B N H P Wireline Natural Diamond Surface Set  Core Bit For broken formation rocks 

Surface Set Diamond Core Bits:

Set with singular layer of natural/synthetic diamond and utilized a hard matrix compound on the bit face, our surface set diamonds can help ensure sufficient overlap to prevent premature wear of the matrix. This diamond tool is also suitable for drilling broken formation rocks which cannot be cored.

Standard Profiles for Surface Set Core bits:

Multi-steps

Semi-round

Face discharge(FD)

Non-coring bits with concave profile

To choose a right surface set for the formations drilled, we need at least consider the following aspects: diamond size, diamond grade, profile design.
