Ideal for electrical installations for laying cables and conduits under plaster with cutting depths of up to 40 mm. Maximum work progress is achieved thanks to a powerful motor, constant speed, and a two-speed high-performance gearbox. The robust die-cast aluminum bonnet features rubber rollers and an optimum handle position for comfortable guidance of the machine. A sliding cut provides optimum visibility of the marking line. The channel width and cutting depth are adjustable. The Metabo Marathon motor includes patented dust protection for a long service life. Tacho-Constamatic (TC) full-shaft electronics ensure fast work progress with constant speed under load. An electronic soft start and restart protection enhance safety during operation. An LED signal indicates overload or active restart protection. The connection of a Metabo all-purpose vacuum cleaner ensures clean, low-dust operation. It is suitable for slotting grooves up to 30 mm wide without center in a single operation (with special accessory) and can also cut with just one diamond cutting disc. The Metabo S-automatic safety clutch provides mechanical decoupling of the drive for safe operation if the disc stops unexpectedly. The adjustable cutting depth ranges from 10 to 40 mm (3/8 to 1 9/16 inches), with possible groove widths of 9 mm, 15.5 mm, 22 mm, 28.5 mm, and 35 mm (3/8", 5/8", 7/8", 1 1/8", 1 3/8").
