1>NG2 has two types, one is 49 pcs of carbide teeth(outside height of teeth is 7.7mm), another is 56 pcs of carbide teeth(outside height of teeth is 9mm).
NG2-49/7.7 has better performance in drilling extremely hard rocks, NG2-56/9 has higher penetration rate in medium hard and hard rocks.
2>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.
3>The bearing is sealed, grease is injected by vacuum machine.
