Drillstar PDC hole opener is a reliable solution for borehole enlargement in sections where PDC cutting structures offer a performance advantage over roller cone cutting structures.
Drillstar PDC hole opener is a reliable solution for borehole enlargement in sections where PDC bits offer a performance advantage over rock bits.
The body is machined out of a single block of heat treated AISI 4145H alloy steel. The unique design of the body ensures maximum strength and durability. It can withstand loads far beyond those involved during normal drilling operations.
During drilling, load is transferred directly from the arms to the body. No axial load is sustained by the pins, substantially reducing the risk of losing parts downhole.
Optimum cleaning is ensured by nozzles strategically positioned between reaming arms.
Drillstar can custom build a hole opener to specific applications, consult our sales team for more information.
