Graphite Square End Mill【4 Flutes Φ 1-12】

4-Flute Flat Head Diamond Coated End Mill – Precision Tool for Graphite and Ceramic Machining

Specifically designed for machining high-hardness, highly abrasive non-metallic materials such as graphite and electrical ceramics, this 4-flute flat end mill features a high-performance diamond coating for superior wear resistance, cutting stability, and surface finish. Ideal for high-efficiency, high-precision dry cutting applications.

Ultra-Hard Diamond Coating for Extended Tool Life
The tool is coated with premium diamond, offering a surface hardness of HV9000 or higher. This significantly increases wear resistance and allows for long tool life, even in the continuous dry machining of abrasive materials like graphite and ceramics.

4-Flute Design for Improved Rigidity and High-Speed Performance
The multi-flute configuration enhances overall rigidity and vibration resistance. It enables stable, high-efficiency operations during side milling, face finishing, and surface cleanup—particularly in graphite electrode machining—while maintaining dimensional accuracy.

Flat End Geometry for Clean Edges and Precise Finishes
The flat head design ensures accurate end face control and crisp edge definition, making it ideal for contour milling of molds, outer profiles of electrodes, and flat surfaces of ceramic structural components.

Ultra-Fine Grain Carbide Substrate for Crack Resistance
Built from ultra-fine grain carbide, the tool resists thermal cracking and fracture, providing excellent performance under the high-stress conditions often encountered in brittle material machining.

CNC Precision Ground, ±0.01mm Tolerance
Each tool is ground with tight tolerance control to ensure consistent dimensional accuracy. Perfect for high-precision applications such as graphite electrodes, ceramic inserts, and micro-structural parts with strict geometric tolerances.
