Grobet 31.298 Swiss-pattern Round File 8in Cut 4

Product Description

The GROBET 31.298 is a Swiss-pattern round file designed for precision filing and finishing work across metal, wood, and composite materials. At 8 inches overall length with a 5/16-inch diameter, it delivers a Cut 4 finish - a fine-grade double-cut suited for detailed deburring, smoothing, and fitting work in tight or contoured areas. The tang end accepts a standard file handle for secure grip during use. This tool is built for trade professionals who require consistent, repeatable results in close-tolerance applications.

This file is used in HVAC, plumbing, electrical, and general mechanical trades wherever precision material removal is needed. Typical applications include deburring pipe ends, fitting conduit knockouts, smoothing burrs on sheet metal edges, and refining slots or holes in fabrication work. The round profile makes it especially effective for enlarging circular openings and working curved internal surfaces. Its compact diameter suits work in confined spaces where larger files cannot reach.

Key Features

• Cut 4 double-cut pattern delivers fine, controlled material removal for precision finishing
• Round file shape works curved surfaces, slots, and circular openings
• 8-inch overall length provides reach and leverage for bench and field work
• 5/16-inch diameter fits narrow grooves and small-diameter holes
• Tang end compatible with standard replacement file handles
• Swiss-pattern construction for consistent cut geometry across the full file length

Compatibility

Designed as a standard Swiss-pattern round file for use with any compatible tang-style file handle sold separately. Suitable for use on ferrous and non-ferrous metals, plastics, and similar materials in trade and fabrication applications.

Installation Notes

Always fit the tang securely into an appropriately sized file handle before use to prevent hand injury. Apply consistent forward pressure only - filing on the return stroke dulls the cut teeth prematurely. Wear appropriate eye protection when deburring or filing metal. Keep the file clean of metal filings using a file card or brush to maintain cutting efficiency.
