Interface pads mount in between the sandpaper and the sander pad and cushion the sanding operation. The 5 mm (3/16") thick pad is used when sanding lightly curved surfaces. It helps smooth curves and reduce the risk of sanding through edges. The 15 mm (9/16") thick pad is used for heavier curves.
These pads are used on Festool's 150m (6") round pad sanders - models RO 150, ETS 150, ES 150 & ETS EC 150. The Multi-Jetstream 2 hole pattern is compatible with all Festool sanders and abrasives, even older patterns.
