The 3M Finishing System is a line of orbital sanders and related products intended to reduce dust levels. The abrasive pads of the 3M Finishing System have a multihole pattern that the manufacturer claims is more effective at containing dust than the traditional five- or six-hole design. The Finishing System’s filter bags contain electrostatically charged Filtrete fibers that draw dust particles into the bag’s weblike material. These orbital sanders can be used on wood, metal, automotive paint and composite surfaces. 3M; 888-364-3577; www.3m.com
