This series have two kinds of classification: inserted bit and steel tooth.Inserted bit is inserted teethjet bit with sealed journal of oil bearing. Adopting the optimized design,the teeth placement of cone is reasonable, the tooth shape and height are designed differently in accordancewith various kinds of rock formations, and gage protection is better. The bear system which is adopted copperinlaid and silver plating improve the loading capacity and seizure resistance, and prolong the bit workinglife. This product is widely used for oil and natural gas field’s drilling and geological exploitation.Usingthis product, user can gain high drilling efficiency.Steel tooth bit is tri-cone bit with roller bearing foroil well drilling. The tooth surface is welded and applied with tungsten carbide powder coat. The bearingsystem is suitable for high rotary rate. Drilling in the adaptable rock formation,the bit can obtain high PRM,long working life, reliably working.All of the drilling bits are designed and manufactured strictly accordingto API-7-1 Spec Standard.
