About this product
This Faithfull Long Series Combination Auger Bit measures 10mm in diameter and 400mm in length, designed for deep boring where standard length bits cannot reach. It suits drilling through thick timbers, multiple joists, and other jobs needing extra reach, including cable routing and deep pilot holes.
Machined from high quality carbon steel, it has a pitched screw point for accurate starting and a wide flat spiral that gives stability, straight tracking and efficient waste removal, helping to prevent binding at depth. It can be used in timber, plywood, MDF and blockwood, works in either a hand or power drill at low speeds, and can be resharpened with a hand file.
