Dynabrade 47820 Air Handheld Disc Sander 2 in 12000 Rpm

Product Description

The DYNABRADE 47820 is a pneumatic handheld disc sander designed for precision surface finishing, deburring, and material removal in tight or confined work areas. Powered by compressed air at 90 psi, it spins at 12,000 RPM and draws 25 CFM at full load, delivering 0.40 HP through a 1/4-20 spindle. The front exhaust design directs air away from the work surface, keeping the workpiece clear during operation. At 4.4 inches overall length and 1.1 pounds, this tool is built for one-handed control in fabrication, assembly, and finishing applications. It ships with a disc sander and wrench.

The 47820 is suited for metalworking, composites, and surface prep tasks where a compact, low-profile pneumatic tool is required. It accepts 2-inch and 3-inch diameter pads, making it versatile across a range of finishing media. Typical use cases include weld seam blending, spot finishing, and edge work on assemblies where larger random-orbit or straight-line sanders cannot reach. It connects via a standard 1/4-inch NPT air inlet, compatible with common shop air setups.
