Overview

The Dynabrade 59020 is an air-powered sander weighing 0.65 kilograms and running at 12,000 RPM. It holds a 4.7 star rating from 173 reviews, with about 50 bought in the past month.

As an air tool, it needs a shop compressor and air line rather than a cord or battery, which is common for Dynabrade's line of pneumatic finishing tools. The amperage figure in the spec data appears to be a leftover template field and does not apply to a pneumatic tool; the air-powered listing is the operating spec that matters here.

Who it's for

Works for auto body shops, woodworking shops and anyone already set up with compressed air who wants a lightweight sander for fine finishing work. Not a fit for someone without a compressor, since it will not run on its own.
