The DWE6421 5" Single Speed Random Orbit Sander with hook & loop pad has a 3 amp motor that delivers 12,000 OPM. The separate counterweight reduces vibration and along with the rubber overmold grip provides comfortable sanding. A shorter design allows users to get closer to the work surface and the one-handed locking dust bag attaches securely to the sander to aid in dust collection or the user can attach the sander directly to the DWV010 or DWV012
