This Diamond PDC Drill Bit adopts high-quality polycrystalline diamond composite sheet and reinforced matrix design, greatly improves the rate of penetration (ROP) by optimizing the cutting structure, and shows excellent wear resistance and long life in hard rock and abrasive formations. It is an ideal choice to reduce comprehensive drilling costs and can be ordered in batches.

premium-grade polycrystalline diamond compact is used to continuously produce new cutting edges during wear. This self-sharpening feature ensures that the rate of penetration fluctuates by less than 15% in long-distance drilling, eliminating the need for frequent tripping and bit changes.
The matrix is sintered from tungsten carbide powder, and the hardness is as high as HRA 88-92. Compared with the ordinary steel drill bit, its erosion resistance is improved by more than 3 times, and it is especially suitable for the complex formation environment with high sand content and strong abrasiveness.
5-7 replaceable nozzles are configured, and the flow channel design is calculated by CFD. This structure can ensure that the mud can cover the cutting edge by 100, effectively prevent the phenomenon of “mud-packed bit”, and improve the removal efficiency of bottom-hole cuttings.
non-planar interface bonding technology is used between the composite sheet and the substrate to increase the impact toughness by 40%. Even when encountering interlayer or soft and hard alternating strata, it can effectively reduce the risk of chipping caused by vibration.
Through a special lateral gauge design, the gauge block is inlaid with natural diamond particles. This not only ensures that the hole diameter deviation after hole forming is controlled within 0.1mm, but also reduces the lateral vibration of the BHA.
provide a variety of options from 3 blades to 8 blades. For soft formations, the 3-4 blade design of large flow channels can increase the chip removal space by more than 50%. For extremely hard formations, the multi-blade layout can share the cutting load.

suitable for continuous drilling of deep and ultra-deep wells. The high durability of PDC bits can significantly reduce the number of trips in deep well operations, saving contractors tens of thousands of dollars in non-productive time (NPT) costs.
for geothermal drilling in the common granite and other high hardness, high temperature formation. This product can withstand the underground high temperature environment, and the cutting efficiency is much higher than the traditional cone bit.
in the general survey and detailed investigation stage of gold, copper and other metal deposits, the use of diamond PDC bits can obtain a more complete core extraction environment and speed up the overall construction progress of porous operations.
to meet the drilling needs of large-diameter wells and bridge pile foundations. In soft to medium hard formations, its extremely high ROTPED can assist the team to complete standardized hole-forming operations in a shorter time frame.
The core cutting element of this product is made of top polycrystalline diamond powder (Micron Diamond Powder) and cemented carbide substrate (WC-Co) sintered under ultra-high pressure and high temperature. Carcass part of the selection of high quality tungsten carbide powder as the skeleton material, supplemented by nickel, manganese and other impregnated alloy. The steel body model is made of AISI 4145H alloy steel, which has been precision heat treated to obtain extremely high structural strength.
Our factory
A: The matrix bit has strong erosion resistance and is suitable for high abrasive and strong corrosive formations; the steel body bit has larger cutting space and better mechanical strength, and is suitable for fast drilling of high speed, soft to medium hard formations.
A: Usually caused by severe axial or lateral vibration, especially when heterogeneous formations are encountered or when operating parameters (such as high speed) are not met. Our impact-resistant interface design effectively reduces such risks.
A: Yes. However, it is necessary to choose a smaller diameter (such as 13mm) cutting teeth and a denser blade layout to increase the cutting density per unit area.
A: When the rate of penetration (ROP) drops more than 50% under the same parameters, or the torque fluctuates abnormally and cannot be recovered by adjusting the WOB, the trip inspection should be considered.
A: The nozzle determines the water horsepower (HSI) at the bottom of the well. Smaller nozzles produce a stronger impact force to help clean up the viscous formation; larger nozzles provide a greater flow rate to cool the heat in the hard formation.
A: Yes. As long as the carcass or steel body matrix is not seriously damaged, the worn PDC composite sheet can be removed and replaced with a new sheet through a professional heating process, thereby extending the overall life of the drill bit.

Optimized for HE (high efficiency) and septic systems. The low-foam formula can prevent the foam layer from being too thick to interfere with the solid settlement process in the septic tank, ensure the effective separation of solids, liquids and scum in the wastewater, and improve the treatment efficiency of the system.
