Apex Tool Group Llc 21842NN Bastard Mill File 12 Inches

Product Description

The APEX TOOL GROUP LLC 21842NN is a 12-inch single-cut bastard mill file designed for sharpening mill saws and circular saws. Its rectangular profile makes it well suited for draw filing and finishing metal surfaces with consistent, controlled strokes. Two square edges allow the user to cut grooves that match the file width exactly, and the body tapers slightly in width toward the point to improve access in narrow slots and confined areas. This type of file is a standard hand tool in metal fabrication, saw sharpening, and general bench work.

This bastard mill file is used across a range of trade and shop applications including saw sharpening, deburring, and finish filing on flat metal stock. The single-cut tooth pattern produces a smoother finish than a double-cut file and is preferred when draw filing or when fine surface control is needed. It is suitable for use on ferrous metals, tool steel edges, and circular saw teeth in field and shop settings.

Installation Notes

Mill files are hand tools installed by machinists, maintenance technicians, and trade professionals in bench work applications. Secure the workpiece firmly in a vise before filing to maintain control and prevent injury. Use a file card or brush to clear chips from the teeth regularly to prevent pinning and surface scratching. Inspect the tang and handle fit before use to ensure the handle is fully seated and secure.
