Micro End Mills

Micro End Mills

Our company specializes in the research, development, and manufacturing of high-precision micro end mills, expertly engineered for the most demanding micromachining applications. Designed for intricate contouring, fine slotting, detailed profiling, and precision 3D surface machining, our micro end mills deliver unmatched accuracy and surface finish in the production of miniature and complex components.

Fabricated from ultra-fine grain tungsten steel (solid carbide), our micro end mills provide superior hardness, rigidity, and resistance to chipping—even at extremely small diameters down to 0.1mm. This advanced substrate ensures dimensional stability and long tool life under high-speed cutting conditions. To further enhance performance, each tool is coated with advanced composite coatings such as AlTiN, TiAlN, or specialized multi-layer coatings, which significantly improve wear resistance, reduce friction, and withstand elevated temperatures generated during high-RPM operations.

The precision-ground cutting edges, optimized helical flute geometry, and carefully balanced design contribute to minimal vibration, excellent chip evacuation, and consistent cutting performance. With tight tolerance control and superior concentricity, our micro end mills achieve minimal runout, enabling ultra-precise material removal in both roughing and finishing stages. This results in clean edges, smooth surface finishes, and exceptional detail reproduction—critical for high-accuracy applications.

These micro end mills are ideal for machining small, complex parts across a wide range of materials, including carbon steel, stainless steel, copper alloys, brass, aluminum alloys, titanium, and heat-resistant superalloys. They are widely used in industries where precision is non-negotiable, such as medical device manufacturing (e.g., surgical tools, implants), electronics (connectors, housings), aerospace components (fuel system parts, sensors), mold & die making (micro-cores and cavities), and optical instrument fabrication.

Compatible with high-speed CNC machines, 5-axis machining centers, and automated micromachining systems, our micro end mills offer excellent repeatability and process reliability. Whether performing delicate finishing passes or efficient micro-scale roughing, they deliver consistent performance and extended tool life, reducing downtime and improving overall productivity.

Backed by rigorous quality control, cutting-edge grinding technology, and continuous innovation, our micro end mills represent the pinnacle of precision tooling. Choose our micro end mills for exceptional sharpness, durability, and accuracy—empowering your success in the most challenging micro-machining tasks.
