"Cyclus Tools Cutting & milling tool for BSA threads is a professional tool specifically designed for recutting work on the bottom bracket thread and for milling work on the bottom bracket shell.
After you have recut the thread, the cutting tool is disengaged and the face milling tool is used. You don't need to re-clamp the tool, ensuring 100% face milling of the bottom bracket shell treads. especially developed for recutting threads and facing of the bottom bracket housing.
It combines the two operations in one process so changing or modification of the tools isn't 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
. two part tool which insert together, provides an exact guide to cut parallel faced shells
3 steps:
Cut the bb thread
Disconnect the cutting tool
Face bb shells
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 - counterclockwise.
It does not refer to the side of the bicycle, because there is no fixed reference system here!" Part Number: 720149 Barcode: 8590831360012 Product Code: CYC 720149
