3M 7000045627 Quick-change Disc 2in 50 Grit Ceramic Roloc Tr

Product Description

The 3M 7000045627 is a ceramic-abrasive quick-change disc designed for aggressive material removal on metal, weld seams, and surface preparation work. Built on a polyester cloth backing with a YF backing weight, the disc uses a Type R (Roloc TR) attachment system for fast, tool-free changes on compatible inline and angle grinders. At 50 grit, this is a coarse-grade disc suited for rapid stock removal rather than finishing. The disc is rated to 25,000 RPM and weighs approximately 0.01 pounds. The orange ceramic grain and cloth construction are engineered for durability under sustained pressure.

This disc is commonly used in fabrication shops, welding operations, and maintenance environments where fast surface conditioning, rust removal, or weld blending is required. The 2-inch diameter makes it well-suited for tight access areas and detailed work on metal components. It is typically installed and operated by metal fabricators, maintenance technicians, and industrial grinding professionals using Type R quick-change tool attachments.

Installation Notes

Installation is performed by threading the disc button onto a compatible Type R mandrel until secure. Always confirm the tool and mandrel are rated for at least 25,000 RPM before mounting the disc.
