What is Diamond Tooling? (PCD Tooling)

Diamond PCD (polycrystalline diamond) tooling is crafted from a synthetic diamond composite, formed by blending diamond particles with a binder material under high temperature and pressure.

Renowned for its exceptional hardness, toughness, and wear resistance, PCD tooling excels in cutting and machining abrasive materials like composites, aluminum, and other non-ferrous metals. It finds application in various machining tasks such as turning, milling, drilling, and grinding.

Preferred over traditional carbide tooling, diamond PCD tooling offers extended lifespan, higher cutting speeds, and superior surface finishes. Although initial costs may be higher, its long-term performance and durability make it a cost-effective choice.

Why Choose Diamond for Your Cutting Tools?

Diamond is an ideal substance to involve in your industrial processes, especially if you work with non-ferrous materials. Diamond is highly efficient when used in grinding applications, as less heat is generated by diamond tools and the material you grind is less likely to crack or burn. These tools are highly wear-resistant, making them an excellent investment.

We custom-make most of our tools with material sourced locally, so your tool is a custom solution rather than a one-size-fits-most solution. With diamond tools made just for your application, you shouldn’t have to wait long to have a custom solution in your hands and at work for you.

What are the applications of Diamond Tooling?

Polycrystalline Diamond (PCD) can be used to cut non-ferrous materials including, but not limited to:

  • Plastics/Composites
  • Graphite
  • Carbon/Carbon Fiber
  • Aluminum
  • Copper
  • Brass
  • Green Carbide
  • Green Ceramics

Cubic Boron Nitride (CBN) can be used to cut ferrous materials including, but not limited to:

  • Alloy Steels
  • Tool Steels
  • High Speed Steel
  • Inconel

PCD tipped inserts will typically have 25x better tool life than traditional carbide inserts. However PCD inserts are more expensive than carbide inserts, yet over time, tooling cost is reduced due to the longevity of the PCD tools.

Efficient tools = less machine down time. Every-time a carbide insert breaks down, the operator must take time to change out the tooling. PCD tools will prevent machine down time, and even allow the machines to be run "lights out" confidently.

CVD Diamond Coating provides excellent wear resistance and tool life.  Diamond coating has superior tool life improvement over carbide, depending on the grade of coating:

  • ND15: 20x-50x
  • ND10: 20-30x
  • ND5: 6x-8x (Diamond Like Coating)

CVD Diamond Coated endmills and drills also give great surface finish and prevent less edge breaks than carbide.

Diamond Grit Coating is a synthetic diamond compound that is adheard to blanks like wheels, blades, and core drills/hole saws. Grit coating can be applied by using the following methods:

  • Resin Bond
  • Metal Bond
  • Electroplating
  • Brazing

Grit coating is best used for grinding, but can be used for cutting in some applications.
