Apex Tool Group Llc 21858N Half Round Bastard File 10 in

Product Description

The APEX TOOL GROUP LLC 21858N is a 10-inch half round bastard file designed for shaping, smoothing, and deburring metal and other materials across concave, convex, and flat surfaces. One side is rounded and the other is flat, giving the technician two working profiles in a single tool. The backs are double cut, which means the file removes material efficiently on both the push and draw strokes. This is an American pattern file, a standard configuration recognized across trade and industrial applications.

The 21858N is suited for metal fabrication, pipefitting, HVAC ductwork fitting, and general maintenance tasks where a versatile filing profile is required. The half round geometry makes it particularly useful when working inside curved pipe ends, fittings, or machined recesses where a flat file cannot reach. It is sold in a package of 6 units, making it practical for shop stock or tool crib replenishment.

Key Features

• 10-inch length provides good leverage and stroke length for medium to heavy filing work
• Half round profile covers concave, convex, and flat surfaces with one tool
• Double cut backs increase material removal rate on both sides of the file
• American pattern construction meets widely recognized trade standards
• Packaged in quantities of 6 for efficient stocking

Compatibility

Designed as a general-purpose hand file suitable for use on ferrous metals, non-ferrous metals, and similar hard materials in trade and industrial maintenance applications.

Installation Notes

Hand files are used by machinists, pipefitters, HVAC technicians, and general maintenance trades. Always secure the workpiece in a vise before filing to prevent movement and injury. Inspect the file handle for cracks or looseness before use, and never use a file without a properly fitted handle. Files should not be used on hardened steel surfaces that exceed the file's hardness rating, as this will damage the teeth and reduce tool life.
