Best forYou want a cordless sander at 3600 RPM and can confirm battery and pad details separately.

3600 RPM on battery power is workable for light sanding, but confirm battery capacity and sanding pad size before buying since neither is listed.

Overview

A battery powered sander from model MRS322, running at 3600 RPM. The brand field on this listing just reads Electric, so treat MRS322 as the identifying model number.

Beyond speed and power source, the amperage figure listed for this sander does not hold up (750 amps is far outside what a handheld sander draws), so that spec is left out here rather than repeated as fact.
