How PDC Cutters are made

About PDC (Polycrystalline Diamond Compact) Cutter

PDC (Polycrystalline Diamond Compact) Cutter is kind of superhard material that compact polycrystalline diamond with tungsten carbide substrate at ultra-high temperature and pressure.

How PDC Cutters are made

PDC Cutters are made from tungsten carbide substrate and synthetic diamond grit. It is made using a combination of high temperature and high pressure with catalyst of cobalt alloy to help bond diamond and carbide during the sintering process. During the cooling process, the tungsten carbide shrinks at a rate of 2.5 times faster than the diamond, which combines Diamond and Tungsten Carbide together and thereafter forms a PDC Cutter.

Characteristics of PDC Cutters 
Since PDC Cutters consist of diamond grit and tungsten carbide substrate, it combines advantages of both diamond and tungsten carbide and featured high abrasion resistant, high impact resistant and high thermal stable.

History and Demand of PDC Cutters
PDC Cutter was invented firstly by General Electric (GE) in 1971 and this technology has driven many industries to new revolution. First PDC Cutters for oil and gas industry was done in 1973 and with 3 years of experimental and field testing, it is introduced commercially in 1976 after it is proven much more efficient than crushing actions of button bits.

More and more innovation happened to PDC Cutters for oil and gas drilling due to expanding market request. In 1982, PDC drill bits done only 2% of total footage drilled, but in 2010, 65% of total footage drilled was done by PDC drill bits.
