Tool Cyclus Tools for tapping and facing BSA bottom bracket shells (720149)

A professional Cyclus Tools tool designed to recut BSA bottom bracket threads and face the bottom bracket shell.

Features

• Designed for recutting bottom bracket shell threads and facing the shell.
• After the thread has been recut, the cutting tool is disengaged and the facing tool is used. The tool does not need to be reclamped, allowing 100% facing of the bottom bracket shell.
• Both machining operations are combined in one process, so changing or modifying the tools is not necessary.
• Accurately faced surfaces ensure that the faces are parallel to each other and square to the threads. This is especially important for bottom brackets with external cups, such as Campagnolo Ultra Torque and Shimano Hollowtech II.
• The precise guide ensures parallel faced shell surfaces.

Markings on the tool

Letters or marks on the tool refer to the tool itself. “R” indicates a conventional thread and a clockwise direction of rotation. “L” indicates a counterclockwise direction of rotation. These markings do not indicate the side of the bicycle on which the tool is used, as there is no fixed reference system for this.
