The roller drill bit has the function of impacting, crushing and shearing the formation rock when rotating, so the roller drill bit can adapt to various soft, medium and hard formations. According to the type of teeth, the roller drill bit can be divided into milling tooth (steel tooth) roller drill bit and insert tooth (carbide teeth are inserted on the roller) roller drill bit; according to the number of rollers, it can be divided into single roller, double roller, three roller and multi-roller roller drill bits.
Product Advantages:
1.Excellent sealing performance: rubber seals effectively prevent mud and particles from entering the bearing, reducing losses.
2.High wear resistance: the steel tooth design enhances wear resistance, is suitable for hard rock formations, and prolongs service life.
3.Good shock absorption performance: during drilling, it can effectively absorb vibration and improve operation stability.
4.Simple maintenance: compared with other sealing methods, rubber seals are easy to replace and maintain, reducing operating costs.
These characteristics make rubber sealed bearing steel tooth three-cone drill bits highly efficient and economical in various drilling environments.
