Nicholson 37256 Swiss-pattern Equalling Needle File

Product Description

The NICHOLSON 37256 is a Swiss-pattern equalling needle file designed for precision metal finishing, deburring, and fitting work in tight tolerances. It features a rectangular cross-section with a Cut 2 tooth pattern, which provides a fine, smooth cutting action suited for detailed work on ferrous and non-ferrous metals. The file measures 4 inches overall length with a 2-inch length of cut, 0.12 inches wide, and 0.04 inches thick. A tang end is included for use with a separately sourced handle. This tool is used by machinists, tool-and-die workers, pipefitters, and precision trade technicians who require controlled material removal on close-tolerance components.

The NICHOLSON 37256 is well-suited for precision fitting applications in industrial maintenance, HVAC equipment fabrication, plumbing valve seat work, and electrical panel finishing. The needle-level precision classification makes it appropriate for accessing restricted areas and refining small mating surfaces. The rectangular equalling profile allows filing on both flat and edge surfaces without undercutting adjacent faces, which is critical when matching parts to spec in the field or at a bench.

Key Features

• Swiss-pattern Cut 2 tooth configuration for fine, controlled material removal
• Equalling rectangular profile files flat surfaces and edges simultaneously
• Needle-class precision suited for tight-access and close-tolerance work
• 4-inch OAL with 2-inch length of cut for compact reach
• Tang end compatible with standard needle file handles
• Compact 0.12-inch width and 0.04-inch thickness for restricted-access areas

Compatibility

Designed as a general-purpose Swiss-pattern needle file suitable for use on metal components across HVAC, plumbing, electrical, and mechanical trade applications where fine filing and deburring are required.

Installation Notes

A licensed machinist, pipefitter, or qualified tradesperson should select the appropriate handle before use, as the tang end is not intended for bare-hand operation at extended use. Secure the workpiece in a vise or fixture before filing to maintain consistent stroke direction and avoid injury. Inspect the file teeth before use and replace if teeth are worn, loaded, or broken, as a degraded file can slip and damage finished surfaces.
