CVD DIAMOND DRILL BITS

Precision Drilling, Diamond-Grade Performance

We specialize in the research, development, and manufacture of CVD (chemical vapor deposition) diamond drill bits. Leveraging the unmatched hardness and structural advantages of single-crystal and polycrystalline CVD diamond, we provide high-precision drilling solutions for the semiconductor, precision manufacturing, and advanced electronics industries.

WHY CVD DIAMOND DRILL BITS

Why Choose CVD Diamond Drill Bits

Diamond is the hardest material found in nature, while CVD technology enables precise control over the diamond's lattice structure and purity. Compared with conventional carbide or natural diamond drill bits, CVD diamond drill bits offer:

Grain-Free Structure: Single-crystal CVD diamond contains no grain-boundary defects, allowing exceptionally sharp cutting edges and delivering superior hole-wall surface finish

Exceptional Service Life: Extremely high hardness and wear resistance significantly reduce tool replacement frequency and production-line downtime costs

Excellent Thermal Conductivity: Rapidly dissipates heat generated by drilling friction, reducing material damage caused by thermal stress

Consistent Hole-Diameter Accuracy: Maintains consistent hole-diameter tolerances in both micro-hole and deep-hole machining, meeting the yield requirements of advanced processes

APPLICATIONS

Applications

Precision drilling of semiconductor wafers and substrates (advanced packaging applications such as TSV and package substrates)

Micro-hole drilling for high-density interconnect printed circuit boards (HDI PCB)

Drilling of hard and brittle materials, including silicon, silicon carbide, aluminum nitride, nitride-based materials, advanced ceramics, sapphire, and optical glass

PROCESS CAPABILITY

Our Process Capabilities

From diamond blank growth, laser cutting-edge shaping, and metallization to precision brazing and quality inspection, we provide one-stop CVD diamond drill-bit manufacturing services. We can also develop customized dimensions and hole specifications according to customer requirements.
