Grobet 31.451 Swiss-pattern Barrette Needle File Cut 2

Product Description

The GROBET 31.451 is a Swiss-pattern barrette needle file designed for precision filing and finishing work on close-tolerance surfaces. At 4 inches overall length with a 1.75-inch length of cut, this file delivers controlled material removal in tight spaces where standard files cannot reach. The Cut 2 designation indicates a second-cut tooth pattern, providing a balance between stock removal and surface finish. The barrette profile is flat on one side and safe (uncut) on the opposite face, allowing work against a shoulder or mating surface without marring adjacent areas. No handle is included; the tang style accepts a standard needle file handle. Machinists, toolmakers, jewelers, and precision trade technicians are the primary users.

This file is suited for deburring, refining keyways, cleaning up slots, and finish-filing flat or angled surfaces on metal workpieces. The needle-file classification means it is intended for fine, detailed work on small parts rather than heavy stock removal. The barrette cross-section is particularly useful when filing into corners or along a single flat face without cutting into an adjacent surface. It fits naturally into tool-and-die, mold-making, and precision fabrication workflows.

Installation Notes

Needle files are hand tools used by machinists, toolmakers, and precision tradespeople; no power or electrical shutoff is required. Secure the workpiece firmly before filing to maintain control and prevent injury. Attach a properly sized handle to the tang before use to reduce the risk of hand puncture. Inspect the file for cracks or tooth damage before each use and replace if compromised.
