Composite machining

Machining composite materials is a battle between unpredictable forces, heat sensitivity and rapid tool wear. For successful machining, sharp and controlled cutting is required to avoid delamination and vibration.

CoroMill® Plura composite offers a range of tools optimized for these challenging materials. Grades are specialized for each application area and optimized for long tool life and high productivity.

You can expect consistent and high-quality results across a wide range of cutting conditions with reduced vibration and a comfortable sound level for a better working environment.

Built for composite challenges
Grade O2AD

Grade O2AD combines a CVD diamond coating with a tailored substrate, creating a solution with exceptional durability and precision optimized for demanding composite applications.

Key features:

  • Advanced CVD diamond coating for exceptional abrasive wear resistance
  • Dedicated substrate, tailored for diamond coating, enabling great adhesion between substrate and coating material

This pairing ensures a cutting edge with best-in-class performance and cutting quality, with proven reliability and extended tool life in composite milling.


CoroMill Plura composite cutting tools

Application recommendations, 2P350

  • Apply up milling
  • Recommended tool diameter is 0.5×DC < APMX* <1.5×DC

*Depending on the diameter, APMX can be increased for DC>10 mm (0.394 inch), stability and clamping are crucial


  • Always machine with minimum overhang


  • Multiply tool life by working in different levels
