Offering 6 times faster drilling penetration than a standard flat bit, the Irwin 3 Piece 6X Auger Bits are ideal for drilling wood - with their ‘Tri-Flute’ design allowing for faster chip ejection! Their full screw tips also ensure ease of use and pull through, while the cutting spins help to minimise breakout to produce cleaner holes! For extra durability, the drill bits are also heat treated.
