12inch steel tooth drill bit

1) Steel tooth roller bit, size 6 inch-121 / 4 inch, IADC 117/127/217 is suitable for soil, mudstone, gypsum, rock salt, chalk, soft lime, soft shale, with hard interlayer below 40 MPa Soft formation. 2） 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 customer to effectively control the cost of drilling
