Grobet 31.348 Swiss-pattern File 4 in Square Cut 2

Product Description

The GROBET 31.348 is a Swiss-pattern file designed for precision metal filing, deburring, and finishing work in tool-and-die, machinist, and general metalworking applications. Cut 2 refers to a medium-fine tooth grade that removes material efficiently while leaving a relatively smooth surface. The square profile measures 5/32 inches wide with a 4-inch overall length and is finished with a tang for use with a standard file handle. This file is suited for work in slots, keyways, square holes, and tight internal corners where a flat or round file cannot reach.

Swiss-pattern files at this length and cut grade are commonly used in bench work environments including machine shops, tool rooms, jewelers benches, and precision fabrication settings. The 4-inch overall length makes this a short file appropriate for detail work and confined spaces. The double-cut tooth pattern on both faces and edges allows the technician to work efficiently on ferrous and non-ferrous metals. A file handle should be installed on the tang before use to prevent hand injury during operation.

Installation Notes

A licensed machinist, toolmaker, or skilled tradesperson typically uses this file as a hand tool requiring no power source. Always seat a properly sized file handle firmly onto the tang before use to prevent the tang from contacting the palm during operation. Inspect the file for cracks or missing teeth before each use and replace if damaged. Store files individually or in a rack to prevent tooth-to-tooth contact that causes premature wear.
