Product introduction:
1, Tungsten carbide matrix body
2, 19mm PDC cutters.
3, parabolic crown profile
4, PDC in gage
5, medium density cutters with 4 (to9)blades of spire, deep and wide junk slot.
6, uitable for medium soft to medium formations.
7, anti-whirl design
The drill bit adopts short parabolic profile optimization, suitable for soft to medium soft formation.
Gradually open the asymmetric spiral blade teeth arrangement design. Improve the stability of the bits.
The main and auxiliary cutting structure design, improve the life
Design and Simulation of hydraulic balance of bottomhole flow field, more conducive to the drill bit cooling cleaning and chip
Composite gage low torque design, improve the drilling efficiency
High performance composite sheet used in combination, improve the service life of the drill bit
