Sell Polycrystalline diamond PCD for gemstone polishing

Description

1. high hardness, abrasion resistance and impact resistance2. high speed
3. Cutter layout is force balanced to drill a precise round hole and reduce bit whirl
4. Gauge pads have tungsten carbide inserts for maximum wear resistance
5. The diamond layer with thickness over 1 mm increases abrsion resistence of PDC cutter.
6.sintered at high pressure and temperature

Usage : It can be used in making wire-drawing die ,Geological bit,oil bit,
PCD cutting tools,wood cutting tool,and polishing Jewels

PCD is  a diamond combo produced by synthetic diamond sintered with bond under high temperature and high pressure; it has very high wearability and high thermal stability. Its widely used in petroleum extraction, diamond machining, geology drill and mechanical processing tools.
PCD series have lower wearability than TSP series. It is the first choice for nature diamond cutting & polishing nowadays. We can provide different shapes and different sizes of PCD.
