2-Flute Long-Neck Ball-End Diamond-Coated End Mill

Precision Tool for Machining Graphite & Ceramic Materials

Engineered for high-hardness, brittle non-metallic materials such as graphite and electrical ceramics, this 2-flute long-neck ball-end carbide end mill features a high-adhesion diamond coating. It offers outstanding wear resistance, thermal stability, and surface finish. Proven in real-world dry and MQL conditions, the tool consistently delivers a service life of over 18 hours, making it ideal for high-efficiency CNC machining applications.

High-Hardness Diamond Coating for Extended Tool Life
Utilizes a high-adhesion diamond coating with exceptional hardness and chemical stability. This layer effectively resists abrasive graphite dust and edge micro-chipping, ensuring long-lasting performance in dry machining environments.

Long-Neck Design for Deep Cavity and Complex Part Access
The extended neck geometry allows improved reach into deep cavities and narrow features while minimizing interference. Ideal for machining graphite molds, electrode undercuts, ceramic components, and other geometrically complex parts with high precision.

2-Flute Ball-Nose Geometry for 3D Contours & Smooth Finishes
Perfect for freeform surfaces, 3D cavities, and fillets, the ball-end profile supports continuous cutting with reduced tool marks. Delivers superior surface integrity, especially on curved or contoured features.

Ultrafine-Grain Carbide Substrate for Strength & Crack Resistance
Manufactured from premium ultrafine-grain carbide, the tool body combines high hardness with excellent resistance to thermal cracking—critical for machining abrasive and brittle materials like graphite and ceramics.

5-Axis CNC Precision Grinding with Tight Tolerances
Each tool is precision-ground using advanced 5-axis CNC grinding technology, with dimensional tolerances controlled to within ±0.01 mm. This ensures consistent performance in applications demanding tight geometric and positional accuracy, including graphite electrodes, ceramic molds, and microstructure components.
