PCD NQ HQ PQ Polycrystalline Compact Diamond PDC Diamond Drill Bits


The PDC bit is short for polycrystalline compact diamond bits. It is made up of tough, anti-friction matrix and gauge reinforcement. The PDC coring bit is suitable in homogeneous soft to medium sedimentary forms.      



1. There are several sizes of PDC cutters with high productivity and long service life.

2. Wearing cutters can be replaced to be utilized again.

3. PDC coring bits are of all standard drilling sizes and many region-specific sizes.

PDC Drill Bit

This PDC drill bit is a fixed pattern with a designed type of matrix on the top and equipped with natural diamonds on both sides. There are two types of the PDC drill bits: coring and non-coring drill bits. They are used to drill coal, gas and oil in soft to medium hard forms. The PDC drill bits consist of: 28mm, 32mm, 42mm, 45mm, 48mm, 56mm, 65mm, 76mm, 85mm, 96mm, 99mm, 114mm, and 123mm. The thread is NW male thread. Samples are available.


PDC Coring Bit

It is applied in coal exploration from soft to medium hard forms. The PDC coring bits include: AQ, BQ, BQ3, NQ, NQ3, NQTT, HQ, HQ3, HQTT, PQ, PQ3, and PQTT.


PDC Drill Bit

This PDC drill bit is also used in coal exploration from soft to medium forms as a base drilling. The PDC coring bits contain HWF, 412, PWF, SWF, NQ3, HQ3, NQTT, HQTT, PQ3, and PQTT of the face discharged.
