This 19mm x 400mm Long Series Faithfull Combination Auger Bit delivers substantial drilling capacity with extended reach, making it an essential tool for major deep boring applications. The combination of 19mm diameter and 400mm length enables drilling through thick structural members, deep wall sections, or multiple timbers where larger services need routing. The 19mm diameter provides ample clearance for substantial plumbing, larger electrical installations, and heavy-duty mechanical fixings, whilst the extra long length ensures you can complete deep boring tasks that standard bits simply cannot reach. Machined from high quality carbon steel, this bit is specifically engineered to maintain rigidity and resist deflection even under the demanding conditions of large diameter, deep drilling. The pitched screw point delivers consistent self-feeding action throughout the entire drilling depth, reducing operator fatigue whilst maintaining accuracy. The wide flat spiral design is absolutely crucial at this combination of diameter and length, ensuring straight tracking over extended distances whilst efficiently evacuating the substantial volume of waste material generated. Suitable for timber, plywood, MDF and blockwood, this extra long auger operates effectively in either hand or power drills at low speeds. The carbon steel construction allows for resharpening using a hand file.
