Value Collection 2152C Half Round Needle Diamond File

Product Description

The VALUE COLLECTION 2152C is a coarse-grade half round needle diamond file designed for precision material removal in tight spaces and contoured surfaces. With an overall length of 5.5 inches and a length of cut of 2.75 inches, this file delivers controlled abrasion on hardened materials including carbide, ceramics, glass, and hardened steel. The half round profile provides two working surfaces in one tool: a flat face for flat or convex work and a curved face for concave recesses and holes. Machinists, tool-and-die workers, and maintenance technicians reach for needle files when standard hand files lack the access or the precision a job demands.

This file is suited for deburring, honing, and fine-fitting operations on hardened components that standard cut files cannot address. The coarse grade makes it effective for faster stock removal on hard substrates before stepping down to finer grits. Typical applications include finishing keyways, deburring drilled holes, fitting mating metal parts, and sharpening tool edges. The needle-style form factor makes it practical for die work, mold fitting, and instrument repair where access is restricted to narrow openings.

Key Features

• Half round profile provides a flat face and a curved face for versatile filing on multiple surface geometries
• Coarse diamond grade removes material faster on carbide, ceramics, and hardened steel
• Needle-style form for access in tight recesses, slots, and small openings
• 2.75-inch length of cut concentrates the abrasive surface where it matters
• Compact 5.5-inch overall length suits bench work and close-tolerance hand filing

Compatibility

Designed as a general-purpose needle diamond file suitable for use on hardened metals, carbide, ceramics, glass, and similar hard materials where conventional cut files are not effective.

Installation Notes

Hand files are used by machinists, toolmakers, and maintenance technicians without power tools. Secure the workpiece firmly in a vise or fixture before filing to prevent movement and maintain control. Apply consistent, even pressure on the forward stroke and lift or ease pressure on the return stroke to preserve the abrasive surface. Inspect the file periodically for loading and clean with a file card or brush as needed.
