Products Description LEANOMS
Diamond Core Bit Hard Rock is widely used in exploration, mineral exploration, geological drilling and other fields. It can efficiently cut hard rocks, ensure high-quality core sample collection, and provide important data support for geological research and exploration projects.
Such Diamond Core Bit Hard Rock usually uses different designs and diamond grain configurations based on different geological conditions and rock hardness. Selecting the appropriate diamond core drill bit is one of the key factors in ensuring efficient and smooth drilling operations.
How to choose LEANOMS
Hard rock (such as granite, gneiss):
Choose a drill bit with high grit and hard diamond.
Consider using a larger size diamond core drill bit to increase penetration efficiency in hard rock.
Medium hard rock (such as limestone, shale)
Choose a diamond core drill bit with medium grit and hardness.
Consider using a moderately sized drill bit that balances drilling speed and cut quality.
Soft rock and loose formations (such as mudstone, and sandstone):
Select softer and larger grain diamonds to improve cutting performance in loose formations.
Consider using smaller size diamond core drill bits to reduce debris generation in unconsolidated formations.
Multi-layered rock formations:
Consider using a diamond core drill bit with a multi-level cutting design to accommodate rock with different hardness levels.
Hard inserts such as cement and steel bars:
Choose a diamond core drill bit that is wear-resistant and tough to handle the hard inserts you may encounter.
Product structure LEANOMS
The structure of Diamond Core Bit Hard Rock mainly includes the following components:
Bit Body: The drill bit steel body is the main structure of the entire drill bit and is usually made of high-strength alloy steel or other wear-resistant materials. It withstands the pressure and impact during the entire drilling process.
Thread Connection: The connecting thread of the drill bit is used to connect the drill bit to the drill pipe to ensure a stable and reliable connection to transmit torque and rotational power.
Carbide Step: The circlip seat step on the drill bit is usually made of carbide (tungsten carbide, etc.) and is used to enhance the wear resistance and cutting ability of the drill bit.
Drill bit water inlet (Waterways): The drill bit water inlet is a channel system used for cooling and flushing to ensure a good cooling effect during the drilling process and prevent the drill bit from overheating.
Internal and external gauge polycrystalline (Matrix): The matrix of the drill bit is composed of agglomerated diamond particles and can be divided into inner and outer layers. This structure can provide better cutting performance and wear resistance, and can adapt to rocks of different hardness.
Drill bit lip surface (Lip Surface): The drill bit lip surface is the part in direct contact with the rock. It usually includes diamond sheets or diamond particles and is used for cutting rocks.
Drill bit matrix (Matrix Body): The drill bit matrix is a matrix made of a mixture of diamond matrix and metal powder. This structure enables the drill bit to better disperse and transmit impact force when cutting rock, improving its durability.
The Diamond Core Bit Hard Rock structure is designed to overcome the high hardness and wear resistance of hard rock to ensure efficient core drilling in a variety of geological conditions.
