5 1/2″(140mm) Reverse Circulation TCI Tricone Rock Bit with Central Jet Hole
1> Reverse Circulation is a special drilling process, the mud fluid is sucked from hole bottom to ground through central hole, rock chipes could be clear at higher rate than regular circulation.
2>This design of tricone bits has a central jet hole , rock chips could be circulated to ground inside drill pipe.
3>Reverse circulation is always used in drilling pebbles or sparse rocks, the ROP is higher than normal circulation.
4>The tricone rock bit with central hole could be used in both reverse circulation and normal circulation.
