1. Unique design parameters and a wider blade top extend rock break and increase bottom hole coverage. At the same time, the shear sliding distance of the bottom hole blade is increased, and the ROP of the hard and plastic formation bit is increased.
2. The convex wedge has the characteristics of strong effective cutting ability and fracture resistance, which can effectively increase ROP and improve the service life of the bit. It is suitable for the following strata with moderate soft to moderate hardness.
3. The main tool of the drill is conical spherical pressure block, which is suitable for drilling in hard and brittle strata.
The company is located in Junziguan Village, Shijing Township, the ancient town of civilization, 156+8 kilometers away from the 106 National Road, with convenient and smooth transportation.
