PDC core bits incorporating PDC(Polycrystalline Diamond Compact) cutters can be very cost effective and very productive, which are applied to rock formations of f≤10,mainly used for geological and hydrology drilling.
We have two main types of PDC core bits are available: PDC rib core bits and PDC flat core bit.
The PDC rib core bits are applied to rock formation of f≤6, like mudstone, sandstone, etc.
And the PDC flat core bits are applied to rock formations of f≤10,like limestone, granite, etc.
