3M 7100264239 Air Orbital Sander 5 Inch Round Pad

Product Description

The 3M 7100264239 is a pneumatic random orbital sander built for professional surface preparation and finishing applications. It accepts a 5-inch round pad and uses a Hookit Conversion Disc Backing Pad system, allowing fast disc changes without adhesives. The sander runs at 12,000 RPM with an orbit diameter of 5/16 inch (0.313 inches), producing a fine, swirl-minimizing finish pattern suited to automotive bodywork, woodworking, and industrial surface prep. Air consumption is 6.2 CFM at 94.17 psi. At 2.56 pounds, it is lightweight enough for extended overhead or detail work. Licensed trades and experienced DIYers who demand consistent stock removal and finish quality rely on this tool for paint prep and primer leveling.

This sander is designed for shop and field use where compressed air is available. It fits naturally into automotive refinishing, cabinetry, and general industrial finishing workflows. The random orbital action reduces cross-grain scratching and loading compared to straight-line sanders. The Hookit Conversion Disc Backing Pad configuration lets the operator swap between Hookit and standard hook-and-loop discs, expanding abrasive compatibility on the same tool body. It is sold as a single unit.

Installation Notes

Connection to a compressed air supply line should be made by a qualified operator following the tool manufacturer's safe operating procedures. Verify the air supply pressure and CFM capacity before connecting to ensure the compressor meets the 6.2 CFM at 94.17 psi requirement. Disconnect the air line before changing abrasive discs or performing any inspection of the tool. Follow applicable OSHA standards and shop safety protocols when operating pneumatic abrasive tools.
