Grobet 31.148 Swiss-pattern Hand File 6in Cut 4

Product Description

The GROBET 31.148 is a Swiss-pattern hand file designed for precision material removal and finishing work on metal, plastic, and similar workpiece materials. At 6 inches overall length with a rectangular profile, it measures 3/4 inches wide and 5/32 inches thick. The double-cut, Cut 4 tooth pattern produces a fine, smooth surface finish suited to detail work and close-tolerance fitting. A tang end accommodates a standard file handle. This file is sized for bench work and hand-tool operations performed by machinists, tool-and-die workers, jewelers, and precision trade technicians who require consistent stock removal at a controlled grade.

This file fits residential and commercial shop environments where fine hand-filing is required. Common applications include deburring machined parts, fitting keyways, cleaning up weld seams, and finishing soft metals or hardened tool steel. The 6-inch length and rectangular cross-section make it well-suited to flat surfaces, slots, and shoulders. Cut 4 in the Swiss-pattern grading system falls in the fine range, making this tool appropriate for finishing passes rather than aggressive stock removal. It is a single-piece, tang-style file intended for use with a separately sourced handle.

Key Features

• Swiss-pattern Cut 4 double-cut tooth profile for fine, controlled material removal
• Rectangular cross-section at 3/4 inches wide and 5/32 inches thick fits flat surfaces and slots

Compatibility

Designed as a standard Swiss-pattern hand file compatible with any conventional file handle sized for a tang-style file; no proprietary mounting or adapter required.

Installation Notes

Always fit a proper handle to the tang before use to prevent hand injury from an exposed point. Secure the workpiece in a vise or fixture before filing to maintain control and accuracy. Files should be used with controlled, forward-stroke pressure only; dragging the file backward on the return stroke dulls teeth prematurely. Store files separated from one another and from other metal tools to protect tooth edges.
