3M 7100138346 Random Orbital Sander 6 in Self-vacuum

Product Description

The 3M 7100138346 is a 6-inch random orbital sander with a 5/16-inch orbit and a self-generated vacuum system. It is designed for surface preparation, finish sanding, and material removal on wood, metal, composites, and painted surfaces. The sander ships with a Hookit pad, a filter bag adapter, and a clean sanding filter bag, giving technicians and finish carpenters an integrated dust-capture setup out of the box. The self-generated vacuum draws dust directly through the pad and into the filter bag, reducing airborne particulate and keeping the work surface visible during operation. At 2.35 pounds, the tool is light enough for extended use overhead or on vertical surfaces.

This sander is suited for professional woodworking shops, automotive body preparation, and general surface finishing in both residential and light commercial settings. The 6-inch pad size and 5/16-inch orbit pattern make it appropriate for aggressive stock removal as well as finer finish passes depending on the abrasive selected. Finish carpenters, auto body technicians, and general contractors are the primary installers and operators of this tool.
