Polycrystalline Diamond is a diamond combo produced by diamond sintered with bond under high temperature and high pressure;It has very high wear ability and high thermal stability. 
TSP series is the ideal material for petroleum and geological drilling bits since it has high wear resistance and much lower price compared to genuine diamond. 
TSP Series has higher wear ability than PCD Series.Compared to genuine diamond ,it not only has much high grinding efficiency ,but the price is much lower.Therefore, it is the first choice for demand processing nowadays.The engineers of 3U corp .Can control the wear ability of polycrystalline diamond accurately for different Industrial purposes.
