Does anyone have experience with Bottom Bracket Tap/Facing sets?
Bottom Bracket Taps and Facing tools are an expensive and highly specialized tool. As a workshop, owning them and knowing when and how to use them properly, is one of the key signs of a professional shop.

Many new frames are moving to design without threads, but these tools will continue to be valuable for years to come.

These are the brands I'm familiar with, and recommend:


The Park Tool set is quality, and durable. For a set of taps and facing blades that will be durable, and also are likely to maintain compatibility with future similar tool sets from Park, it's hard to go wrong there.





The Campagnolo set has been the quality standard for shop use for 30 years at least. I know of one shop that's had theirs in continuous use for at least that long. You do pay for it, and the Campy tap set is a separate tool.


      


The Cylus Tap sets are excellent as well, although durability is yet to be proven. They are a more complicated machine, which allows a speedier, and very well done, job to be performed. It also allows for more things to break on their system. This is an impression I have only. I have not seen one fail. It does require a separate tool for english and italian BB's, and the parts are not interchangeable.





The VAR tool set is the original, the one that Park Tool based their original design on. It's simple, durable, and classic. The design allows purchase of an Italian thread set to be used with the English handles, and vice versa.





Hozan Tools makes an excellent tap set, but not facer currently.




All of these tools are excellent quality and have reasonable likelihood of replacement taps and facing cutters being available through the years. Campagnolo, and Park Tool are fairly certain to stand the test of time, and I'd recommend on of those two.
