Grobet 31.369 Swiss-pattern File 4in Three Square Cut 2

Product Description

The GROBET 31.369 is a Swiss-pattern three-square file designed for precision material removal and fine finishing work on metal, wood, and composite surfaces. At 4 inches overall length with a 9/32-inch width, this compact file fits tight spaces and intricate workpieces where larger files cannot reach. The double-cut, Cut 2 pattern produces an aggressive yet controlled cutting action suited for deburring, shaping, and refining edges on small components. The tang configuration is designed to accept a standard file handle. This file is a staple tool for machinists, tool-and-die workers, jewelers, and trade professionals who require consistent, repeatable results.

This file is well-suited for close-tolerance work in machine shops, fabrication environments, and bench repair settings. Its triangular cross-section makes it the right choice for filing notches, V-grooves, internal angles, and saw teeth. The 4-inch length is appropriate for small precision parts, instrument components, and fine metalwork where a full-size file would be too coarse or too large to control. It is commonly used by HVAC technicians, pipefitters, and electricians for field deburring of cut edges on conduit, tubing, and fittings.

Compatibility

Designed as a standard Swiss-pattern three-square file compatible with any file handle sized to accept a tang-style file. No specific OEM system compatibility is stated for this part.

Installation Notes

Always seat the tang fully into a properly sized file handle before use to prevent hand injury. Inspect the file for cracks or damaged teeth before each use and replace if the cutting surface is worn smooth. Files should be used with controlled strokes and appropriate pressure - do not apply lateral force that could snap the file body, particularly at this compact length. Keep files dry and separated from other metal tools during storage to preserve tooth sharpness.
