Grobet 31.530 Swiss Pattern Half Round File Cut 6

Product Description

The GROBET 31.530 is a Swiss-pattern needle file in a half-round profile, designed for precision filing and finishing work on tight tolerances and intricate surfaces. At 6.25 inches overall length with a 3-inch length of cut, this file suits detailed deburring, fitting, and shaping tasks where control matters more than material removal rate. Cut 6 is an extra-fine tooth grade, making it the right choice for final finishing passes on hardened steel, non-ferrous metals, and other close-tolerance workpieces. The tang-style end accepts a standard file handle. Trade machinists, toolmakers, jewelers, and precision mechanics reach for this profile when working in confined areas that a full-size file cannot access.

This file is built for precision hand-filing applications in tool and die work, instrument repair, jewelry fabrication, mold and pattern making, and general metalworking where surface finish is critical. The half-round profile provides two working surfaces: a flat face for flat and convex contours and a curved face for concave radii and curved recesses. At 0.22 inches wide and 0.08 inches thick, the file is narrow enough to work inside slots, notches, and small openings. It is sized for bench use without a handle but accepts a standard tang-style handle sold separately.

Key Features

• Cut 6 extra-fine Swiss-pattern tooth grade for precision finishing passes
• Half-round profile with flat and curved working faces for versatile filing geometry
• 3-inch length of cut concentrates the working surface on the usable stroke
• Needle file size at 6.25 inches OAL fits tight spaces and intricate workpieces
• Tang end compatible with standard aftermarket file handles
• Narrow 0.22-inch width allows access to slots, grooves, and confined recesses

Compatibility

Designed as a standard Swiss-pattern needle file for use with any tang-style file handle and suitable for general precision metalworking, toolmaking, and finishing applications where a half-round Cut 6 profile is specified.

Installation Notes

Files are hand tools requiring no power source, but proper handle attachment is strongly recommended before use to prevent tang injury. Always secure the workpiece in a vise or fixture before filing. File in one direction along the stroke to preserve tooth sharpness and avoid rocking the file across the workpiece surface. Keep the file free of metal filings by brushing with a file card regularly to maintain cutting performance.
