The sax bell tools are designed to reach dents and dings in the very outer edge and flare of the sax bell- allowing burnishing or rolling right up to the rolled edge- a spot that's really difficult to get with other conventional dent tools.
Made for alto and tenor saxophone bells- each tool has two profiles- a modern bell flare and a longer curve 'vintage' bell flair. The mandrel is threaded onto any dent rod with 3/8-16 threading. The mandrel threads into the side of the tool so you can work in front of or behind the the mandrel without the rod getting in the way. Also works for some sizes of small brass like trumpet and cornet bell flares.
Stainless steel construction.
