Holemaking and Drilling

Durable hardened cutting edge for long life in tough materials, including nail-embedded wood. Fully-forged bit for maximum durability. Wide flutes for maximum chip removal and less binding. Aggressive screw-pitch for faster drilling.

Solid centre design provides extra rigidity while boring. Wide lands keep the bit straight as it bores through the hole. The flutes are ground behind the lands to funnel chips to the inside of the bit and away from the outside diameter, producing a...
