DWE6421K DeWalt 5" SINGLE SPEED RANDOM ORBIT SANDER KIT - H&L PAD | The DWE6421K 5 in single-speed random orbit sander kit with hook-and-loop pad has a 3 A 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 dust collectors.
