PDC core drill bit 

Characteristics: high wear resistance and impact-resistant toughness, long drilling life, drilling efficiency can be promoted sharply in penetration of soft medium and medium-hard formation, laber intensity can be reduced.

 

Introduce of PDC

This kind of PDC is sintered at high pressure and temperature, which is composed of diamond and kentanium. It can be embedded into mine drill that used in medium-high hardness stratum drilling. 

The special shape and diffe banrent technique make this PDC higher drilling speed, and especially suitable for siliceous rock, conglomerate.

 

Application: This group of products is used to coring-drilling for geological exploratory of coal measure stratum.

 

Product Advantages:

1. PDC cutters for high speed drilling;

2. All cutters are premium grade for extended bit life and durability;

3. Cutter layout is force balanced to drill a precise round hole and reduce bit whirl;

4. Large junk slots and flushing ports;

5. Advanced geometric design for faster penetration;

6. Gauge pads have tungsten carbide inserts for maximum wear resistance;
