The GROBET 31.524 is a Swiss-pattern half round needle file designed for precision filing, deburring, and surface finishing in tight tolerances. With a cut 0 coarseness rating, it removes material efficiently while still producing a relatively smooth finish suitable for metalworking, toolmaking, and fine fabrication work. The file measures 6.25 inches overall length with a 3-inch length of cut, a width of 0.22 inches, and a thickness of 0.08 inches. It features a tang end for use with a separately sourced handle. Machinists, toolmakers, jewelers, and skilled trade professionals typically reach for this file when working in contoured or curved profiles that demand both flat and radiused filing surfaces in one tool.
This file is suited for applications requiring controlled stock removal on curved, flat, or angled surfaces such as die work, mold fitting, keyway cleaning, and general bench filing. The half round profile makes it especially useful where inside radii or curved recesses need to be dressed without marring adjacent flat surfaces. Cut 0 coarseness is a standard starting point for initial shaping before stepping down to finer cuts. It is commonly used in machine shops, maintenance and repair operations, and precision fabrication environments where hand-filing accuracy matters.
Designed as an OEM-style replacement or direct addition to standard Swiss-pattern needle file sets used in bench filing, toolmaking, and precision metalworking applications.
A licensed or experienced tradesperson should fit a proper handle onto the tang before use to prevent hand injury during filing strokes. Secure the workpiece in a vise or fixture to maintain control and accuracy. Do not use the file as a pry tool or strike it with a hammer, as the hardened steel body is brittle and can fracture. Keep the file clean of metal filings using a file card or brush to maintain cutting efficiency.
