3M 7100138345 Random Orbital Sander 5 in Self-vacuum

Product Description

The 3M 7100138345 is a 5-inch random orbital sander designed for professional surface preparation and finish sanding across woodworking, automotive bodywork, and general fabrication applications. It features a self-generated vacuum system that draws sanding dust directly through the pad and into a filter bag, keeping the work surface cleaner and reducing airborne particulate during operation. The sander runs a 3/16-inch orbit, which balances aggressive material removal with a refined finish. The unit ships with a Hookit pad, a filter bag adapter, and a clean sanding filter bag included in the box. At 2.35 pounds, it is lightweight enough for extended overhead or vertical surface work.

This sander is suited for residential and commercial finishing tasks where dust containment is a priority. Typical applications include furniture finishing, cabinet sanding, automotive prep work, and drywall feathering. The self-generated vacuum design eliminates the need for a separate shop vacuum connection during light to medium sanding passes, making it practical for field use or job sites where central vacuum infrastructure is not available.

Key Features

• 5-inch pad accepts standard Hookit abrasive discs for quick disc changes without tools
• 3/16-inch orbit delivers a balance of stock removal rate and surface finish quality
• Self-generated vacuum system channels dust away from the work surface without requiring an external vacuum
• Includes Hookit pad, filter bag adapter, and clean sanding filter bag ready to use out of the box
• Lightweight 2.35-pound body reduces fatigue during extended sanding sessions

Compatibility

Designed for use with 5-inch Hookit abrasive discs compatible with standard random orbital sanders; the included filter bag adapter connects to the sander's built-in vacuum port for contained dust collection.

Installation Notes

Installation and setup should be performed by a qualified tradesperson familiar with pneumatic or electric power tool operation as applicable. Before attaching or removing the sanding pad or disc, ensure the tool is disconnected from its power or air supply. Verify that the filter bag adapter is fully seated before operation to maintain dust containment performance. Follow applicable OSHA respiratory and PPE guidelines when sanding materials that may generate hazardous dust.
