Apex Tool Group Llc 21854 Round Bastard File 10 Inches

Product Description

The APEX TOOL GROUP LLC 21854 is a 10-inch round bastard file designed for filing circular openings and concave surfaces in metal, wood, and other materials. Manufactured under the Nicholson Black Diamond line, this file features a single-cut, American pattern tooth configuration and tapers slightly toward the point for controlled material removal in tight or curved profiles. The bastard cut provides a medium-coarse aggressiveness suited to general-purpose stock removal. It is a standard hand tool used by machinists, pipefitters, plumbers, and HVAC technicians for deburring, shaping, and fitting work.

This file is well suited for trade and shop applications where round or curved surfaces need to be dressed, enlarged, or smoothed. Typical use cases include enlarging pipe knockouts, fitting conduit openings, shaping sheet metal edges, and deburring cast or machined bores. The tapered profile allows the file to reach into confined openings and work progressively through a range of diameters along its length. It is sold as a single unit and is appropriate for both bench work and field service use.

Installation Notes

Hand files require no power source but should be fitted with an appropriate handle before use to prevent injury from the tang. Always wear safety glasses when filing metal to protect against metal particles and debris. Inspect the file for cracks or missing teeth before use. Store files separated from other tools to protect the cutting teeth from damage.
