Brazed PCD Cutting Tool Blanks

Brazed PCD cutting tool blanks represent one of the most mature product forms among composite superhard tool materials. Through the HPHT (High Pressure High Temperature) process, diamond particles and catalysts are directly sintered onto a cemented carbide substrate to form a polycrystalline diamond composite. The PCD layer provides the exceptional wear resistance and isotropic properties of polycrystalline diamond, while the carbide substrate ensures high fracture toughness and excellent brazability. Using laser cutting, the composite can be pre-formed into various insert geometries, offering broad applicability and a high level of customization.

Our brazed PCD cutting tool blanks cover a grain size range from 1 μm to 35 μm, including the F-series for general-purpose applications and the H-series for enhanced wear resistance. The blanks are available with diameters exceeding 55 mm, featuring a uniform, defect-free PCD layer and a mirror-like surface finish. Standard inventory is readily available, and both the PCD layer thickness and overall blank thickness can be customized. Upon request, the blanks can be laser-cut into any insert geometry for direct delivery.
