Festool 578057 Base LAS-OF 1010 R features a transparent and tilt-resistant design that ensures a view of the workpiece when used with the light ring. Its small opening allows for reliable guidance of the router even in corners, preventing tipping. This base provides steady and precise working thanks to a small center hole and a continuous running surface. The adjustable hole diameter can be enlarged to match the cutter diameter by plunge-cutting with the router. Additionally, the light-transmissive base optimally illuminates the work area when combined with the LED light ring. It is i for routing in edge areas or corners and for working along a scribe mark.
