The Max-30 Tube is a completely unique Magnet Drill in that the the magnets do not require electricity, so all of the power goes to the motor. With patented shallow-field magnetic technology that offers incredibly strong grip, even on steel as thin as 3 mm. The patent-pending base automatically pivots to clamp exactly to any pipe diameter 75 mm or larger. This also offers increased safety as the tool will not release from the target material in the event of an unintentional power loss. With a high speed 900W power the Max-30 TUBE cuts holes between 12 and 30 mm diameter quickly and easily. Will also secure to flat surfaces.
