E41 Flat Spring Hole Punch
An ideal way to punch holes in flat springs. Used primarily for punching an extra hole in flat springs where there are two screws, as in bassoons and some flutes. The hardened punch and die will punch a .060” (1.5mm) hole in a flat spring. New hole will accept a 0 X 80 flat spring screw. There is a T-handle on the screw punch for easy operation. One of our most popular specialized woodwind bench tools.
