PDC bits uses PDC as main cutting components, with the excellent wear ability and impact toughness of the PDC. It has a long useful life, high efficiency, and good cost performance. PDC bit is mainly used ford rilling soft and big drainage. PDC is made of diamond micro-powder and hard tungsten carbide under high temperature and high pressure. It possess of high wear resistance like diamond, at the same time the impact resistance like tungsten carbide and that's made it the best material as a drill bit cutter. Reinforced PDC has higher dense diamond powder, claw tungsten carbide substrate made the two layers solid as whole one. So, the reinforced PDC of supper wear resistance, longer service life and high efficiency. Theory PDC (polycrystalline Diamond Compact) drill bit is a new product after the hot-pressed and electroplated drill bit in recent years. With special high-frequency welding techniques, PDC of high wear resistant is welded to the body as cutting edges. PDC bit is mainly used for geological prospecting coal exploration, water conservancy and power engineering, etc.

Structure features and applications of the bit:

1.Optimality designed bit profile suitable for drilling soft to medium formations and medium formations.

2.Cutting structure is force balanced and bit blade is asymmetrically designed so that the load on bit is balanced which resulting better stability of the bit.

3.Multiple types of high performance PDC cutters are strategically arranged on bit for improved service life of the bit.

4.Shock absorbers are designed to make the bit capable of drilling through formations with hard stringers.

5.Hydraulic system of the bit is optimized using dynamic flow pattern simulation technology to enhance cleaning and cooling effects of the bit to effectively prevent bit from balling.
