Graphite Corner Radius End Mill【4 Flutes Φ 3-12】

4-Flute Corner Radius Diamond Coated End Mill — Optimized for High-Precision Machining of Graphite and Ceramics

Engineered specifically for high-hardness, brittle non-metallic materials such as graphite and technical ceramics, this 4-flute corner radius end mill features a high-adhesion diamond coating that delivers outstanding wear resistance and thermal stability. Designed for high-efficiency applications in CNC machining centers, this tool excels in both dry cutting and MQL environments. Verified tool life exceeds 18 hours in continuous cutting scenarios.

Premium Diamond Coating for Extended Tool Life
Utilizes a high-adhesion diamond coating that offers extreme surface hardness and chemical stability. Effectively resists abrasion from graphite dust and impact damage when machining ceramics, delivering long-lasting performance under harsh conditions.

Corner Radius Geometry for Superior Edge Strength & Finish Quality
Rounded cutting edges minimize stress concentration and enhance edge strength, helping to prevent micro-chipping and cracks—ideal for precision contouring, cavity finishing, and fine-detail machining of brittle materials.

4-Flute Design for Rigidity and High-Efficiency Cutting
The multi-flute layout increases tool stiffness and reduces vibration, enabling higher feed rates and improved surface finish. Perfect for side milling, face milling, and finishing operations on graphite electrodes and ceramic components.

Ultrafine Carbide Substrate for Toughness and Crack Resistance
Made from ultrafine-grain solid carbide, the tool offers a balanced combination of hardness and toughness. It resists thermal cracking and edge failure during prolonged exposure to abrasive materials.

Precision Ground to ±0.01mm Tolerance on 5-Axis CNC
Manufactured with advanced 5-axis CNC grinding technology to ensure tight dimensional control and consistency. Ideal for applications requiring high geometric accuracy and repeatability, including graphite molds, ceramic inserts, and structural parts.
