Product Description
Fix your mouthpiece shank quickly and easily—an essential tool for every band director and repair-minded educator. Simply insert the damaged shank into the correct repair sleeve. Each sleeve is precision-machined to match its corresponding mouthpiece taper, preventing the shank from protruding fully through the sleeve. This ensures a fast, professional repair without stretching, flaring, or deforming the metal.
Insert the stainless-steel repair tool into the shank end and strike it just above the repair sleeve, targeting the dent you want to remove. Repeat as needed for a clean, round, properly trued shank.
TromboneLAB’s Take
Why we like it:
I love how easy this repair kit is to use. It’s simple, smart, and really well designed. More importantly, it gives me everything I need to repair every type of mouthpiece shank damage.
The tapered shank tool has always been great for rounding out shanks from the inside—but it’s also easy to overdo it and accidentally flare the shank. That type of damage used to be a pain to fix… until this kit came along.
The sleeves changed the game. Now I can repair flared shanks quickly and easily or help round them out from the outside with total control.
And honestly, this tool isn’t just for techs. Educators, students, and even pro players can use it confidently. It makes quick, on-the-go repairs possible in minutes.
This kit has become an essential part of my bench because it keeps players playing.
I love it, and I really think you will too!
