During the Holiday Pay deals from 21 May to 9 June, Coolblue has the best sander promotions. Sand large surfaces with an eccentric or delta sander. With the delta sander, you can also easily sand small corners because of its pointed sanding pad. For smooth sanding walls and floors, use a drywall sander. Want to do several sanding jobs? A multi-sander is the best choice for you. That way, you can be sure you have the right sander for every job.
