API 9 3/4" Drilling Bit, 248mm PDC Bit, 6 Blades
The PDC bit utilizes the mechanical properties of rock, using an efficient shearing method to break the rock. This achieves faster drilling compared to traditional crushing methods. In soft to intermediate formations, the compact cutting teeth overcome formation stress, sliding forward under weight-on-bit (WOB) and torque to produce large cuttings efficiently transported by mud jetting.

A1: The PDC bit uses a shearing mechanism rather than crushing. Since rock tensile and shear strengths are much lower than compressive strength, shearing is a more efficient way to break rock, leading to faster drilling speeds.
A2: The drill body is manufactured from high-grade 42CrMo alloy steel, while the cutting elements are made of Polycrystalline Diamond Compact (PDC) for maximum wear resistance.
A3: This 6-blade PDC bit is ideally designed for formations with soft to intermediate hardness, where its shearing action can be fully utilized.
A4: It features a standard 6-5/8" API REG connector, ensuring compatibility with standard oil well drilling strings.
A5: The bits are packed in durable iron boxes to prevent any physical damage during transport, with a gross package weight of approximately 160kg for this specific model.
A6: Yes, the production process is certified under ISO 9001:2000 and has been inspected by SGS to ensure global quality compliance.
