Grobet 31.503 Swiss-pattern Equalling Needle File Cut 4

Product Description

The GROBET 31.503 is a Swiss-pattern equalling needle file with a Cut 4 finish, designed for precision metalworking and detail filing applications. With an overall length of 5.5 inches and a 2.5-inch length of cut, this file is built for fine, controlled material removal on flat and parallel surfaces. The rectangular profile and needle-file classification make it a standard choice for jewelers, toolmakers, machinists, and die-repair technicians who need consistent, accurate results on close-tolerance work. It features a tang end, intended for use with a separately sourced handle.

This file is suited for bench work requiring fine finishing on ferrous and non-ferrous metals, plastics, and similar materials. The equalling file shape - rectangular in cross-section with both faces and edges cut - allows work on flat surfaces, slots, and right-angle corners simultaneously. At 5.5 inches OAL, it fits comfortably in hand-held bench applications typical of toolroom, jewelry, and precision-assembly environments. Cut 4 provides a fine tooth pattern appropriate for finishing passes and light stock removal rather than aggressive cutting.

Key Features

• Swiss-pattern construction for consistent tooth geometry and precise material removal
• Cut 4 tooth grade - fine cut suitable for finishing and close-tolerance work
• Equalling (rectangular) file shape cuts on both faces and both edges
• Needle-file classification for detail and precision bench work
• Tang end for use with a compatible file handle
• 2.5-inch length of cut within a 5.5-inch overall length

Compatibility

Designed as a standard Swiss-pattern needle file for use in precision metalworking, toolroom, and jewelry bench applications where a Cut 4 equalling profile is required.

Installation Notes

This file ships as a tang-end tool without a handle; a compatible handle should be seated securely before use to prevent hand injury. Use only with appropriate personal protective equipment including eye protection and cut-resistant gloves when filing. Apply consistent, controlled strokes to preserve tooth life and avoid rocking the file across the workpiece surface.
