Nicholson 12199 Round File 12 Inches Single Cut Smooth

Product Description

The NICHOLSON 12199 is a 12-inch round American-pattern file with a single-cut, smooth configuration. It is used for fine material removal and finishing work on metal, wood, and plastic surfaces. The round profile allows access to curved or circular openings, slots, and contoured surfaces that flat files cannot reach. At 0.5 inches in diameter and 12 inches in overall length, it provides good reach and control for detailed hand filing. The tang end accepts a standard file handle, giving the user a secure grip during use. This tool is suited for machinists, pipefitters, fabricators, and general trade technicians who require smooth, controlled stock removal.

This file is appropriate for light deburring, smoothing, and shaping tasks in maintenance, fabrication, and repair settings. The single-cut tooth pattern removes material in one direction and produces a finer, smoother finish than double-cut files. It is commonly used in HVAC, plumbing, electrical, and general industrial trades for cleaning pipe ends, enlarging holes, and fitting parts to close tolerances. Its non-flexible body maintains consistent contact across the work surface.

Installation Notes

Always fit the file onto a properly sized handle before use to prevent tang injury. Secure the workpiece in a vise or clamp before filing to maintain control and accuracy. Apply consistent forward pressure on the cutting stroke and lift or ease pressure on the return stroke to preserve tooth life. Inspect the file for cracks or missing teeth before use and replace if damaged.
