Grobet 31.571 Swiss-pattern Needle File Half Round Cut 2

Product Description

The GROBET 31.571 is a Swiss-pattern needle file in a half-round shape, designed for precision filing and marking work in tight tolerances and fine detail applications. It features a Cut 2 tooth pattern, which provides a smooth, controlled cut suitable for finishing and deburring operations. The file measures 5.5 inches overall length with a 2.5-inch length of cut, a width of 0.2 inches, and a thickness of 0.06 inches. It ships without a handle, with a tang end for use with a separately sourced handle. Machinists, toolmakers, jewelers, and trade professionals working with fine metal components will find this file suited for precision fit and finish tasks.

This needle file is appropriate for close-tolerance metalwork in tool and die, jewelry fabrication, mold making, and precision mechanical assembly. The half-round profile allows it to work both flat and curved surfaces in a single tool. At 5.5 inches OAL with a short cutting section, it is sized for detailed hand work rather than aggressive stock removal. It is suited for use on ferrous and non-ferrous metals where fine surface finishing is required.

Installation Notes

This file is a hand tool intended for use by machinists, toolmakers, jewelers, and skilled trade professionals. Attach a handle to the tang before use to prevent hand injury from the exposed tang end. Use light, consistent pressure strokes to maintain control and avoid dulling the cut teeth prematurely. Do not use on hardened steel surfaces harder than the file itself, as this can damage the cut pattern.
