Our line of 3M™ elite central-vacuum-ready random orbital sanders deliver professional, dust-free performance along with a swirl-free finish, hour after hour in high production industrial environments where dust extraction is required. Our line of 3M™ elite central-vacuum-ready random orbital sanders are best-in-class tools designed to optimize the performance of 3M™ abrasives. Built with a powerful, precision balanced air driven motors and durable lightweight aluminum housing, these ergonomically designed workhorses stand upto industrial production and reduce user fatigue for hours of comfortable operation. Elite central-vacuum-ready sanders can be connected to a central vacuum system or used with an external portable vacuum such as a shop vacuum. It has a threaded attachment feature that enables easy yet secure attachment and detachment of a 1 in external threaded vacuum hose (sold separately) to effectively eliminate dust from the workpiece and surrounding space. Designed with the operator in mind, 3M™ elite central-vacuum-ready random orbital sanders are loaded with ergonomic features that decrease work strain and improve productivity. 3M™ random orbital sanders optimize sanding and surface preparation on wood, metal, fiberglass and composite materials and many other substrates. Also known as dual action (D/A) palm sanders, these industrial grade tools rotate the abrasive disc and disc pad in two simultaneous overlapping oval patterns so no single abrasive particle follows the same path twice, producing a random scratch and swirl-free finish ready for paint or varnish.
