Nicholson 21701HNN Mill File 10 Inches Single Cut Bastard

Product Description

The NICHOLSON 21701HNN is a 10-inch American-pattern mill file designed for shaping, smoothing, and deburring metal workpieces. It features a single-cut tooth pattern in a bastard cut coarseness, which removes material efficiently while producing a relatively smooth surface finish. The file measures 31/32 inches wide and 11/64 inches thick, giving it the flat, tapered profile characteristic of the mill file style. An ergonomic handle is included, providing a secure grip during use. This file is a standard hand tool used by machinists, maintenance technicians, HVAC fabricators, and pipefitters for general metalwork tasks on ferrous and non-ferrous materials.

This file is suited for bench and field use wherever controlled metal removal is required. Common applications include smoothing burrs from cut pipe or conduit, dressing machined edges, fitting metal parts, and sharpening certain cutting tools. The non-flexible body keeps the cutting surface stable under pressure. The 10-inch overall length makes it manageable for both open bench work and tighter fitting tasks encountered in mechanical and trade installations.

Key Features

• Rated for metal material applications including ferrous stock common in HVAC, plumbing, and electrical trades

Compatibility

Designed as a general-purpose American-pattern mill file suitable for hand filing tasks on metal materials in trade and maintenance applications.

Installation Notes

This is a hand tool requiring no power source or special installation. Secure the workpiece in a vise before filing to prevent movement and maintain control. Always file with forward strokes and lift the file on the return stroke to preserve tooth sharpness. Wear appropriate eye protection and gloves when filing metal to guard against chips and sharp edges.
