Use the Makita SG1251J to hide water pipes and electrical piping in a concrete wall or floor. The powerful 1,400-watt wall chaser is also the ideal tool to make slots in stone, concrete, plasterboard, and sand-lime. Thanks to the soft start, the cutter starts slowly and even maintains its high speed of 10,000 revolutions per minute under heavy load. You can set the thickness of the groove with 9 settings ranging between 6 and 30 millimeters. Lock the switch if you want to work continuously. You don't have to worry about a nasty kickback: the SJS security system absorbs the shocks when the discs gets stuck. In short, the SG1251J is a wall chaser that meets all the requirements of a professional.
