(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.

Hejian Wanda Petroleum Machinery Co.,Ltd. Supplies all kinds of PDC coring and non-coring bits, PDC sintering matrix bits and PDC anchoring bit. We also can design PDC bits according to customer requirements, such as different geology condition, special strata and so on.
