Precision PDC Cutter Characteristics
High consistency improves high speed rotation stability
Through the high-precision centerless grinding process, the cutter diameter and height tolerance are ensured to be controlled within ± 0.03mm. This high consistency ensures precise fit when the drill bit is arranged, reducing the small vibration caused by the installation gap, so that the stability of the drill bit at high speed rotation is improved by 40%.
Non-planar interface design improves impact resistance
The unique non-planar mesh interface design is used to increase the bonding area between the diamond layer and the cemented carbide substrate. After testing, its shear strength exceeds 3.5 GPa, which effectively solves the common problem of diamond layer delamination under high impact load, and its impact resistance is 25% higher than that of standard products.
Chamfer geometric design reduces the risk of tooth chipping
Provides a fluid-dynamics-optimized double or parabolic chamfer design. Compared with the traditional single chamfer, the cutting resistance of the precision pdc cutter is reduced by 15%, and it can cut into the rock more smoothly in the soft and hard staggered strata, reducing the risk of tooth chipping.
Thermal stability improvement of deep cobalt removal treatment
The diamond layer was deeply pickled and de-cobalt treated to remove the catalyst metal residue. This increases the thermal stability of the product from 700°C to more than 750°C, and the wear ratio can still be maintained above 400: 1 under extreme conditions of dry drilling or insufficient coolant.
Mirror polishing surface treatment to improve chip removal efficiency
The working faces of all precision pdc cutters were mirror polished with <0.1 μm Ra. The extremely low surface friction coefficient not only reduces the frictional heat generation during the drilling process, but also greatly reduces the probability of balling the drill bit, increasing the chip removal efficiency by about 20%.
high density diamond sintering
The mixed diamond powder with a particle size distribution of 2-30 μm was selected for ultra-high pressure sintering, and the volume content of diamond reached more than 92%. This high-density structure makes the product in the abrasive sandstone formation, the service life is 1.5 times longer than ordinary composite sheet.

Precision PDC Cutter Comparison Points
Compared with the common composite sheets on the market, our precision pdc cutter focuses on solving the pain points in difficult drilling. Ordinary products often due to large tolerances lead to uneven tooth stress, or due to poor thermal stability lead to premature failure, and we through strict quality control and advanced cobalt removal technology to solve the following problems:
Improve drill bit vibration and tooth distribution accuracy
For the pain point: the diameter error of low-precision composite sheet will lead to unstable interference fit, causing micro-vibration during drilling and accelerating bearing loss. Solution: Strictly implement the micron diameter tolerance standard of ± 0.03mm to ensure that each precision pdc cutter can perfectly match the drill hole, improve the dynamic balance performance of the drill bit, and make the drilling process more stable and smooth.
Eliminate the chain failure caused by “tooth collapse”
For pain points: in non-homogeneous hard rock drilling, ordinary cutting teeth often crack due to insufficient impact resistance. Solution: Through the optimized non-planar interface bonding technology, the impact stress is dispersed to the alloy matrix, so that the product can withstand the instantaneous impact of more than 450 Joules, and the tooth collapse rate in hard rock drilling is reduced by more than 60%.
Solve the thermal wear caused by high temperature in deep wells
For pain points: The high temperatures generated by deep well drilling can cause the cobalt catalyst to swell, causing the diamond layer to graphitize or crack. Solution: Using a deep decobalting process, the metal catalyst between the diamond grids is removed, so that the precision pdc cutter can still maintain the ultra-high hardness of diamond at a high temperature of 750°C, effectively resisting the wear caused by deep well geothermal heat and frictional heat.

Instructions for Precision PDC Cutter
Welding temperature strictly controlled
Operation suggestion: When brazing the precision pdc cutter to the bit body, the induction heating temperature must be strictly controlled. It is recommended that the welding temperature should not exceed 700°C – 720°C, and use an infrared thermometer to monitor in real time to avoid overheating causing micro-cracks or performance degradation of the diamond layer.
Storage environment and moisture-proof
Operational recommendations: The product should be stored in a dry, constant temperature (20°C-25°C) indoor environment with a relative humidity of less than 60%. Avoid direct exposure to humid air to prevent oxidation and rust of the cemented carbide substrate and affect the subsequent welding strength.
Handling and anti-collision protection
Operation suggestion: the diamond edge of the Precision pdc cutter is extremely hard but brittle. In the process of unpacking and handling, be sure to use plastic tweezers or wear gloves. It is strictly forbidden to directly impact the diamond surfaces of the two composite sheets to avoid microscopic chipping that is difficult to detect by the naked eye.
Surface cleaning before welding
Operation suggestion: Before the brazing operation, the surface of the alloy substrate should be thoroughly cleaned with anhydrous ethanol or acetone to remove oil and oxide layer. Ensure that the welding surface is clean and dry to ensure the wettability of the solder, so as to obtain the maximum strength of the shear bonding force.
