Grobet 31.505 Swiss-pattern Equalling File Cut 00

Product Description

The GROBET 31.505 is a Swiss-pattern equalling file with a rectangular cross-section, designed for precision material removal and surface finishing in metalworking, tool-and-die, and instrument repair applications. It measures 6.25 inches overall length with a 3-inch length of cut. Cut 00 designates an extra-coarse tooth pattern within the Swiss-pattern grading system, making this file suited for rapid stock removal on softer metals and non-ferrous alloys. The needle-precision designation indicates tight dimensional tolerances along the file body. The tang end is bare, requiring a separate handle before use.

This equalling file is used where parallel flat surfaces must be maintained and both faces need to cut simultaneously. Common applications include fitting keyways, deburring flat stock, opening slots, and truing mating surfaces in precision assemblies. It is a standard tool in tool-and-die shops, watchmaking and instrument repair benches, jewelers workshops, and general metalworking operations. The rectangular profile with uniform thickness along the cut length makes it well suited for work inside confined flat openings.

Key Features

• Swiss-pattern grading for consistent tooth geometry and dimensional accuracy
• Cut 00 extra-coarse tooth pattern for rapid stock removal
• Equalling (rectangular) profile cuts on both flat faces simultaneously
• Needle-precision classification with tight body tolerances
• 3-inch length of cut provides a focused working surface
• Tang end accepts standard file handles sold separately

Compatibility

Designed as an OEM-style Swiss-pattern needle file for use with standard file handles compatible with tang-style files. No specific system or model compatibility is stated for this part.

Installation Notes

A file handle must be seated securely on the tang before use to prevent hand injury from the exposed tang point. Inspect the file for cracks before use and never use a file as a pry bar or striking tool. Files should be used with controlled strokes appropriate to the material being worked, and eye protection is recommended at all times when filing metal. Store separately from other files to prevent tooth damage from contact.
