The Sawtec hand-held Dekrasaw from Blastrac is designed for the decorative concrete industry and can be used by one person to cut and score decorative lines into concrete. This 110-volt saw is composed of an aluminum base and features an optional pivot base that can be used for radial cuts to create geometric shapes, arcs and circles. For safety and conveniences, a spring-loaded head allows users to easily push the blade down to cut and then automatically retracts the blade when not in use. The cutting depth is adjusted with a thumb screw requiring no tools.
