Max. bottom bracket shell diameter: 44mm
Note: Use the correct 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.
Make sure you use a suitable cutting oil for the material being faced!
