PDC-(polycrystalline Diamond Compact） is a kind of composite superhard material sintered under ultra-high pressure and high temperature by using Diamond powder and hard alloy substrate as raw material. It not only has the hardness and wear resistance of Diamond, but also has the strength and impact toughness of hard alloy. It is an excellent cutting tool and wear resistant tool material, and is now widely used in metal and non-metal cutting tools, wood processing tools, oil and gas drill bits and many other fields.
In geological drilling, coal drilling and oil and gas drilling, polycrystalline diamond composite bit (PDC) has become one of the most commonly used rock breaking tools because of its excellent cutting speed and long service life.
Advantages of PDC drill bit:
1. Reasonable arrangement of different patented PDC drill bits in different positions of the bit makes the bit have strong aggressiveness and abrasiveness.
2. Strong aggressive design can make the drill bit to obtain a higher rate of penetration.
3. The drilling ability in rock formation is 10-30 times that of ordinary alloy bit, improving the operation efficiency.
4. Because the material of PDC drill bit is mainly cast tungsten carbide and diamond composite sheet, so it has long life and high value.
