PCD End Mill High Hardness Non-metallic Special Purpose
The PC810D series end mills combine strength and superior performance. These professional-grade end mills are specifically designed for machining difficult-to-machine non-metallic materials such as ceramics, graphite, and high-hardness composites. They feature a 4-flute, 5° clearance angle, and polycrystalline diamond (PCD) cutting edge design. Equipped with a carbide shank, they offer ultra-high hardness, exceptional wear resistance, and a mirror-like finish, making them an ideal choice for precision machining in industries such as new energy, semiconductors, and optics. They provide superior performance for machining high-hardness non-metallic materials. This tool features an eccentric removal function to achieve maximum edge strength, improving performance in hard materials and making it a good choice for various applications.

Design details engineered for accuracy, tool life and process stability.
Symmetrically distributed four flutes evenly distribute cutting force, improving vibration suppression by 40% and achieving a surface finish of Ra 0.2μm or less, resulting in a mirror-like effect.
With a hardness of HV10000, 8-10 times that of cemented carbide, and 10-20 times better wear resistance, significantly extending tool life compared to cemented carbide tools.
Optimized small clearance angle cutting edge reduces tool-workpiece friction, lowering the risk of machining chatter marks, especially suitable for finishing brittle materials such as ceramics and graphite.
Utilizes cemented carbide with a grain size ≤0.8μm, offering excellent rigidity and high bending strength, suitable for high-feed machining requirements.
The cutting edge radius is precisely controlled at 0.005mm, balancing sharpness and chipping resistance, adapting to the cutting needs of brittle materials.
Utilizing vacuum high-temperature brazing technology, the PCD cutting edge and tool holder achieve high bonding strength, excellent impact resistance, and prevent cutting edge detachment.
The tool surface is mirror-polished, resulting in a friction coefficient as low as 0.22, effectively suppressing chip adhesion and preventing workpiece scratches.
