Graphite Ball Nose End Mill【2 Flutes R0.5-R6】

2-Flute Ball Nose Diamond-Coated End Mill – Engineered for High-Precision Machining of Graphite and Ceramics

Specifically designed for hard and brittle non-metallic materials such as graphite and electroceramics, this 2-flute ball nose end mill features a high-adhesion diamond coating. It delivers excellent wear resistance, thermal stability, and superior surface finish. Proven in-field tool life exceeds 18 hours, making it ideal for dry machining and MQL applications on CNC machining centers.

High-Adhesion Diamond Coating for Exceptional Wear Resistance
Engineered with a durable diamond coating that offers extreme hardness and chemical inertness. This coating effectively resists graphite particle abrasion and prevents edge micro-chipping under dry cutting conditions, significantly extending tool life.

Ball Nose Geometry – Ideal for 3D Contours and Mold Cavities
The spherical tip design is optimized for complex 3D profiles, internal corner transitions, and cavity milling. It ensures a smooth surface finish with minimal tool marks, ideal for fine detail work in graphite molds and ceramic components.

2-Flute Design Reduces Cutting Load and Heat Buildup
Sharp dual-flute geometry enables efficient chip evacuation, reduces cutting resistance, and minimizes heat accumulation—helping to prevent thermal cracking and maintain material integrity during high-speed machining.

Ultra-Fine Carbide Substrate – Superior Fracture and Thermal Resistance
Constructed from high-strength micro-grain carbide, the tool provides excellent toughness and crack resistance, making it suitable for extended use in abrasive environments like graphite and ceramics.

Precision CNC Ground – ±0.01mm Dimensional Tolerance
Manufactured using advanced 5-axis CNC grinding technology, ensuring exceptional dimensional accuracy and repeatability. Ideal for high-precision applications such as graphite electrodes, ceramic inserts, and complex mold geometry.
