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.Good sealing: rubber seal prevents oil leakage and impurities from entering, extending the life of the drill bit.
2.High temperature and wear resistance: adapt to high temperature and high pressure environment.
3.Long-lasting lubrication: effectively maintain internal lubrication and improve work efficiency.
4.Strong cutting force of insert teeth: suitable for hard formations and improve drilling speed.
5.Strong impact resistance: three-cone wheel design withstands greater impact and works stably.
6.Simple structure and easy maintenance: low maintenance cost and long service life
