④Skirt Type
Retract Skirt
| Advantage | ・Retract wings help to guide the bit in and out of the hole →For drilling in broken or fissured rock where it is difficult to retract the drill string due to the hole collapse ・Less hole deviation |
|---|---|
| Disadvantage | ・Higher cost（vs Standard Skirt Bit） ・Decrease of flushing efficiency |
