12-flute Carbide End Mill
The CFM750 series is a professional-grade end mill designed for efficient semi-finishing of carbon fiber reinforced polymer (CFRP) parts. It features a 12-flute, 28° helix angle, diamond coating, and corrugated cutting edge design, housed in a high-rigidity, ultra-fine-grained carbide substrate. Combining exceptional wear resistance, ultra-low cutting resistance, and excellent anti-delamination performance, it is an ideal choice for machining contours, grooves, and holes in carbon fiber parts for industries such as aerospace, new energy, and automotive. It provides an efficient and stable solution for machining CFRP and GFRP parts, making it a good choice for various applications.

Design details engineered for accuracy, tool life and process stability.
Utilizing cemented carbide with a grain size ≤0.8μm and a substrate hardness of HRC65, it combines high rigidity and toughness, offering 55% better chipping resistance than ordinary tools.
Surface hardness HV8000, a friction coefficient as low as 0.15, and wear resistance 12-18 times that of ordinary cemented carbide tools, significantly extending tool life.
The corrugated edge segments the cutting edge, effectively dispersing cutting forces, reducing fiber delamination and tearing, while significantly improving chip removal efficiency and preventing chip clogging.
Enables progressive smooth entry, reducing impact on carbon fiber materials and lowering the risk of machining chatter marks, especially suitable for semi-finish milling and contour machining.
The chip flute space is 35% larger than that of ordinary end mills, improving chip removal efficiency by 40%, preventing chip clogging and secondary scratches on the workpiece.
Plasma-assisted deposition technology improves coating adhesion by 30%, preventing coating peeling during high-speed cutting.
Machining of carbon fiber parts contours and grooves for aerospace and new energy vehicles.
