10Pcs Diamond Needle File Set 3x140mm for 3D Prints & Metal

The 10-Piece Diamond Needle File Set (3mm x 140mm) is an indispensable tool kit designed for makers, engineers, and 3D printing hobbyists. Featuring a high-grade industrial diamond grit electroplated onto high-carbon steel, these files provide exceptional abrasive power and wear resistance. They are specifically engineered to solve the common challenge of post-processing, allowing you to easily clean up support marks, smooth layer lines, and refine tight tolerances on 3D printed parts, custom metal enclosures, and prototype PCBs.

This versatile set includes ten distinct cross-sectional profiles—including flat, semi-circular, triangular, round, and square—enabling you to access complex geometries, internal bores, and intricate slots with ease. Compatible with a wide range of materials such as PLA, ABS, PETG, resin, steel, brass, glass, and carbon fiber, these files feature ergonomic, non-slip dipped handles that ensure comfortable grip and precise control during extended detailing sessions.

Features:

• Industrial Diamond Grit: Electroplated diamond coating ensures long-lasting abrasive performance on hard materials.
• 10-Piece Assorted Profiles: Includes flat, round, half-round, triangular, square, and warding shapes for comprehensive detailing.
• Precision Sizing: 3mm shaft diameter and 140mm total length make them perfect for micro-engineering and tight spaces.
• Ergonomic Dipped Handles: Non-slip red vinyl handles provide excellent grip, comfort, and precise tactile feedback.
• Multi-Material Compatibility: Highly effective on plastics (PLA/ABS/PETG), metals, glass, ceramics, and wood.
• Post-Processing Essential: Ideal for removing 3D print support structures, smoothing parting lines, and deburring metal edges.
