Soft interfaces allow for more forgiving rotary sanding to prevent harsh divots and ripples in your work surface.

Interface pad for rotary sanding; makes it easier to sand curved surfaces. Interfaces with holes aid with dust extraction systems but also with keeping interfaces and backing plates cooler when in use at the sacrifice of some foam integrity. Not meant for use at high RPM. These interfaces are too soft for use on hard, flat surfaces like stainless steel – use a backing pad alone.
