Apex 03367NN Flat File Bastard Cut 4 Inch Steel

Product Description

The APEX 03367NN is a 4-inch flat file designed for material removal and finishing work on metal, wood, and composite surfaces. It features a bastard cut, which sits between coarse and second-cut grades, making it suitable for general stock removal where a medium-aggressive cut is needed. The file body measures 4 inches in length and 0.43 inches in width, with a thickness of 0.078 inches. Constructed from steel, it is built to handle repeated use in demanding trade and shop environments. Installation of handles is not included. This file is sold individually and is hard stamped for cut identification.

This flat file is suited for use by machinists, pipefitters, HVAC technicians, plumbers, and electricians who need to deburr cut pipe or conduit, fit metal parts, or clean up threaded fittings and brackets. Its compact 4-inch length makes it practical for work in tight spaces or for bench use on small workpieces. The double-cut sides allow for faster material removal, while the single-cut edges provide more controlled finishing along narrow surfaces or edges.

• Double cut on sides for faster material removal

Compatibility

Installation Notes

This file is sold without a handle — a properly fitted file handle should be installed before use to prevent injury from the tang. Secure the workpiece in a vise when filing to maintain control and reduce fatigue. Inspect the file for cracks or damage before each use and replace if worn. Clean the file teeth regularly with a file card to maintain cutting efficiency.
