P80 Rocket Roller

The Rocket Roller is a rotating bell mandrel with a specially designed concave taper.  One end of the tool accepts one of two interchangeable heads: one for cornet, trumpet, flugelhorn, another for trombone and baritone. The other end is a rotating tapered mandrel, 1” (25.4mm) to 3/8” (9.5mm), which can roll against the bell ring, inside tapers on trumpet, cornet, trombone bells etc.… The concave taper is the secret to the ease of operation and easy blending with the P80 Rocket Roller.
