Designed for crack repair in concrete and asphalt surfaces, the CS8 Random Crack Saw features 8-in. diameter dry cut-type diamond blades in a center-mounted blade configuration that produce smooth-sided cuts by pivoting on its own axis. An 11-hp Honda engine with Cyclone-type air filter system and 3-in.-diameter vacuum dust control port provide protection against fine-grained dust. An optional water mist control system is available for wet sawing applications. General Equipment. 800-533-0524.
