Graphite Square End Mill【2 Flutes Long Neck Square Φ 0.2-3】

2-Flute Long-Neck Flat-End Diamond-Coated End Mill – Precision Tool for Graphite and Ceramic Machining

Engineered for high-hardness, brittle non-metallic materials such as graphite and technical ceramics, this 2-flute long-neck carbide end mill features a high-performance diamond coating, delivering exceptional wear resistance, dimensional stability, and surface finish quality. Tested tool life exceeds 18 hours under dry cutting or MQL conditions in CNC machining centers.

High-Adhesion Diamond Coating for Extended Tool Life

The tool is coated with a premium diamond-like carbon layer, offering ultra-high hardness and chemical stability. This significantly reduces tool wear, edge chipping, and thermal degradation—ideal for dry or near-dry machining of abrasive materials.

Long-Neck Design for Deep Cavity and Fine Feature Access
The extended neck geometry allows for easier access to deep cavities, tight areas, and intricate profiles while minimizing tool interference. Perfect for electrode pocketing and fine-feature finishing on ceramic components.

2-Flute Sharp Cutting Edge for Low Cutting Force and Clean Finish
Optimized for high-speed dry cutting, the dual-flute design reduces cutting resistance and heat generation. It helps minimize edge chipping in ceramics and preserves fine corners in graphite, resulting in cleaner cuts and improved surface integrity.

Ultra-Fine Grain Carbide Substrate for Strength and Stability
Built from high-strength micro-grain carbide, the tool offers excellent hardness and fracture resistance. This ensures stability during demanding operations on brittle or abrasive materials.

CNC Ground with ±0.01mm Tolerance for Precision Applications
Manufactured using advanced 5-axis CNC grinding, each tool maintains tight dimensional tolerances and consistent geometry. Suitable for graphite mold machining, ceramic structural parts, and precision electrode finishing.
