3M 7100010674 Abrasive Belt 1/2x18 in Aluminum Oxide Medium

Product Description

The 3M 7100010674 is a non-woven abrasive belt designed for precision surface finishing on metal, wood, and composite materials. Part of the DF-BL series, it measures 1/2 inch wide by 18 inches long and uses aluminum oxide abrasive at a medium grade. The low-stretch backing maintains consistent contact pressure across the workpiece, reducing the risk of uneven material removal. This belt supports both wet and dry operation, giving technicians flexibility depending on the application or finish requirement. It is a consumable replacement belt intended for use in belt-driven finishing tools and portable belt sanders used in fabrication and maintenance trades.

This abrasive belt is suited for light deburring, blending, and surface conditioning tasks in residential and commercial maintenance, HVAC fabrication, plumbing rough-in, and general metalworking environments. The 1/2-inch width makes it compatible with narrow-profile belt sanders and inline finishing tools commonly used in tight spaces or on small-diameter tubing and fittings. Medium grade aluminum oxide provides an effective balance between material removal rate and surface finish quality for general-purpose work.

Installation Notes

Belt replacement should be performed with the tool powered off and unplugged. Inspect the drive and idler rollers for wear or debris before installing a new belt. Ensure the belt tracking is properly adjusted after installation before resuming operation. Follow the tool manufacturer guidelines and applicable workplace safety standards when operating abrasive belt equipment.
