3M 7010298836 Diamond Lapping Film Disc 12 Inch

Product Description

The 3M 7010298836 is a 12-inch diameter diamond lapping film disc engineered for precision surface finishing on extremely hard materials. Precisely graded diamond particles are coated onto a durable polyester film backing, delivering a consistent and repeatable finish with each use. The disc is available in several grades ranging from 0.10 to 30.0 micron, allowing technicians and fabricators to select the appropriate cut for their specific application. It is used in professional settings where surface geometry, flatness, and edge definition are critical to part performance.

This lapping disc is suited for applications involving extremely hard substrates such as ceramics, carbides, optical components, and precision-machined metal surfaces. The polyester film construction provides dimensional stability during use, supporting flatter surface results and sharper edge retention. The 12-inch diameter format fits standard lapping machines used in industrial and precision manufacturing environments. Minimum order quantity is 10 discs per order.
