Weka SR75S Core Drill 26" - 14AMP|3PH|480V - Rig-Mounted

Large-diameter core drilling through structural concrete demands equipment that delivers consistent power without overheating during extended cuts. The Weka SR75S handles 26-inch diameter cores with a 14-amp, three-phase 480V motor designed for rig-mounted stability on job sites requiring multiple deep penetrations. This configuration eliminates the limitations of handheld drilling when creating openings for HVAC systems, elevator shafts, or large utility chases in commercial buildings. The industrial three-phase power supply maintains steady torque through reinforced concrete and keeps the motor running cool during back-to-back drilling operations. Rig mounting provides the anchored support necessary for controlling large-diameter bits and reduces operator fatigue on multi-hole projects. Built for concrete cutting contractors and mechanical trades working on commercial construction sites where large penetrations are standard scope.
