High-quality steel files from FRIEDR. DICK GMBH, specifically designed to create perfectly square screw slots.
Includes #7, #9, and #11 files to cover the most common slot sizes, with a smooth side to cut only on the edge without widening or damaging the slot.
Set contains three files with an overall length of 5¾" (14.6cm) and varying thicknesses for precise cutting, but they are not guaranteed against bending or breakage.
