Polycrystalline Diamond Compact (PDC), is a super hard composite material synthesized a layer of selected diamond particles and bonded to a tungsten carbide substrate. Combining the properties of both super hardness and abrasion resistance of diamond with outstanding strength and toughness of tungsten carbide.

Geological exploration, coalfield mining, water well drilling and water conservancy and hydropower, etc.

Diamond with Tungsten Carbide.

PDC cutter used for drilling bits:
1) The PDC for drilling bits is applicable to all sorts of geological.

2) We can offer PDC with different claw structures and chamfer types whether or not grinding an polishing.

3) We can supply PDC with special shape and size based on customers’ orders.

4) The PDC for tools is used in processing alloy, non-metal and metal with high rigidity. According to the customers’ demands, we can provide PDC of different shapes, such as rectangle shape, triangle shape, sector shape, etc.

Main Advantages:
1) High wear resistance.

2) High impact resistance.

3) High thermal stability.

4) High density (low porosity)

5) High compositional & structural homogeneity.

6) Excellent bonding between diamond particles.

7) Optimized interface between diamond and tungsten-carbide layers for excellent binding.

8) Best general performance available in the market.
