Key Features & Benefits

1. Ultra-Hard Diamond Coating for Maximum Wear Resistance

• 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.

2. Precision Machining for High-Quality Finishes

• 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.

3. Superior Performance in Non-Ferrous & Composite Materials

• 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.

4. Multiple Coating Options for Enhanced Performance

• 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.

5. Wide Range of Configurations

• End Mill Types: Square, Ball Nose, Corner Radius

• Shank Types: Straight, Tapered, Weldon Flat

• Coatings: Pure Diamond, Diamond Composite, Multi-Layer Coatings

 

Applications & Industries

1. Aerospace & Defense

• Machining carbon fiber reinforced polymers (CFRP) for aircraft components.

• High-speed milling of titanium and aluminum alloys with diamond-coated tools.

2. Automotive & Motorsports

• Precision machining of brake discs, pistons, and engine components from MMC materials.

• Carbon fiber body parts milling for high-performance vehicles.

3. Electronics & Semiconductor Manufacturing

Maintenance & Handling Tips

• 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.
