8 1/2FM13065IU PDC drill bit
Medium to medium hard formation drilling
Products with optimized profile is suitable for drilling medium to medium hard homogeneous formations with low abrasiveness.
Cutting structure
Asymmetrical evolute blade cutters placement prevents the bit whirl. Primary and secondary cutting structure design increases impact strength of the bit.
Hydraulic system
CFD hydraulic balance design results in better bit cleaning and cutting removal.
