The advantage of tricone rock 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
You can find the bit Diameter,thread Pin IADC code Serial number on the bottom
