Looking for a product that sucks? Look no further than this DEWALT dust extractor, which is currently on a sale at Amazon. The reviews for this product mention its effectiveness in controlling dust. However, the attachment and hose you need to run back to your shop-vac require space, which might be limited on the surface where you are drilling. Hammer drills aren't small, so chances are you'll have enough room for this extractor to be placed and minimize the dust you kick up from your hammer drill.
