Import Domed Type Pdc Cutter — Buy in Bulk from Supplier in China

The Domed Type PDC Cutter from Zhengzhou More Superhard Company is a polycrystalline diamond compact cutting element designed for rotary drill bits used in hard rock and medium-hard rock applications. Available in standard sizes including 0808, 1004, 1204, 1613, and 1919, these cutters feature a flat, sharp-edged, or cambered profile optimized for controlled rock fragmentation. The diamond layer thickness and tungsten carbide substrate composition are engineered to balance wear resistance and impact tolerance under variable drilling conditions.

These cutters are manufactured using high-pressure, high-temperature sintering of synthetic diamond grit on a tungsten carbide substrate, a standard industrial process for PDC elements. The diamond layer typically measures between 0.5mm and 1.2mm in thickness, depending on size and intended application. Substrate hardness ranges from HRA 88 to HRA 91, consistent with industry norms for drill bit inserts used in oil and gas or geological exploration. The absence of visible porosity or delamination in the diamond-carbide interface indicates standard quality control for this product class.

They are primarily purchased by drill bit manufacturers serving coal mining, oil and gas drilling, and hard rock geological survey sectors. Buyers commonly specify these cutters for applications requiring high abrasion resistance in abrasive formations such as quartzite or basalt. Packaging is typically in protective foam-lined boxes, with batch quantities of 100 to 500 pieces per order. Lead time and incoterms are confirmed directly with the supplier, as no fixed terms are published.
