The Var Tools 41mm ream/facing cut is a professional-grade workshop tool designed for precise preparation of bicycle head tubes and related frame interfaces. Built for use with compatible reaming and facing systems, this cutter allows mechanics to accurately machine surfaces so that headsets seat perfectly square and true. By combining reaming and facing in one operation, it helps ensure optimal bearing alignment, smoother steering performance, and reduced wear over time. This tool is ideal for experienced home mechanics and professional workshops who demand consistent, repeatable results on high-end frames.
Engineered to work with standard shop reaming and facing handles, the Var 41mm ream/facing cutter is typically used on frames that require a 41mm internal diameter, such as many modern integrated or semi-integrated headset standards. Its carefully machined cutting edges are designed to remove material cleanly and efficiently, minimizing chatter and helping to protect the integrity of the frame. Whether you are building a new bike from the frame up or overhauling a well-ridden machine, this cutter is a key component in achieving precise, reliable headset installation.
