The advantage of rubber sealed tri-cone drill bit

Hard Alloy Welding Pervent bit wear and tear work and protect the bearing

Hard alloy drill palm surface neck protection prevent bit wear in abrasive formation

High stength tunsten carbide teeth ,high temperature hear treatment forged alloy steel

Lubricating system protection of the bearing and seal system of the bit

Sealed Journal bearing
