Product Overview
rafted from high-grade tungsten carbide, this tool is engineered to handle hard materials up to 65HRC, featuring advanced nano coating technology and edge passivation treatment to resist wear and extend service life. Its ultra-small diameter range (0.2mm-0.9mm) makes it perfect for micro-machining in automotive molds, plastic processing, and precision engineering, with full OBM/ODM/OEM support to meet unique customer needs.

Material & Coating Advantages
Nano Coating Technology: Multilayer nano coatings significantly boost surface hardness and wear resistance, enabling stable cutting of HRC65 materials without frequent tool changes.
High-Grade Tungsten Carbide: Ensures exceptional tool strength and durability, even when machining high-hardness substrates, reducing downtime and replacement costs.
Multilayer Film Coating: Adds a heat-resistant barrier, protecting the tool from high temperatures generated during high-speed micro-milling.
Design & Manufacturing Highlights
Edge Passivation Treatment: Smooths tool edges to prevent cracking and chipping, extending service life and reducing machining errors in ultra-precise tasks.
German Walther Equipment Production: Uses imported German Walther CNC machines to achieve ±0.001mm precision, guaranteeing consistent tool performance and reliability.
2 Flutes Design: Optimizes chip flow for ultra-small diameters, minimizing material buildup and ensuring clean, burr-free cuts in intricate applications.
0.2mm-0.9mm Micro Diameter Range: Covers ultra-fine machining needs, perfect for producing intricate parts like mold inserts, micro-components, and precision fixtures.
