DIAMOND TONEHOLE FILES FOR FLUTES
Make sure that the toneholes rims are flat before installing these pads. I supply a set of excellent rotary tone hole files/pilots for this purpose.
JS flute tonehole files come supplied with your choice of #300, 600 or 1200 grit diamond abrasive which cuts fast and smooth. These high quality finishing discs are made of precision surface ground steel with diamonds embeded directly into the metal. These are the only files that give you a perfectly flat tonehole quickly and easily every time. Other files are a slow struggle in comparison. For a fine finish I recommend the standard 600 and then the 1200 grit finishing discs. The 300 grit discs are better for student quality flutes or general roughing in. Do not use on nickel plated flutes or they will clog up. The back side of each steel disc doubles as a surface guage to check for perfect flatness of the tonehole. Basic size pilots are supplied with the files. Inbetween size pilots in .5mm increments are also available (see below).
