Grobet 31.307 Swiss-pattern Round Parallel File 4in Cut 0

Product Description

The GROBET 31.307 is a Swiss-pattern round parallel file designed for precision metal finishing and deburring work. At 4 inches overall length with a 1/8-inch diameter round profile, this compact file delivers controlled material removal in tight bores, slots, and curved surfaces. Cut 0 grade indicates a coarse tooth pattern suited for aggressive stock removal on softer metals and initial shaping passes. The double-cut tooth geometry produces fast cutting action with consistent surface contact. A tang is included for use with a standard file handle. Machinists, toolmakers, and metalworking tradespeople are the primary users of this tool.

This file is suited for bench work, die finishing, mold work, and general metal fitting tasks in shop or field environments. The 4-inch length and 1/8-inch round parallel body make it a practical choice for accessing confined areas where larger files cannot reach. It is commonly used on aluminum, brass, mild steel, and similar workpiece materials during fitting, deburring, and surface preparation operations.

Installation Notes

Always secure a properly sized handle onto the tang before use to prevent hand injury from the exposed tang end. Inspect the file for cracks or missing teeth before each use and replace if damaged. Files are cutting tools, not pry bars or levers - do not apply lateral bending force. Keep the file clean with a file card or brush to maintain cutting efficiency and extend service life.
