Diamond coating end mills are engineered for superior performance in machining highly abrasive, non-ferrous, and composite materials. With an ultra-hard diamond coating, these cutting tools deliver exceptional wear resistance, extended tool life, and unmatched precision-making them ideal for aerospace, automotive, electronics, and advanced material manufacturing.
Whether you're working with carbon fiber, graphite, ceramics, or high-silicon aluminum, our diamond-coated end mills ensure smooth finishes, reduced tool wear, and increased productivity.
Chemical Vapor Deposition (CVD) Diamond Coating ensures extreme hardness (up to 10,000 HV) and superior abrasion resistance.
Reduced Friction & Heat Buildup - The diamond coating minimizes heat generation, preventing premature tool failure.
Longer Tool Life - Outlasts standard carbide and TiAlN-coated end mills in abrasive applications.
Sharp Cutting Edges maintain tight tolerances and fine surface finishes.
Optimized Geometry for efficient chip evacuation, reducing edge chipping and workpiece damage.
Available in 2-Flute, 3-Flute, and 4-Flute Designs for varying material removal rates and finish requirements.
Best for Machining:
Graphite & Carbon Fiber
Fiberglass & CFRP/GFRP
High-Silicon Aluminum & Metal Matrix Composites (MMC)
Ceramics & Advanced Engineering Plastics
Avoid Ferrous Metals - Diamond reacts chemically with iron, making it unsuitable for steel machining.
Microcrystalline Diamond (MCD) - Best for fine finishes and high precision.
Nanocrystalline Diamond (NCD) - Improved toughness for interrupted cuts.
Diamond-Like Carbon (DLC) - Alternative for specific composite applications.
End Mill Types: Square, Ball Nose, Corner Radius
Shank Types: Straight, Tapered, Weldon Flat
Coatings: Pure Diamond, Diamond Composite, Multi-Layer Coatings
Machining carbon fiber reinforced polymers (CFRP) for aircraft components.
High-speed milling of titanium and aluminum alloys with diamond-coated tools.
Precision machining of brake discs, pistons, and engine components from MMC materials.
Carbon fiber body parts milling for high-performance vehicles.
Graphite electrode machining for EDM applications.
Ceramic substrate milling for circuit boards and sensors.
Machining biocompatible composites and ceramic implants with ultra-fine finishes.
Optics, mold & die making, and composite prototyping with high dimensional accuracy.
Extended Tool Life - Up to 10x longer than uncoated carbide end mills in abrasive materials.
Higher Cutting Speeds - Diamond coating allows for increased RPM without compromising tool integrity.
Consistent Performance - Maintain sharpness and precision over prolonged use.
Cost-Effective - Reduced tool changes and downtime lead to lower machining costs per part.
Custom Solutions Available - Tailored geometries, coatings, and sizes for specialized applications.

Use Coolant When Possible - Though diamond-coated tools resist heat, coolant extends life in high-speed operations.
Avoid Interrupted Cuts in Hard Materials - Can cause micro-chipping; use stable setups.
Proper Storage - Keep in dry, vibration-free conditions to prevent coating damage.
Regular Inspection - Check for wear or chipping to maintain optimal performance.
