IADC Digital Coding Regulation
1st digit = Cutting type
1~3: Milled tooth
4~8: TCI
2nd digit = Drilling formation
1~4 : Soft ~ very hard
3rd digit = Bearing type
1: open roller bearing / non sealed roller bearing
2: air cooled roller bearing / non sealed air cooled roller bearing
3: non sealed roller bearing with gauge protection
4: sealed roller bearing
5: sealed roller bearing with gauge protection
