Nicholson 37619 Swiss-pattern Equalling Needle File

Product Description

The NICHOLSON 37619 is a Swiss-pattern equalling needle file designed for precision metalworking, toolmaking, and fine finishing tasks. With a rectangular cross-section and Cut 2 tooth pattern, it removes material smoothly while leaving a refined surface finish. The file measures 5.5 inches overall length with a 2.5-inch length of cut, making it well-suited for detailed work in confined areas. It features a tang end for use with a compatible file handle. At 0.19 inches wide and 0.04 inches thick, this is a slender, needle-style file built for accuracy. Machinists, toolmakers, and skilled tradespeople typically reach for this file when working on dies, molds, or tight-tolerance components.

This file is suited for precision hand-filing applications where control and surface quality matter. Its equalling (rectangular) shape allows flat surface work and right-angle corner finishing. The Cut 2 designation indicates a second-cut tooth pattern, which balances material removal rate with surface refinement — appropriate for general precision filing after rough stock removal. It is commonly used in machine shops, maintenance and repair operations, and fabrication environments where needle files are standard hand tools.

Compatibility

Designed as a standard Swiss-pattern needle file for use in precision metalworking, toolmaking, die and mold finishing, and general maintenance applications requiring a rectangular file profile.

Installation Notes

This file is a hand tool requiring no power source or installation. Always attach a proper handle to the tang before use to prevent hand injury from the exposed tang point. Use appropriate personal protective equipment including safety glasses when filing metal. Store files individually or in a rack to protect cutting teeth and prevent contact with other metal tools that can dull the file surface.
