Grobet 31.372 Swiss-pattern File 6 in Three Square Cut 0

Product Description

The GROBET 31.372 is a Swiss-pattern three square file designed for precision hand filing in metalworking, toolmaking, and finishing applications. The triangular cross-section with double-cut teeth on all three faces removes material efficiently while allowing controlled shaping of internal angles, grooves, and tight corners. At 6 inches in overall length and 3/8 inches wide, this Cut 0 file delivers a coarse tooth pattern suited for initial stock removal on hard metals. It is supplied with a tang for use with a separately sourced handle and is sold individually.

Swiss-pattern files are standard tools in toolrooms, die shops, and precision fabrication environments where consistent tooth geometry and tight tolerances matter. The three square profile is particularly useful for filing interior angles of approximately 60 degrees, clearing burrs from threaded fasteners, and shaping keyways or slots. This file is appropriate for machinists, tool and die makers, jewelers, and skilled tradespeople who require repeatable results on ferrous and non-ferrous metals.

Installation Notes

This file is a hand tool and requires no power or electrical shutoff prior to use. Always seat the tang fully into a properly sized file handle before applying pressure to reduce the risk of hand injury. Wear appropriate cut-resistant gloves and eye protection during filing operations. Inspect the file for cracks or damage before each use, and never use a file as a pry bar or striking tool.
