Far Eastern have designed roller bit with foundation, it can replaceable the roller bit, in this case, you will not worry welding on the rock reamers. Because welding the roller bit on the rock reamers is a high technology, to control the temperature. Our roller bit also fit for all sorts of rock formation. High precision bearing surface heat treatment adopts advanced heat treatment technology to improve the bearing capacity and service life. The roller bit has metal sealed bearing and rubber sealed bearing. The Advantage of Roller Bit: The cone units of Far Eastern Roller Cone Cutters are replaceable and each main body of the Hole Openers can be used many times, thus saving the cost for the customer. The strength and wear resistance of inserts is improved by using carbide inserts with high strength and high wear resistance. For steel tooth drills, the tooth surface is hard and has new wear resistance. The material thus extends the life of the cutting structure while still maintaining a high ROP. Features of C142 series
