Apex Tool Group Llc 21853 Round Bastard File 8 Inches

Product Description

The APEX TOOL GROUP LLC 21853 is an 8-inch round bastard file designed for shaping, enlarging, and smoothing circular openings and concave surfaces. Manufactured to American pattern standards, it features a single-cut tooth configuration and a slight taper toward the point for controlled material removal. The Black Diamond cutting surface delivers consistent bite across ferrous and non-ferrous metals. This file is a standard hand tool used by machinists, pipefitters, HVAC technicians, and general trade professionals who need precise filing in curved or round profiles.

This file is suited for applications where a flat or half-round file cannot follow the workpiece geometry, such as deburring pipe ends, enlarging drilled holes, fitting curved mating surfaces, or finishing cast metal components. At 8 inches in length, it is appropriate for bench work and field use across residential and light commercial trade settings. It is sold individually and packaged on a card for point-of-sale storage.

Key Features

• Round cross-section targets circular openings and concave surfaces directly
• Single-cut tooth pattern provides smooth, controlled stock removal
• American pattern construction conforms to standard file geometry and cut angles
• Slight taper toward the point allows access to narrow or restricted areas
• Black Diamond cutting surface for consistent performance on metal workpieces
• Carded packaging for organized tool storage and retail display

Compatibility

Designed as a general-purpose round bastard file suitable for hand-filing applications across metalworking, pipefitting, and mechanical trade work where a round profile is required.

Installation Notes

Round files are used by hand without power equipment. Secure the workpiece firmly in a vise before filing to prevent movement and maintain control. Always file on the forward stroke and lift on the return to preserve cutting tooth life. Inspect the tang end before use and ensure a properly fitted handle is installed to prevent hand injury.
