Product Description

The 3M 7100240707 is an aluminum oxide cloth-backed abrasive belt in the 384F series, measuring 52 inches x 75 inches with an XF-weight polyester backing. It is built for general-purpose grinding, deburring, and finishing on metal and wood substrates. The resin bond system holds up under high heat and pressure, making it a dependable choice for production metalworking and finishing environments. This belt is suited for use by metalworkers, fabricators, and industrial maintenance techs running backstand, benchtop, stroke, or wide belt grinding equipment.

The 384F belt is optimized for mild steel and carbon steel deburring and general metalworking. It also performs reliably on softer metals including aluminum, bronze, and brass, as well as on select woodworking applications. The Sine-lok and Single-flex construction allows the belt to conform and track consistently across a range of machine configurations, including portable belt grinders and wide belt finishing machines.
