Tungsten carbide roller cone bits for use at home and abroad, mostly three-cone drill. This drill is characterized by: axial compression and impact a larger range and uniform load distribution, and can make full use of available space, into stable. The size and shape of the cone bit with carbide teeth must be applied to properties of rocks, requiring good wear resistance, high strength, not broken, and broken. Carbide tooth roller cone bits used are: spherical gear, bevel gear ball, wedge-shaped teeth, tooth edge wedge teeth and topped with Zhao Jian, such as for the back wheel.
