PDC core bit,diamond PDC core bit
1. Circular arc brown, standard PDC cutters are distributed on the
blades.
2. Cutters distributed optimized with balance design so that the
stability and gain efficiency of drilling largely improved.
3. Column diamond is used in inner and outer gauge as protection,
besides that extra PDC cutters are used to enhance gauge
protection. Flow roomage is optimal designed so that bit can be
clean and cooled sufficiently.
4. This series of bits are suitable for medium to medium-hard
formation.
