Value Collection 2172C Knife Needle Diamond File Coarse

Product Description

The VALUE COLLECTION 2172C is a knife-style needle diamond file designed for precision material removal in tight spaces and detailed finishing work. The knife profile — 3/16 inches wide and 1/16 inches thick — allows access to narrow slots, grooves, and angular surfaces where standard files cannot reach. With a 2-3/4 inch length of cut and a 5-1/2 inch overall length, this file delivers controlled coarse-grade abrasion suitable for deburring, sharpening, and shaping hard materials including hardened steel, carbide, ceramic, and composites. Machinists, toolmakers, and maintenance technicians keep needle files like this on hand for detail work on tooling, dies, and precision components.

This file is appropriate for bench work and field maintenance tasks that require a fine-profile abrasive tool. The coarse grade removes material efficiently, making it useful for initial shaping passes before stepping down to finer grits. Typical applications include cleaning up weld seams in narrow joints, filing keyways, dressing carbide tooling edges, and opening tight-tolerance slots. The compact needle form factor makes it well suited to work in confined areas on mechanical assemblies, fixtures, and fabricated parts.

Key Features

• Knife profile for access to narrow grooves, slots, and angular surfaces
• Coarse grade for efficient initial material removal and shaping passes
• 2-3/4 inch length of cut provides usable abrasive surface in a compact form
• 3/16 inch wide by 1/16 inch thick cross-section suits tight-tolerance detail work
• 5-1/2 inch overall length for comfortable hand control during precision filing
• Diamond abrasive construction handles hardened steel, carbide, ceramic, and similar hard materials

Compatibility

Designed as a general-purpose needle file for hand filing applications on hard materials in machining, toolmaking, and maintenance environments.

Installation Notes

Needle files are hand tools used without power equipment — apply consistent, moderate hand pressure during use. Secure the workpiece in a vise or fixture before filing to maintain control and avoid injury. Inspect the file surface before use and replace if the diamond abrasive shows significant wear or loading, as a worn file increases the risk of slipping on the workpiece. Store separately from other tools to protect the abrasive surface from damage.
