Apex Tool Group Llc 08243NN Mill Bastard File 4 Inches

Product Description

The APEX TOOL GROUP LLC 08243NN is a 4-inch mill bastard file engineered for precision metalworking and saw maintenance tasks. Built to the American pattern, this file features a rectangular cross-section with single-cut teeth on both sides and edges, plus two square edges for controlled material removal. The slight taper in width along the length gives tradespeople consistent bite and smooth draw-filing action. Electricians, machinists, pipefitters, and general tradespeople reach for this style of file when sharpening mill saws, circular saw blades, or finishing metal edges with a clean, flat surface.

This file is well suited for sharpening mill and circular saw teeth, draw-filing flat stock, and finishing metal surfaces in shop and field environments. Its compact 4-inch length makes it manageable for detail work on saw blades and tight workpieces. The single-cut pattern leaves a smoother finish than a double-cut file, making it a practical choice when surface quality matters alongside material removal rate. Sold in a boxed format, it is commonly stocked by contractors, maintenance crews, and tool rooms that keep multiple sizes on hand.

Key Features

• American pattern, rectangular cross-section for consistent flat filing
• Single-cut teeth on sides and edges for smoother finish cuts
• Two square edges allow filing into corners without relieving adjacent surfaces
• Slight width taper along the length for progressive cutting control
• 4-inch length suited for detail work on saw blades and small workpieces
• Boxed packaging for clean storage and jobsite transport

Compatibility

Designed as a standard American-pattern mill bastard file for use with mill saws, circular saw blades, and general metalworking applications requiring a single-cut flat file.

Installation Notes

This file is a hand tool requiring no power source. Secure the workpiece in a vise before filing to maintain control and prevent injury. Always file with the teeth direction in mind — single-cut files cut on the forward stroke. Wear appropriate hand protection when working near sharp saw teeth or metal edges.
