Downhole Innovations, Made in France HOME DRILLSTAR OIL AND GAS SUBCONTRACTING NEWS & MEDIA CONTACT PDC HOLE OPENER PDF info sheet IMPROVE YOUR HOLE OPENING PERFORMANCES Drillstar PDC hole opener is a reliable solution for hole enlarging in both medium and hard formations. The body is machined out of a single block of heat treated AISI 4145H alloy steel. The three PDC arms are held in place by oversized locking pins. The unique design of the body ensures maximum strength and durability. It can withstand loads far beyond those involved during normal drilling operations. Cutting arms are fitted with two rows of PDC. During drilling, load is transferred directly from the arms to the body. No stress is sustained by the pins, substantially reducing the risk of losing parts downhole. Optimum cleaning is ensured by nozzles positioned below each cutting arm. Different sizes of arms can be adapted to the same body: for example the 9 1/2″ OD body can be fitted with optional arms to enlarge up to 22″ or 26″. Special sizes of body and arms are available on request.
