Nicholson 39992N Swiss Pattern File 12 in Regular Pillar

Product Description

The NICHOLSON 39992N is a Swiss-pattern pillar file designed for precision filing and finishing work on metal surfaces. It measures 12 inches in overall length, 0.76 inches wide, and 0.25 inches thick, with a rectangular cross-section and a tang end for use with a separate file handle. The double-cut, Cut 0 tooth pattern delivers smooth, controlled stock removal suited to fine fitting, deburring, and finishing tasks. This file is a standard-precision tool used by machinists, pipefitters, tool-and-die workers, and maintenance trades requiring accurate hand filing on ferrous and non-ferrous metals.

The 39992N is appropriate for general-purpose metal filing in both shop and field environments. The regular pillar shape, with its parallel sides and rectangular profile, is commonly used for filing slots, keyways, flat surfaces, and right-angle shoulders. Its Cut 0 rating indicates a coarse tooth count within the Swiss-pattern grading system, making it effective for initial material removal while still maintaining the controlled cutting action expected from Swiss-pattern files. Typical applications include maintenance and repair work, toolroom operations, and fabrication tasks where hand filing precision is required.

Installation Notes

This file is a hand tool and does not require installation in the traditional sense. Always fit a properly sized handle to the tang before use to prevent hand injuries during operation. Inspect the file for cracks or missing teeth before each use, and never use a file as a pry bar or striking tool. File storage in a rack or individual sleeve prevents tooth damage and extends service life.
