Drill bit Characteristics & Applications
1. Drill bit contour optimize the design, adapt to the in the soft to medium strata.
. 2. Cutting structure force balanced by the Design of OF, the wing in in non-Symmetric knife Design of, enable the DRILL affected by the force balanced by the, having a the better of the Stability of.
3. The main cutting tooth using high-performance a composite sheet, in the to ensure that of the at the same time of the life of the bit, improve the mechanical drilling speed.
4. The optimization of the composite sheet toothy high, the to so that a drill to has a high mechanical the speed of drilling in the the in the strata of the soft to medium.
5. Deep chip removal groove design, improve the the drill bit chip removal the ability to, so as to achieve the the the The purpose of of the improve the mechanical drilling speed.
6. The use of the dynamic flow field simulation technology, to optimize the the drill bit the hydraulic design of, and enhance the drill bit cleaning, cooling ability and prevent drill bit to the mud pack.
7. Long Bao-diameter design, drill bits has a the better of steady oblique the ability to.
