Grobet 31.591 Swiss Pattern File Round Cut 0

Product Description

The GROBET 31.591 is a round Swiss pattern needle file designed for precision material removal in metalworking, toolmaking, and fabrication applications. With an overall length of 6.25 inches and a length of cut of 3 inches, this file features a Cut 0 coarseness rating, which delivers aggressive stock removal while still producing a relatively smooth working surface. The tang-style handle end accepts a separate file handle for a secure grip during use. It measures 0.14 inches in diameter at the cutting section.

This file is suited for use by machinists, toolmakers, jewelers, die makers, and skilled tradespeople who require close-tolerance filing in confined areas or on curved internal surfaces. The needle file format and round cross-section make it well-suited for enlarging round holes, cleaning up circular grooves, and refining curved profiles in metal, hard plastics, and similar materials. It is packaged individually and sold as a single unit.

Installation Notes

A licensed machinist or skilled tradesperson should fit a handle to the tang before extended use to reduce hand fatigue and improve control. File handles should be seated firmly before applying lateral pressure. File only on the forward stroke and lift on the return to extend tooth life. Keep the file clean with a file card to prevent pinning and maintain cutting efficiency.
