Grobet 31.517 Swiss-pattern Half Round File 4in Cut 2

Product Description

The GROBET 31.517 is a Swiss-pattern needle file in a half round profile, designed for precision hand-filing work in tight tolerances and detailed finishing applications. At 4 inches overall length with a 1.75-inch length of cut, this Cut 2 file delivers a smooth second-cut action suited for deburring, light material removal, and surface refinement on metal, plastic, and similar materials. The tang-end design accepts standard file handles sold separately. At 0.05 pounds, it is a lightweight precision tool sized for detail work requiring control over a small contact area.

This file is suited for machinists, toolmakers, jewelers, and trade technicians who need a compact, accurate file for work in recesses, slots, and curved or flat surfaces. The half round cross-section provides two working faces: a flat face for flat and convex surfaces, and a curved face for concave profiles and bore interiors. Typical applications include fitting keyways, cleaning up casting flash, refining threaded holes, and light shaping on ferrous and non-ferrous metals.

Installation Notes

This file is a hand tool and does not require electrical isolation or system shutdown before use. Secure a properly sized handle onto the tang before use to prevent hand injury from the exposed tang end. Apply consistent, even strokes and avoid lateral pressure that can snap the file body on fine needle files. Inspect the file for cracks or chips before use, as damaged files should be removed from service.
