About this tool

The Faithfull 20mm Tri-Point Speed Auger Bit with 159mm overall length is an excellent choice for drilling holes for standard waste pipes, larger electrical cable runs, and substantial dowel joints in all types of timber. This 20mm diameter is particularly popular for kitchen and bathroom installations where plumbing work requires clean, accurate holes. The innovative tri-point design with three spurs and cutting edges creates perfectly round 20mm holes whilst significantly reducing the risk of binding in the workpiece. Three flutes offer efficient waste removal, making this bit much faster than traditional alternatives when drilling through both softwood and hardwood materials. A self-feeding screw tip enables accurate centring and actively pulls the bit through the wood, reducing user fatigue during extended use. Precision machined from high-quality carbon steel with ground and honed cutting edges for long-lasting performance. The quick-release 1/4in hex shank is impact rated, ensuring compatibility with impact drivers as well as all other corded and cordless drills.
