GF6645
The advanced simulation technology enables the bit more stable in drilling. It can drill interbed formation without serious broken and wear as conventional PDC design.
Parameter of GF6645
Soft To Medium-hard Formation Application
5 Blades, suitable for drilling in soft to medium-hard formation.
Anti-whirl Technology
The advanced simulation technology enables the bit more stable in drilling. It can drill interbed formation without serious broken and wear as conventional PDC design.
Tapered Blade
Strengthened blade and lengthened junk slots can get high ROP in soft formations and better cooling the bit in the hard and abrasive formations.
