Drill 6-inch diameter holes with hydraulic core drill

Power CS Unitec‘s three-speed hydraulic core drill with a hydraulic power pack or from the hydraulic fluid of large machinery using a pressure and flow regulator. The drill requires 6 gpm oil flow for operation. The 3.6-horsepower hydraulic core motor weighs just 16 pounds and drills 1/2- to 6-inch diameter holes. The 47-pound model, rig-mounted on a stand, drills through concrete and reinforced concrete. Both models function underwater. The hydraulic motor has a self-regulating oil flow control up to 13 gpm.
