Introduction
Polycrystalline Diamond Compact (PDC) bits are a type of drill bits used in the drilling industry. A PDC bit comprises a fixed head with several PDC cutters. Since the head is fixed and contains no moving parts, the bit rotates as one piece. PDC cutters or inserts consist of a layer of polycrystalline diamond and a tungsten carbide substrate. The polycrystalline diamond is bonded to the substrate. This advanced design allows for higher drilling efficiency and longer service life due to outstanding resistance to wear, abrasion, erosion, and high temperature.
PDC drill bits are widely used in various applications, such as welling drilling, mining, and oil and gas drilling.

Advantage of 17 1/2 inches PDC drill bit
Steel-body PDC bits offer superior impact resistance due to the strength and flexibility of steel. Compared to matrix bodies, steel bodies are much stronger. The use of steel allows for the creation of intricate bit designs and hydraulic configurations, which can be easily achieved using advanced milling technology. One of the key advantages of steel bits is their ability to be rebuilt multiple times by simply replacing worn or damaged cutters. This feature is especially beneficial for operators working in cost-effective drilling conditions.
