138mm roller cone bit is made by tungsten carbide inserts are full fitting on surface ,it is different from traditional Single cone roller bit that inserts are groove-inserts-groove design.

Steel material of arm and cone is important for the quality, we use 15MnNi4Mo steel for cone, and we use 15CrNiMo steel for arm, it is standard steel material for oil well drilling tricone bit.

Among cone-diameter 133mm roller cone bit in Solidkey, this model is almost the best quality and performance, we have many regular customers from China domestic and South-East Asia,  many deep piling holes are requested in foundation projects for tall building and railway construction.
