Application
1. The6 1/4” IADC 517 blast hole bits are designed for drilling soft to medium hard formations, with rock compressive strength ranging from 10,000 to 35,000 psi.
2. Formation drilled may consist of shale, limestone, quartzite, slate, sandstone and granite.
Specifications
| IADC code | Applicable Formation | Main characteristics of the bit | Recommended parameters | |
| Cutting structure | Normal WOB kN/mm (bit dia.) | Rotary speed (rpm) | ||
| 517 | Soft formations with low compressive strength and high drillability, such as shale, clay, rock salt, soft limestone, etc. | Large radius scoop compacts in inner row, wedge compacts in outer row, inequable spaced compacts arrangement , and a row of trimmers is added between gage row and heel row | 0.50~1.05 | 220~40 |
