Are PCD Products Right For You?

PCD is a composite of diamond particles that are sintered under extreme pressure and temperatures to create a variety of products that are particularly suitable for cutting tools of non-ferrous metals and non-metallic materials, including the wear parts of various equipment.

PCD-tipped tools are ideal for cutting abrasive and wear-resistant materials, including:

  • Aluminum & Aluminum Composite Material (ACM)
  • Carbon Fiber
  • Composite Panels
  • Custom Composite Materials
  • Fiberglass
  • High-Pressure Laminates (HPL)
  • Chipboard, Medium-Density Fiberboard (MDF), Particle Board and High-Density Fiberboard (HDF)

With Eagle’s experienced team of application engineers, you can discuss your unique projects directly with live support to help guide you through the process of picking the PCD formulation that fits you best.

What About PCBN?

PCBN products got through a very similar manufacturing process, but CBN particles are used in place of diamond, making PCBN ideal for ferrous materials – typically a form of steel – used in cutting, drilling and milling tools.

Both PCD and PCBN show excellent wear characteristics and offer unparalleled performance in terms of thermal hardiness, toughness and stability over the life of the toughest projects.

What People Are Saying


“Eagle Superabrasives has always come through for us with competitive pricing and great customer service. If they don’t have the exact grinding wheel that we need, they will customize a wheel for our end-user’s needs and create a new part number for it. I wish I had discovered Eagle SA years ago.”
