Value Collection -20567-8 Three Square File 8 in Bastard Cut

Product Description

The VALUE COLLECTION -20567-8 is an 8-inch American-pattern three square file designed for precision material removal on ferrous and non-ferrous workpieces. The three square (triangular) cross-section makes it well suited for filing interior angles, clearing tap flutes, and dressing milling cutters. This file features a bastard cut for moderate stock removal and a double cut pattern that delivers fast, aggressive cutting action on both push and draw strokes. It is fitted with a tang for use with a standard file handle. Trade machinists, toolroom technicians, and maintenance mechanics are the typical installers and users of this tool.

This file is intended for applications involving taps and milling cutters, where a triangular profile is needed to access tight corners and angular surfaces. It is appropriate for bench work in machine shops, maintenance facilities, and fabrication environments. The 8-inch length provides enough control and leverage for detailed hand-filing tasks on both production and repair work. The bastard cut grade positions this file between smooth and coarse, making it a practical general-purpose choice for light to moderate deburring and sharpening operations.

Installation Notes

This file is a hand tool used by machinists and maintenance technicians during bench work operations. Always fit a properly sized handle onto the tang before use to prevent hand injury from the exposed tang point. Secure the workpiece in a vise before filing to maintain control and consistent stroke angle. Inspect the file for cracks or damaged teeth before each use and clean with a file card regularly to prevent pinning and maintain cutting efficiency.
