tungsten carbide insert tooth powerful brand quality in China
1) TCI tricone drill bit size 3 inch 26 inch， IADC 517/537/617/637 is suitable for soil, mudstone, gypsum, rock salt, chalk, soft lime，soft shale，with hard interlayer below 40 MPa Soft formation.
2) TCI tricone drill bit Bearing : rubber seal， compound seal， metal seal. The bearing seal structure can be selected from rubber seal, composite seal and metal seal bearing. The service life of the bearing is different. For different working conditions， the product can be reasonably matched with the working conditions， the product can be reasonably matched with the customer to effectively control the cost of drilling
