Apex 37891 Knife Needle File 6.25 Inches Steel

Product Description

The APEX 37891 is a knife-shaped needle file with cut edges, designed for precise filing and deburring in tight spaces and detailed work areas. Constructed from hardened steel with a hard-stamped marking style, this file delivers consistent material removal on metal, plastic, and similar materials. At 6.25 inches in file length and an overall length of 6.3 inches, it fits comfortably in hand for controlled, fine work. The narrow knife profile — just 0.21 inches wide and 0.06 inches tall — allows access to slots, notches, keyways, and other confined geometry where standard files cannot reach.

Knife needle files are standard bench tools for machinists, pipefitters, electricians, and HVAC technicians performing fitting and finishing work on metal components. The cut-edge design makes this file well suited for sharpening, smoothing weld seams, cleaning up burrs on pipe fittings, and refining metal edges on fabricated parts. It is commonly used in shop and field applications where fine material removal and edge control are required.

Key Features

• Knife shape provides a tapered edge profile for access to narrow slots and angled surfaces
• Cut edges on both faces and the edge for efficient material removal
• Hardened steel construction for durability across repeated use on metal workpieces
• Hard-stamped markings for permanent, legible identification
• Compact 0.21-inch width and 0.06-inch height for work in confined geometry
• Lightweight at 0.02 pounds for extended hand use without fatigue

Compatibility

Designed as a general-purpose knife needle file suitable for use on steel, cast iron, aluminum, copper, and similar materials in trade and shop applications.

Installation Notes

Needle files are hand tools requiring no power source or specialized installation. Secure the workpiece before filing to prevent movement and ensure accurate material removal. Always file with controlled strokes and avoid lateral pressure that can snap thin file stock. Inspect the file tang and handle fit before use to ensure safe, secure grip.
