Grobet 31.388 Swiss-pattern Warding File 3in Cut 2

Product Description

The GROBET 31.388 is a Swiss-pattern warding file designed for precise filing work in tight or narrow keyway slots, notches, and intricate metal surfaces. This file measures 3 inches in overall length and features a Cut 2 double-cut tooth pattern, which removes material efficiently while still producing a reasonably smooth finish. At 23/64 inches wide and 1/32 inches thick, the thin rectangular profile is purpose-built for accessing confined areas that standard files cannot reach. It is fitted with a tang for use with a compatible file handle. This tool is used by machinists, locksmiths, toolmakers, and maintenance tradespeople who require precision hand filing on ferrous and non-ferrous metals.

The 31.388 is suited for detail work on keyways, lock components, slots, and light deburring in confined spaces. The warding profile and slim cross-section make it a standard choice for locksmith work and fine metalworking applications where rectangular geometry and tight tolerances are required. The double-cut tooth pattern supports controlled stock removal on steel, brass, aluminum, and similar materials in both bench and field settings.

Installation Notes

Always mount the tang securely in a properly sized file handle before use to prevent hand injury. Secure the workpiece in a vise or fixture before filing to maintain control and accuracy. Files should not be used on rotating machinery or as pry tools. Inspect the file for cracks or damage before each use and replace if the teeth are worn or the body is compromised.
