What is PDC cutter?

Polycrystalline diamond compact consists of a layer of polycrystalline diamond and a tungsten carbide alloy matrix. It is made by sintering the fine diamond powder and the cemented carbide matrix at the same time under high pressure and high temperature (about 60,000 atmospheres, 1400-1500℃). Diamond composite bit (PDC bit) suitable for drilling in various formations. The D-D bond between the diamond grains in the polycrystalline diamond layer makes the diamond layer have high hardness, high strength and high wear resistance, and has good self-sharpness. Diamond composite sheet can be used in oil drilling, geological exploration, coal drilling bits and machining tools and other industries.

Drilling and mining diamond cutters are suitable for soft to medium hard geological drilling, with high impact toughness and thermal stability, heat resistance temperature up to 700(two minutes), such products have a plane and a variety of groove surface combination type, and can be designed to grinding type , polishing type , chamfering type, etc  according to user needs.
