Core Bit

HQ impregnated diamond core drill bit is special designed to drill high quality core bits. It's structure is very strong, and it is evenly distributed with diamond particles. This design makes the bit extremely durable and powerful, allowing it to easily drill through a variety of rock layers.

Type:
Surface Set Impregnated Diamond Core Drill Bit:

Surface set impregnated diamond core drill bits feature a single layer of diamond particles embedded on the outer surface of the bit matrix.
These bits are well-suited for drilling in soft to medium-hard formations, providing fast penetration rates and good core recovery.

Matrix Impregnated Diamond Core Drill Bit:
Matrix impregnated diamond core drill bits have diamond particles distributed uniformly throughout the entire matrix of the bit.
This type of bit offers improved durability and wear resistance, making it suitable for drilling in harder formations and abrasive conditions.

Structure:

Single Tube Impregnated Diamond Core Drill Bit:
Single tube impregnated diamond core drill bits consist of a single tube design where the diamonds are embedded directly into the bit matrix.
These bits are lightweight and efficient, making them ideal for shallow to medium-depth drilling applications.

Double Tube Impregnated Diamond Core Drill Bit:
Double tube impregnated diamond core drill bit feature an inner and outer tube design, with the diamonds embedded in the outer tube.
The double tube configuration provides added protection to the core sample, especially in unstable or broken formations, and allows for the use of larger diameter core barrels.
