Cutting & Facing Tool For BSA * Art Nr:720149 * EAN Code: 8590831360012 Cutting & milling tool for BSA threads is a professional tool specifically designed for re-cutting work on the bottom bracket thread and for milling work on the bottom bracket shell. After you recut the thread, the cutting tool is disengaged and the face milling tool is used. You do not need to re-clamp the tool, ensuring 100% face milling of the bottom bracket shell treads. Specially developed for re-cutting threads and facing the bottom bracket housing. Combining the two operations into one easy process so changing or modifying the tool is not necessary. Accurate facing of bottom bracket faces means the shells will be 100% parallel to each other and square to the threads. This is very important for bottom brackets with outer cups e.g. Campagnolo Ultra Torque, Shimano Hollowtech II. **Benefits:** * Two machining processes in one. Cuts the thread of the bottom bracket and faces the shell in one action without changing tools. * Saves space, time and money as only one tool is needed. **Please note:** Letters or marks applied to the tool always refer to the tool itself. I.e. if an R is applied to one side, then this is a classic thread with the direction of rotation to the right - clockwise. If an L is applied, the direction of rotation is to the left - counter clockwise. It does not refer to the side of the bicycle, because there is no fixed reference system here!
