is essential for professional tradesmen working on commercial installations and major domestic projects. Featuring IRWIN's pioneering bi-metal technology, this 25mm bit delivers unrivalled performance that standard flat bits cannot match, particularly when drilling through nail-embedded wood. The innovative construction combines a high-speed steel cutting edge that provides exceptional durability and allows nail cutting without failure, with a flexible carbon steel body that prevents the bit from locking or breaking under stress. The self-feeding tip actively draws the bit through timber materials, significantly reducing the effort required from both drill and operator, whilst three precision-ground cutting edges ensure rapid chip removal for faster drilling and consistently clean holes. This 25mm variant is particularly effective for installing larger waste pipes, ventilation systems and architectural metalwork.
