The Dynabrade Rotary/Random Orbital Sanding Head allows users to switch from rotary to random orbital action with the push of a button. The head is available in a 5/8"-11 female thread size to fit virtually all buffers up to 3,200 RPM. Utilizing either an electric or air-powered tool, the user operates the pad in a rotary (cut) mode for initial buffing. Switch to the random orbital (polish) mode for buffing to a swirl-free finish with the push of a button.
