Product Overview

The IADC S323 4-5/8 inch PDC Drill Bit is a high-efficiency fixed-cutter drilling tool strictly designed and manufactured in accordance with IADC standard classification codes, specially optimized for medium-soft to medium-hard homogeneous formations widely encountered in oil, gas, water well and geothermal drilling projects. Classified as S323 by IADC, this bit features a steel body structure, medium aggressive cutting profile, and standard nozzle configuration, making it the most versatile and cost-effective model in the mainstream small-size PDC Bit series. With a precise diameter of 4-5/8 inches (117.475mm), it perfectly matches the drilling requirements of slim-hole wells, workover wells and small-caliber exploration wells, solving the problems of low efficiency and poor adaptability of traditional roller bits in soft and plastic formations.
This PDC Drill Bit adopts high-strength integral alloy steel body formed by overall forging and precision machining, with high structural rigidity and impact resistance, effectively avoiding body deformation and blade breakage during high-speed rotary drilling. The cutting structure is equipped with high-quality polycrystalline diamond compact cutters with high wear resistance and thermal stability. The optimized cutter layout, back rake angle and side rake angle greatly enhance the rock-breaking ability, achieving shear-type rock breaking instead of extrusion breaking, which significantly improves drilling speed and reduces unit drilling cost. The rational junk slot design ensures smooth discharge of rock cuttings, prevents bit balling and mud包堆积, and guarantees continuous and stable drilling operation. Equipped with standard high-efficiency nozzles, the bit realizes powerful hydraulic cleaning and cooling, effectively reducing cutter temperature and prolonging the service life of cutting teeth.
Applicable to typical formations such as clay, mudstone, shale, soft limestone and weathered sandstone, the IADC S323 4-5/8" PDC drill bit maintains stable drilling performance under conventional weight on bit and rotary speed parameters. Compared with conventional Tricone Bits, it has the advantages of higher ROP (rate of penetration), longer service life, lower vibration and simpler bottomhole assembly. All products undergo strict quality inspection including dimensional calibration, cutter welding strength test and hydraulic performance detection before delivery, fully complying with IADC and API industry standards, and can adapt to various conventional and mild complex drilling working conditions, providing reliable and high-efficiency drilling solutions for global Drilling Engineering projects.
