Grobet 31.615 Swiss Pattern Needle File Square Cut 0

Product Description

The GROBET 31.615 is a Swiss-pattern needle file with a square profile, designed for precision filing and deburring in tight tolerances. It features a Cut 0 (bastard-equivalent for needle files) tooth pattern, making it suitable for faster material removal on softer metals, plastics, and composites. The file measures 5.5 inches overall length with a 2.5-inch length of cut and a working width of 0.09 inches. A bare tang is provided for use with a separate handle. This tool is used by machinists, tool-and-die workers, jewelers, and trade professionals requiring precise hand-filing work.

Swiss-pattern needle files are standard in precision metalworking, instrument repair, and fine fabrication environments. The square cross-section allows filing of slots, keyways, and square openings where flat files cannot reach. The short length of cut and narrow width make this file well suited for detail work on small components, molds, and tooling. It is appropriate for both shop and field use wherever hand-tool finishing is required.

Key Features

• Square cross-section profile for filing slots, keyways, and square recesses
• Cut 0 tooth pattern for efficient material removal on softer substrates
• 2.5-inch length of cut provides an adequate working surface on small parts
• 0.09-inch working width fits narrow slots and confined areas
• Bare tang style accepts standard needle-file handles sold separately
• Swiss-pattern construction for consistent tooth geometry and cutting performance

Compatibility

Designed as an OEM-style precision needle file for use in general metalworking, tooling, and fabrication applications requiring a square-profile Swiss-pattern file.

Installation Notes

Install a properly sized handle onto the tang before use to prevent injury during filing operations. Always secure the workpiece in a vise or fixture before applying file pressure. File in the forward stroke only and lift on the return to extend tooth life. No power tools, codes, or utility shutoffs apply to hand-file use.
