Rock bit classifications
- IADC prepared a comparison chart, in 1972
- Each bit is design by three code system
- First code classifies the cutting structure, 1-3 for teeth soft, medium and hard, 5-8 for insert, soft medium hard semi abrasive, extremely hard and abrasive, 4 for future
- Soft rock require long, slim and widely spaced teeth
- Medium requires short and less widely teeth
-Hard requires very short and closely spaced teeth
- Code 2 relates to formation hardness with division from 1 to 4 from softest to hardest
- Code 3 for mechanical features of the bit, sealed non-sealed etc
- Each company give there tables with IADC specifications
