Our lighted tone hole gauge is the ultimate way to locate flute tone hole imperfections.  Before setting flute pads make sure that the tone hole is flat enough for a pad to seal with first touch.  The tool is made of a comfortable and beautiful wooden handle, a precision ground and hardened gauge and a light with replaceable battery that shines into the tone hole illuminating gaps between the hole and the gauge.

Very fine grit level stone to assist in leveling flute tone holes. Can level the tone hole face and remove minor nicks and dings in the tone hole face. Use in conjunction with the flute tone hole facer/tester or lighted tone hole flatness gauge.
