Irwin Blue Groove 6X Long Wood Drill Bit 18 x 400 mm

The Irwin Blue Groove 6X Drill Bits are designed for drilling wood with significantly faster penetration than standard flat bits. Featuring a Tri-Flute design, they promote faster chip ejection, while full screw tips aid ease of use and pull through. The cutting spurs deliver clean holes with minimal breakout, and the tapered flute helps reduce binding. Heat treatment adds durability to the bits, making them suitable for challenging drilling tasks. These are extra-long bits, measuring 40 cm (16 in) in length, making them well-suited for drilling through walls, ceilings, and floors. With a diameter of 18 mm and a working length of 10 mm (4 in), the overall length is 400 mm (16 in). This combination of length, design features, and toughness makes them a practical choice for applications requiring access through multiple materials and tight spaces.
