Introduction
PDC drill bit is mainly used to drill Oil well, gas well, water well, etc.We design and produce specifie PDC bit with good performance for each soft, medium and hard formation. Steel body with hardening tungsten carbide surface(WC),make the drill bit both high strength and very strong abrasion resistance. Low torque spiral design and software designed tooth reduce the cutting edge wear & increase life. The scientific drilling dynamic equilibrium design and hydraulic balance design make the drilling process more smooth.

Features
1.Durasef Gauge: Super strong material promotes gauge wear resistance to enhance long lifetime.
2.Hydraulics: The movement and cooling of cuttings can be optimized by the hydraulic design that matches the chip quantity and displacement of each blade.
3.Special Backrake Design: A Backrake can be added in the bit in order to prevent the bit from getting stuck when drilling.
