Application:
PDC coring bits use GK PDC as cutting teeth,with excellent wear ability and impact toughness, they have useful life andgreat efficiency, especially suit for cobblestone, conglomerate andmoorstone,crumbly and loose formation.
Characteristics:
high wear resistance and impact resistant, longdrilling life, drilling efficiency can be promoted sharply in penetration ofsoft medium and medium-hard formation, laber intensity can bereduced.
Product Advantages:
1. PDC cutters for high speeddrilling;
2. All cutters are premium grade for extendedbit life and durability;
3. Cutter layout is force balanced to drill aprecise round hole and reduce bit whirl;
4. Large junk slots and flushingports;
5. Advanced geometric design for fasterpenetration;
6. Gauge pads have tungsten carbide inserts formaximum wear resistance
