Grobet 31.619 Swiss-pattern Needle File Square Cut 0

Product Description

The GROBET 31.619 is a Swiss-pattern needle file with a square cross-section and a Cut 0 coarseness rating. It is designed for precision metalworking, deburring, and fitting operations where controlled material removal in tight areas is required. The file measures 6.25 inches overall length with a 3-inch length of cut, making it well suited for detailed hand-filing work on ferrous and non-ferrous metals. The tang-style shank is intended for use with a separate handle. Machinists, toolmakers, jewelers, and skilled trade professionals are the primary users of this type of file.

Swiss-pattern needle files at Cut 0 offer a medium-coarse cut, appropriate for initial shaping and stock removal in precision fitting applications. This file is suited for use on metal components, keyways, slots, and other features where a square profile is needed to reach corners and flat surfaces. It is commonly found in machine shops, maintenance environments, and tool rooms handling close-tolerance work.
