Remember when you had the smoothest drywall in town? The WEN 20V Brushless Handheld Drywall Sander with 4.0Ah Battery and Charger makes sanding drywall easier than ever. Powered by a 20V Lithium battery pack, this tool can operate quietly and efficiently without cords, and the brushless motor delivers a longer runtime and greater longevity. The included 4.0 amp-hour lithium-ion battery delivers consistently powerful performance at any level of charge, features an onboard LED charge gauge, and is cross-compatible with the entire WEN 20V Max Lithium-Ion Cordless Power Tool line. The variable speed adjustment can operate between 600 and 1200 RPM, which you can track using the handy LED indicator. And using the last speed memory function, the sander will remember where you left off on your latest project. Switch easily between rough and fine sanding with the stationary and floating sanding pad modes. You'll be able to handle automatic dust removal with the included dust hose and collection bag, and connecting to a vacuum using the 1-¼” adapter has never been easier. This sander is compatible with the entire DW-series of sandpaper, including models DW60SP, DW80SP, DW120SP, DW150SP, DW180SP, DW240SP, DW400SP. The sander's packing list includes eight hook-and-loop sanding discs (two 150-grit pieces, two 180-grit pieces, two 240-grit pieces, and two 400-grit pieces). And because it's a WEN product, your Variable Speed Drywall Sander comes backed by a two-year warranty, a stocked inventory of replacement parts, and a friendly customer helpline, all to make sure you remember WEN.
