Nicholson 02147N Round Double Cut File 8 Inches

Product Description

The NICHOLSON 02147N is an 8-inch round double cut file designed for precision filing on metal surfaces, including chainsaw chain sharpening. Manufactured in the American pattern, this file features a smooth cut double tooth configuration that removes material efficiently while leaving a refined surface finish. The round profile measures 1/4 inch in diameter, making it well suited for working in curved gullets and tight profiles. A tang end is included for use with a standard file handle. At 0.1 pounds, the tool is lightweight and easy to control during extended use.

This file is a standard tool for chainsaw maintenance, used by arborists, logging professionals, outdoor power equipment technicians, and experienced DIYers to restore sharpness to chain cutter teeth. The 8-inch length and 1/4-inch round cross-section match common chain pitch requirements found in residential and commercial chainsaw applications. It is also applicable to general metalworking tasks where a round smooth-cut file profile is required, such as deburring, enlarging holes, and finishing curved internal surfaces.

Installation Notes

Always secure the workpiece in a vise or use a proper chain filing guide before beginning work. Disengage and de-energize the chainsaw or power tool before filing any cutting component. A file handle should be fitted to the tang before use to prevent hand injury. Apply consistent, forward-stroke pressure and lift the file on the return stroke to preserve tooth edge life.
