Size Range: 6" - 26"

The insert roller cone drill bit is suitable for drilling in medium - hard to hard formations. The cutting structure and sealing form of this drill bit can be designed in accordance with the formation lithology and drill bit model.

The insert drill bit uses high - quality cemented carbide with new formulas and processes, which can improve the comprehensive mechanical properties of the cutting teeth. The outer row of the roller cone is inlaid with trimming teeth, the back of the roller and the back of the tooth holder are inlaid with cemented carbide teeth, and the tip and front side of the tooth holder are surfaced - welded with wear - resistant alloy, enhancing the drill bit's gauge - protection ability. High - precision - fit sliding and rolling bearings, along with steel - ball locking, are adopted. The shaft diameter of the tooth holder is welded with wear - resistant alloy, and the inner hole of the roller cone is welded with special alloy and silver - plated, strengthening the wear resistance and anti - galling ability of the bearings and improving the bearings' adaptability to high - speed rotation.
