The MK-S is a handheld scoring saw for decorative concrete. Built with high-grade aluminum, the saw has adjustable guides for different operator positions and an easily adjusted cutting depth to a maximum of 1 1/2-in. Front and rear roller guides make it easy to follow chalk lines or pounced patterns. A spring-loaded head allows the user to push the blade down to cut and then automatically retracts the blade when not in use. An optional pivot base can be used for radial cuts. The MK-S has a dust shroud built around the blade.
