YHA 8 1/2“ 417/437/517/537
 |
High wear resistance and excellent cutting ability of the insert bit are given full play by using carbide combination with optimized compact numbers and rows,the exposure height and special shaped compacts. |
 |
For YHA,a row of inserts is added between gage row and heel row to trim borehole wall and protect cone shell. |
 |
Leg and Shirttail protection: Leg are protected by hardfacing and tungten carbide inserts ,For highly abrasive formations diamond coated tungsten carbide inserts can be used . |
| ALL rubber compensator is used which can limit pressure differential and prevent drilling fluid from entering the lubricationsystem and this provides the bearing system with good assurance of lubrication. |  |
