صنبور محور Park Tool (TAP-12.3)

My old frame's derailleur hanger threads were completely gummed up, but this tap cut through the corrosion like butter. It's precise enough that I didn't worry about damaging the aluminum, and the threads came out factory-fresh. Just what I needed for that M12 x 1.75 cleanup job.

My frame's disc mount threads were totally cross-threaded, but this tap cut through the aluminum cleanly and left a perfect M12 x 1.75 thread. The precise cutting flutes made the work feel effortless and saved me from a costly frame replacement.

After chasing a few sketchy frame threads on older builds, this tap cleaned them out perfectly and the M12 x 1.75 pitch cut smooth the whole way. Solid, sharp tool that saves you from a real headache.
