PCD (Polycrystalline Diamond) and PCBN (Polycrystalline Boron Nitride) are two types of cutting tools commonly used in machining applications.

PCD tooling is made from diamond particles sintered together under high pressure and temperature. It is used for machining materials such as concrete, asphalt, rock, and stone. PCD tooling is highly wear-resistant and can withstand high temperatures, making it an excellent choice for machining hard materials.

PCBN tooling is made from a combination of diamond and boron nitride particles sintered together under high pressure and temperature. It is used for machining materials such as cast iron, hardened steel, and ceramics. PCBN tooling offers excellent wear resistance and can withstand high temperatures, making it suitable for machining hard materials.

Both PCD and PCBN tooling provide efficient cutting with low wear rates and are commonly used in industries such as construction, mining, automotive, aerospace, and mold manufacturing.
