Product Introduction
Rotary drilling uses two types of drill bits: roller-cone bits and fixed-cutter bits. Roller-cone bits are generally used to drill a wide variety of formations, from very soft to very hard. Milled-tooth (or steel-tooth) bits are typically used for drilling relatively soft formations. Tungsten carbide inserts bits (TCI or button bits) are used in a wider range of formations, including the hardest and most abrasive drilling applications.

Product Features
1.This series adopts non-isometry teech placement in combination with optimized teeth height and shape.
2.Applying the world's latest sealing technology-metal face sealing ensures the bearing sealing is more efficient,and more suitable for drilling at high rotary speed and high temperature working condition.
3.New material is applied on the part of gage protecting, and reducing the friction from oil-well-wall ,improving quality of well wall,protecting the back of leg and seal.
4.Bit's bear is enhanced treatment,and prolonging the bit working life,reducing the drilling cost.
