P88 Tubing True Tool Brasswind Tools

These "Tubing True Tool" mandrels allow the most precision and accurate way to round and straighten brass band instrument tubing, including trombone slide rail tubes. These new precision ground mandrels allow about a 3 times more precise fit than even our regular mandrels; both foreign and domestic. The new 11" length brings this proven idea into the 21st century, so that in conjunction with your N87A trombone pliers you will have the perfect meld of both accuracy and speed. 34 sizes available. The N87A requires approximately 5.5" of work space for best results. The NEW P88 provides 11" for a 100% safety factor. The P88 also has incorporated a delrin "Safety Stop" to help prevent "over run", which is used on our P53 with great success for several years.
