Nicholson T37982 Swiss-pattern Equalling File 6.25 in Cut 2

Product Description

The NICHOLSON T37982 is a Swiss-pattern equalling file designed for precision filing and finishing work on metal surfaces. With a 6.25-inch overall length and a 3-inch length of cut, this file delivers controlled material removal in tight tolerances. The rectangular cross-section measures 0.21 inches wide and 0.05 inches thick, making it well suited for fine deburring, fitting, and surface refinement. Finished with a Cut 2 double-cut pattern, it falls into the needle-file precision class and is intended for use by machinists, tool and die makers, and skilled tradespeople who require consistent, repeatable results on close-tolerance work.

This file is appropriate for bench-top metalworking applications including fitting mating surfaces, cleaning up keyways, deburring drilled holes, and finishing slots or recesses where standard files are too coarse or too large. The equalling shape — parallel in width along the length of cut — provides flat contact on both faces, allowing work on parallel surfaces simultaneously. It is commonly used in machine shops, tool rooms, and maintenance environments where precision hand-filing is part of routine workflow.

Key Features

• Cut 2 Swiss-pattern double-cut for smooth, controlled stock removal
• Equalling (rectangular) file shape contacts both parallel surfaces evenly
• Needle-class precision suitable for fine metalwork and close-tolerance fitting
• 3-inch length of cut maximizes usable filing surface on a compact tool
• Tang style allows use with a separate file handle for added control
• 0.05-inch thickness permits access to narrow slots and recesses

Compatibility

Designed as a standard Swiss-pattern equalling file for general precision metalworking applications requiring a Cut 2 needle-class file with a rectangular profile.

Installation Notes

A licensed machinist or skilled tradesperson should select a properly sized handle for the tang before use to ensure safe grip and control. Secure the workpiece in a vise before filing to prevent movement. Inspect the file for cracks or damaged teeth before each use, and never strike a file against a hard surface. Eye protection should be worn during all filing operations per applicable shop safety standards.
