CYCLUS TOOLS bottom bracket shell facing cutter. With the Cyclus Tools cutter you can clean up (face) the bottom bracket shell faces to make them perfectly parallel to each other. This enables the bottom bracket to be correctly mounted and the bearings to be aligned.max. cutter diameter: 9mmmax. bottom bracket shell diameter: 44mmNote:Use the suitable guide bushing according to the thread (BSA / ITAL / French). In order to avoid overloading and / or slipping.It is necessary to apply uniform pressure on the cutter with the help of the guide, the spring and the threaded sleeve.Note: Make sure you use a suitable cutting oil for the material being faced!

CYCLUS TOOLS complete bottom bracket threading tool BSA (1,370" x 24 tpi).With the Cyclus Tools Threader for BSA (1,370" x 24 tpi) you'll generate an optimal concentric bottom bracket thread. Insert both sides of the threader tap simultaniously to avoid canting and damage to the existing threadInner diameter of the scabbard holder: 16mm.  Attention: Letters or marks on the tool refer to the tool itself, not the left or right side of the bicycle (i.e. "R" on one side of the tool is for chasing a classic right handed thread, so the tool must be turned to the right (clockwise). The "L" side of the tool is for the left hand thread of the bottom bracket shell, which must be turned to the left counterclockwise)Use a cutting oil suitable for the material to be machined.

With the Cyclus Tools Threader Professional for BSA (1,370" x 24 tpi) you'll generate optimal concentricity of the bottom bracket's thread. Insert both sides of the threader simultanly to avoid any canting. The usage of an appropriate cutting oil is necessary.Attention: letters and marks on the tool refer to the tool itself, not the frame (e.g. "R" means you have to turn the tool to the right, "L" means turn to the left!)

Product DescriptionCyclus 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    tool change is not required    exact guide ensures parallel faced 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 is not meant the application side with the bicycle, because there is no fixed reference system here!
