Nicholson 08306NN Mill File 4 Inches Single Cut Smooth

Product Description

The NICHOLSON 08306NN is a 4-inch American-pattern mill file designed for smooth, controlled material removal on metal surfaces. It features a single-cut tooth pattern, which produces a finer finish than double-cut files and allows the user to apply more controlled pressure during filing. The file measures 7/16 inches wide and 5/64 inches thick, with a tang end for use with a standard file handle. At 0.06 pounds, it is a compact, lightweight hand tool suited for precision deburring, edge dressing, and fine sharpening tasks.

This mill file is used in metalworking, maintenance, and fabrication settings where a smooth cut is required. Its compact 4-inch length makes it well suited for detail work, tight spaces, and fine finishing passes on smaller workpieces. It is a standard tool for machinists, pipefitters, millwrights, HVAC technicians, and general trade professionals who need a reliable hand file for light metal conditioning. Material application is metal, making it appropriate for ferrous and non-ferrous stock.

Installation Notes

A licensed or journeyman-level trade professional or experienced machinist typically selects and uses hand files as part of routine maintenance or fabrication work. Always secure the workpiece in a vise before filing to prevent movement and injury. Attach an appropriate handle to the tang before use — operating a tang file without a handle risks hand injury. Inspect the file for cracks or missing teeth before each use and replace if damaged.
