(3)The PDC cutter features
1.long life-employing new sinter technics firms the bonding of diamond particles. The abrasion resistance has a vast increase, with 2-3mm of the diamond layer, this assure the diamond compact cutter has a longer life.
2.Higher impact resistance-The beveled interface of diamond layer and tungsten carbide, reduces reidual stress of PDC diamond compact cutter, and increase impact resistance.
Themal stability-the resist temperature reaches700°C,which makes reliable quality and better performance when PDC used in the drilling bits.
3.Nearly all of our PDC cutters are designed and manufactured to meet specific project requirements. They can be manufactured in many different shapes—from basic cylindrical cutters to inserts with customized angles, diamond thickness, chamfers, and sizes.
