Grobet 31.613 Swiss-pattern Needle File 4 in Square Cut 2

Product Description

The GROBET 31.613 is a Swiss-pattern needle file with a square profile and a Cut 2 (smooth) tooth grade. At 4 inches overall length with a 1.75-inch length of cut, this file is built for precision detail work in confined areas and fine finishing tasks. The tang style requires a separate handle, giving technicians and tradespeople direct control during use. With an overall width of 0.06 inches, it is suited to tight slots, keyways, and intricate surfaces where a standard-size file cannot reach.

This needle file is used in applications requiring close-tolerance material removal and surface refinement. Typical use cases include deburring metal parts, fitting keys and slots, cleaning up welds in tight spaces, and finishing work on ferrous and non-ferrous metals. It is a standard tool for machinists, electricians, HVAC technicians, and plumbers who need to dress fittings, brackets, or machined components during installation or repair. The compact 4-inch length makes it practical for fieldwork and bench use alike.

Installation Notes

A separate handle should be fitted to the tang before use to prevent injury and maintain control. Always wear eye protection when filing metal to guard against debris. File in a controlled stroke appropriate to the material and desired finish. Keep the file clean of metal filings using a file card or brush to maintain cutting efficiency.
