B N H P Wireline Natural Diamond Surface Set Core Drilling Bits 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.
| Diamond Size | Formation Drilled |
| 10/20 SPC* | Soft formation |
| 20/30 SPC | soft to medium formation |
| 30/40 SPC | medium formation |
| 40/60 SPC | Medium to hard formation |
| < 60/80 SPC | Very hard formation |
| *SPC is short for Stone per Carat **40/60 is Forsun standard diamond size for natural diamond core bit ***Other sizes are available as per request | |
