3M 7010328240 Abrasive Belt 248x4 in 60 Grit Ceramic Ao

Product Description

The 3M 7010328240 is a coated abrasive belt designed for high-production stock removal and metal finishing applications. It uses a blend of 3M ceramic abrasive grain and aluminum oxide, a combination that cuts faster and lasts longer than conventional aluminum oxide alone. The heavyweight polyester cloth backing handles high-pressure contact and can be run wet or dry, making it well suited for heat-sensitive metals such as stainless steel. A built-in grinding aid reduces heat buildup during aggressive grinding cycles. This belt measures 248 inches in length and 4 inches in width, with a 60-grit cut rate.

This belt is used in metal fabrication, weld blending, and surface conditioning on ferrous and non-ferrous metals. It is appropriate for stationary belt grinders and wide-belt machines operating in industrial and shop environments. The 60-grit designation positions it in the coarse-to-medium range, making it effective for initial stock removal before transitioning to finer grits. Maintenance technicians, fabricators, and machine operators in metalworking shops are the primary users.

Key Features

• Ceramic and aluminum oxide grain blend delivers faster cut rates and longer service life than standard AO belts
• Heavyweight polyester cloth backing supports high-pressure grinding applications
• Runs wet or dry, compatible with water- or oil-based lubricants
• Built-in grinding aid reduces heat generation, especially on stainless steel
• Durable resin bond resists heat deterioration to extend belt life and reduce changeover frequency

Compatibility

Designed as an OEM-style coated abrasive belt for belt grinders and wide-belt machines accepting a 248-inch by 4-inch belt in 60 grit.

Installation Notes

Belt installation and tensioning should be performed by qualified shop personnel following the grinder manufacturer guidelines. Power down and lockout the machine before mounting or removing the belt. Confirm proper tracking adjustment before resuming operation. Run the belt at the speed rating specified by the machine manufacturer to avoid premature failure or unsafe conditions.
