Quick details of 76mm drill bit
All thread bits are available in various flushing hole configuration. In general, the rule is that:
1. Semi-spherical type bit design are applied to very hard rock
2. Ballistic type to medium hard
3. Conical type to soft rocks.
Bit design | Brief Introduction |
Drop center |
Perfect in abrasive formations where there is accelerated button wear or in medium to hard rock when ballistic buttons have tendency to break.
|
Drop center/retrac |
To be used in medium-hard and fissured rock formations, better hole deviation control.
