Value Collection 2172M Knife Needle Diamond File Medium

Product Description

The VALUE COLLECTION 2172M is a knife-style needle diamond file designed for precision material removal in tight spaces and fine-detail work. The knife profile allows access to narrow slots, notches, and angled surfaces where standard files cannot reach. The medium-grade diamond abrasive surface delivers controlled stock removal on hard materials including hardened steel, carbide, ceramics, and glass. At 5.5 inches overall length with a 2.75-inch length of cut, it is sized for one-hand control during close-tolerance filing work. Machinists, toolmakers, and maintenance technicians are the primary users of this file type.

This diamond needle file is suited for benchtop and field use across metalworking, toolmaking, mold and die work, and precision maintenance applications. The knife cross-section is particularly effective for filing keyways, dovetails, V-grooves, and narrow internal angles. At 0.1875 inches wide and 0.0625 inches thick, it fits into confined geometry that flat or round needle files cannot address. It performs on non-ferrous metals, composites, and other hard, abrasive-resistant materials in addition to hardened steel.

Key Features

• Knife-profile needle file for access to narrow slots, grooves, and angled recesses
• Medium diamond abrasive grade for controlled material removal without aggressive overcut
• 2.75-inch length of cut provides usable working surface in a compact tool
• 5.5-inch overall length sized for one-hand control and precision handling
• 3/16-inch width and 1/16-inch thickness allow entry into tight, confined geometry
• Diamond abrasive surface works on hardened steel, carbide, ceramics, and glass

Compatibility

Designed as a general-purpose knife needle diamond file suited for benchtop and portable use in metalworking, toolmaking, and precision maintenance applications where a medium-grade diamond abrasive file is required.

Installation Notes

This file is a hand tool requiring no power source or installation. Apply consistent, moderate pressure during use and allow the diamond abrasive to do the cutting — excessive force accelerates wear on the abrasive surface. Keep the file clean of metal filings using a file card or brass brush to maintain cutting efficiency. Eye protection is recommended during all filing operations.
