6 Blade PDC Drill Bits Characteristics
Balance The Lateral Force When The Drill Bit Rotates
Through the precise calculation of the 6-blade symmetrical layout, effectively balance the lateral force when the drill bit rotates. Compared with 4-blade or 5-blade drill bits, the vibration under high-speed rotation is reduced by 25%, ensuring the straightness of the borehole trajectory.
Impact Resistance Performance Improvement
The selection of excellent thermal stability of the 1308/1608/1908 specifications of the composite sheet, diamond layer thickness of more than 2.0mm. In abrasive formations, its impact resistance is 40% higher than that of ordinary composite sheets, significantly extending the life of cutting teeth.
Reduce The Number Of Tripping
The gauge part is inlaid with high-density hard alloy cylindrical teeth or diamond reinforcement blocks, and the gauge tolerance is strictly controlled within +0.1mm. This effectively prevents the problem of diameter reduction caused by wear in deep hole operation and reduces the number of tripping.
High-efficiency Nozzles Prevent The Drill Bit From “mud”
3-6 replaceable tungsten carbide nozzles are configured, and the optimized chip groove (Junk Slot) depth ensures large displacement flushing. This design can quickly carry away the debris, prevent the drill bit from “mud”, and improve the chip removal efficiency by 20% in the viscous formation.
Resistance To High-flow Mud Erosion
The surface of the steel type 6 blade PDC drill bits is coated with laser surfacing tungsten carbide, with a hardness of 60-65 HRC. This protective layer can resist the erosion of high velocity mud and reduce the erosion rate of the substrate by more than 50%.
Superior Sealing And Fracture Resistance Of The Joint
The threaded interface strictly implements API Spec 7-1 standard and is precision machined by CNC machine tools to ensure high torsional connection with the drilling tool assembly (BHA). Excellent joint sealing and fracture resistance under extreme torque loads.

Mining and Ventilation Hole Construction Manager
In large-diameter anti-shaft drilling or ventilation hole construction in mines, the drill shows excellent wear resistance, can cope with complex ore layers, reduce downtime losses caused by bit replacement, and improve comprehensive mining efficiency.
Director of Trenchless HDD Crossing Project
In the horizontal directional drilling construction of urban pipe network laying and river crossing, 6 blade PDC drill bits can be adapted to various guiding tools to ensure that the direction can still be controlled accurately and rock can be broken efficiently in complex geological environment.
6 Blade PDC Drill Bits Lifetime and After Sales Service
Product life expectancy and instructions for use:
Under normal conditions, the cumulative footage of a single 6 blade PDC drill bits can reach 300-800 meters (depending on the formation hardness and abrasiveness). During use, the recommended curve of weight on bit (WOB) and rotation speed (RPM) shall be strictly observed. It is strictly forbidden to drill into the hole with falling objects at the bottom. It is recommended to check whether the nozzle is blocked every 100 meters.
Pre-sales and after-sales service:
Provide professional geological selection guidance before sales, and customize the composite sheet arrangement according to the formation hardness (drillability level). After-sales commitment to respond to technical advice within 24 hours, to provide paid renovation and cutting tooth replacement services for steel drill bits, and to provide quality assurance for all manufacturing defects.
6 Blade PDC Drill Bits Raw Materials/Materials
The core cutting element of this product adopts high-end industrial grade PDC (polycrystalline diamond compact), and the purity of diamond powder is more than 99.9%. The drill matrix is made of high-strength AISI 4145H alloy steel (steel body) or matrix material made of high-content tungsten carbide powder through vacuum sintering to ensure extremely high structural strength and wear resistance in the downhole environment of high temperature, high pressure and strong corrosion.

Our factory
Q1: Are 6 blade PDC drill bits suitable for use in granite formations?
A: Not recommended. The product is optimized for use in soft to medium hard formations. For extremely hard or abrasive formations such as granite, a higher blade count (e. g., 8 blades) or roller cone bits are recommended.
Q2: Matrix and steel body 6 blade bit how to choose?
A: The matrix bit has strong erosion resistance and is suitable for high corrosive environment and long deep well operation. The steel body bit has good impact resistance and high repairability, and is suitable for shallow hole operation with large changes in formation properties.
Q3: How do I make sure that the drill bit is connected to my drill pipe?
A: Our 6 blade PDC drill bits are all API compliant connections. Common specifications such as 6 “drill bits are usually equipped with 3-1/2” API Reg threads. You only need to inform the diameter of the drill bit and we will match the corresponding joints.
Q4: Why is a 6-blade drill more stable than a 5-blade drill?
A: 6 blades provide more contact points (Point of Contact), can more evenly distribute the cutting load, effectively suppress the eddy current effect, thereby reducing the lateral vibration of the drilling tool.
Q5: What should I do if there is mud wrapping in PDC bit?
A: Please check the mud displacement and nozzle angle. Our 6-blade design has a spacious flow channel, which can usually solve the problem of slight mud packing by increasing the displacement of the mud pump.
Q6: Can the composite sheet be replaced separately after wear?
A: For steel type 6 blade PDC drill bits, new composite pieces can be removed and welded by professional induction heating equipment. It is usually not recommended to replace the tyre type drill bit to avoid damaging the matrix.
