The SSR75 MOTOR is a motor for diamond core drills, suitable for stand-mounted use and for drilling holes in materials such as rock, concrete, asphalt and masonry. The motor is fitted with a ball valve which supplies water both to cool the motor itself and to flush away the drilling slurry. The motor features 3 mechanical speeds. For each mechanical speed, 6 electronic speeds are available, selectable via the buttons on the control panel. This allows the user to core drill at the speed best suited to the hole diameter.
