是采用與其它PCD產品相同的超高壓－高溫技術制造的聚晶產品，由于它所用結合劑在高溫時不與金剛石反應且其熱脹系數與金剛石接近，其耐高溫高達攝系1200度，SFTSP主要用于制造地質鉆頭及石油鉆頭等
Polycrystalline diamond (PCD) is diamond powder polycrystalline products produced by sintering together selected synthetic diamond with a metal matrix using very sophisticated high-temperature and high-pressure technology. Polycrystalline diamond (PCD) widely used in natural diamond bruting,geological drill bits,oil well drill bits and other PCD dressing tools
