Invented and perfected by Festool: The guide rail. For making cuts and grooves with impressive precision. With slideway lining for guaranteed machine smoothness, a groove for screw and lever clamps and splinter guard for splinter-free sawing. Making breakthroughs in precision and convenience since 1964. The original is available in eight different lengths from 800 to 5000 mm. Zero-play guidance – you can adjust the guidance jaws on the circular saw to fit the guide rail without using tools Splinter-free cuts – the splinter guards positioned directly on the scribe line prevent the edges from splintering, even on angled cuts Precision results – the router guide stop was designed for precision grooves Quick for diagonal cuts – with guide rail and combination bevel, angles are easy to transfer from the workpiece or wall
