1). Uses outline optimization design, adapts in different strata.
2). Short parabolic crown, cutting force balance design structure, spiral knife- wing, balance the bit force, improve impact resistance.
3). Uses the dynamic flow field technique of simulation, optimizes the drill bit water power design, strengthens the drill bit clean, cooling capacity and prevents the drill bit balling.
4). Using high performance compound piece combination , enhances the bit life.
5). We have got the passport into the Russianmarket.
