Nicholson T37975 Swiss-pattern Equalling File 6.25 in Cut 0

Product Description

The NICHOLSON T37975 is a Swiss-pattern equalling file designed for precision material removal and surface finishing in metalworking applications. With an overall length of 6.25 inches, a 3-inch length of cut, a width of 0.21 inches, and a thickness of 0.05 inches, this needle-precision file delivers controlled stock removal on tight tolerances. The rectangular cross-section and Cut 0 coarseness make it suited for fine finishing work on flat and parallel surfaces. It features a tang-style end for use with a separately sourced handle. Machinists, tool-and-die workers, and maintenance technicians are the primary users of this file type.

This file is used in bench work, die making, mold finishing, and precision part fitting where surface flatness and edge accuracy are critical. The equalling file shape maintains parallel sides and uniform thickness along the cut length, making it appropriate for opening slots, filing keyways, and truing flat mating surfaces. Its compact 6.25-inch overall length suits close-quarters work or detail filing where a larger file would be impractical. Suitable for use on ferrous metals, non-ferrous metals, and some plastics depending on application requirements.

Key Features

• Cut 0 coarseness for fine finishing and precision surface work
• Rectangular equalling profile maintains parallel sides and uniform thickness
• Needle-precision classification for tight-tolerance metalworking
• 3-inch length of cut provides usable filing surface in a compact form factor
• Tang end compatible with standard aftermarket file handles
• Swiss-pattern tooth geometry for smooth, controlled material removal

Compatibility

Designed as an OEM-style replacement or direct-use Swiss-pattern equalling file compatible with standard tang-style file handles for needle-precision bench and die work applications.

Installation Notes

Always fit a properly sized handle onto the tang before use to prevent hand injury from the exposed tang end. Secure the workpiece in a vise before filing to maintain control and accuracy. Files are single-direction cutting tools — apply pressure on the forward stroke only and lift on the return to preserve tooth life. Do not use this file on hardened steel surfaces harder than the file itself, as this will damage the teeth.
