Grobet 31.463 Swiss-pattern Barrette Needle File Cut 4

Product Description

The GROBET 31.463 is a Swiss-pattern barrette needle file designed for precision filing and deburring in tight or hard-to-reach areas. With a cut 4 (smooth) tooth pattern, it removes material with fine control, making it well-suited for finishing work, fitting, and detail shaping on metal parts. The barrette profile is flat on one face and safe (uncut) on the opposite face, allowing work right up to a shoulder or edge without marring adjacent surfaces. The tang end accepts a separate handle, sold independently. Overall length is 6.25 inches with a 3-inch length of cut.

This file is used in tool-and-die, watchmaking, jewelry fabrication, precision machining, and general metalworking trades. The needle file size and cut 4 finish make it a go-to for final fitting of mating parts, cleaning up keyways, and sharpening or dressing tooling. It performs well on steel, aluminum, brass, and similar metals. Installers and machinists working with small components, instrument assemblies, or fine mechanical parts will find the profile and cut appropriate for controlled stock removal without surface damage.

Key Features

• Barrette profile with a safe (uncut) face prevents accidental damage to adjacent surfaces
• Cut 4 tooth pattern delivers fine, smooth material removal for precision finishing
• Swiss-pattern construction provides consistent tooth geometry across the full length of cut
• Tang end accepts a standard needle file handle for secure grip during use
• Compact needle file size suits detailed work in confined spaces

Compatibility

Designed as an OEM-style Swiss-pattern needle file compatible with standard needle file handles sold separately; suitable for use on ferrous and non-ferrous metals in precision hand-filing applications.

Installation Notes

This file is a hand tool requiring no power source or trade licensing for general use. Attach a suitable needle file handle to the tang before use to maintain control and prevent injury. File in one direction with consistent pressure; avoid rocking the file, which can round edges or reduce cut accuracy. Inspect the file for cracks or broken teeth before each use and replace if damaged.
