With the Festool 438608 support foot, you maintain complete balance and precision when routing along a guide rail. Designed for your Festool of 1 e or of 1010 router, this support offsets the height difference between the rail and the workpiece surface. It keeps your router flat and prevents tipping or drifting during grooving and rebating jobs. Quick and easy to attach directly to your machine, this replacement support foot delivers steady, repeatable guidance across every cut so you can work with total control.
