RRM (Roller Bearing-Rubber Sealing-Milled Tooth) bits is a kind of ideal and economic tool in high speed well drilling.

Product Features:

-Sealed roller bearing structure is placing the cylinder roller into groove of cone which increases the bearing neck size to load larger WOB and adapt high ROP.

-Surface of thrust bearing is hardening treated and wear reducing treated to improve the loading ability and anti-seizure ability of bearing.

-Optimized surface weld position and thickness of milled teeth to improve the wear resistance performance.

-Optimized milled teeth quantity and teeth arrangement structure give full play to the cutting ability and cutting speed of drill bits.
