oil /waterwell mining/coal mining 8 1/2 " PDC bits
Product Description
bit specification
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
High performance composite sheet used in combination, improve the service life of the drill bit
Design and Simulation of hydraulic balance of bottomhole flow field, more conducive to the drill bit cooling cleaning and chip
