Nicholson 21694HNN Mill File 8 Inch Bastard Cut

Product Description

The NICHOLSON 21694HNN is an 8-inch American-pattern mill file designed for sharpening, smoothing, and deburring metal workpieces. It features a single-cut, bastard-cut tooth pattern, which removes material at a moderate rate while leaving a relatively smooth finish. At 25/32 inches wide and 9/64 inches thick, this file is sized for general-purpose hand filing tasks. An ergonomic handle is included, giving the user a secure grip during extended use. The file is non-flexible and suited to working on flat and slightly curved metal surfaces. It is a standard tool for machinists, maintenance technicians, and fabricators who need reliable material removal on metal stock.

This mill file is used across a broad range of trade and shop applications including sharpening saw blades and lawn mower blades, smoothing weld seams, dressing metal edges, and fitting parts during assembly or repair. The bastard cut makes it versatile for both roughing and intermediate finishing passes on ferrous and non-ferrous metals. It is equally at home in an HVAC sheet metal shop, a plumbing or mechanical room, or a general maintenance toolbox. The included ergonomic handle is ready to use out of the package without any additional fitting.

Installation Notes

Files should always be used with the handle properly seated to prevent tang injuries during use. Apply forward stroke pressure and lift on the return stroke to preserve tooth sharpness. Secure the workpiece in a vise before filing to maintain control and accuracy. Never use a file as a pry bar or striking tool, as the hardened steel is brittle and can fracture.
