Powerful & Efficient Slotting With a highperformance pure copper motor up to 5500W load power, sharp saw blades, and speeds up to 6500 rpm, it can cut marble, concrete, brick, etc. with ease and high efficiency. Adjustable Design: By adjusting the plate and changing the number of blades, you can make it slot up to 1.61 inches deep and 1.65 inches wide for ideal slotting results. Flexible Operation: The non-slip 180° adjustable front handle and 90° rotatable rear handle allow you to groove from different angles and directions to meet different work requirements. Accurate Cutting: The laser positioning design provides guidance for slotting in the correct direction and greatly reduces slotting errors, resulting in straighter lines and accurate cutting work. Dual Dust Removal Design: The water pump with a 16.4ft hose delivers water quickly, increases cutting efficiency, reduces dust splatter during the cutting process, and decreases blade temperatures while prolonging the life of saw blades.
