Grobet 31.570 Swiss-pattern Marking Needle File Cut 0

Product Description

The GROBET 31.570 is a Swiss-pattern marking needle file designed for precision material removal in tight tolerances and fine detail work. It features a half-round profile, a Cut 0 tooth pattern for aggressive stock removal relative to needle file standards, and a tang end for use with a separate handle. The overall length is 5.5 inches with a 2.5-inch length of cut, a width of 0.2 inches, and a thickness of 0.06 inches. This file is sized and shaped for machinists, toolmakers, jewelers, and trade professionals who need controlled filing in recesses, slots, and contoured surfaces.

Swiss-pattern needle files like the 31.570 are used in metalworking, toolroom applications, mold and die work, and fine fabrication where standard files are too coarse or too large. The half-round profile provides both a flat and a curved cutting surface, making it suitable for flat faces, inside curves, and shaped cavities. It is commonly used in bench work during fitting, deburring, and surface finishing operations. The tang end requires a separate needle file handle before use.

Installation Notes

A licensed machinist, toolmaker, or experienced trade professional should fit the tang into a properly sized needle file handle before use to prevent hand injury. Always secure the file in the handle before applying filing pressure. Inspect the file for cracks or chips before each use. Follow applicable shop safety practices and wear appropriate eye protection when filing metal.
