Mouthpiece Thinning Tool Knurled Mouthpiece Flattening Tool Metal Machined Finish

This compact music repair tool features a rigid metal body with two opposing rectangular clamping blocks and a small, solid build for controlled bench work. Designed as a mouthpiece tool, it helps thin and flatten the mouthpiece interface for repair and shaping tasks on brass instrument parts. The coil-powered-loaded center section supports steady pressure during use, helping keep the workpiece seated while adjustments are made. Knurled tightening parts give the brass mouthpiece repair tool a more secure grip and easier manual control during setup and operation. As a mouthpiece flattening tool and mouthpiece thinning tool, it is intended to refine the interface shape for careful restoration work.
