The Worx WX642 270W 1/3 Sheet finishing sander has an industrial grade aluminium base for a flat precise sanding, and extended durability. The ergonomic design provides improved comfort & control, and the dual quick clamping system / hook & loop system give the convenience and versatility to use a wide range of sand paper. The bagless Worx CDS (Cyclonic Dust Seperator) effectively separates extracted dust from the air. Normal dust filters suffer from loss of suction as they clog with use, with the Worx CDS suction remains constant. The resulting benefit, is that the extraction is more efficient and the air expelled from the CDS system is cleaner for a healthier work environment. As with all Worx DIY tools this machine comes with a free 3 year manufacturer's warranty, (Subject to on line registration with Worx).
