3M 7010360191 Diamond Lapping Film Disc 12 Inch

Product Description

The 3M 7010360191 is a 12-inch diameter diamond lapping film disc designed for precision surface finishing on extremely hard materials. Precisely graded diamond abrasive particles are coated onto a dimensionally stable polyester film backing, producing a consistent, repeatable finish across each pass. This disc is widely used in applications where surface geometry and edge integrity are critical. Technicians working with ceramics, carbide, optical components, or hardened tool steel rely on this format for controlled stock removal and flat, uniform surface generation.

This disc fits lapping and polishing operations in manufacturing, tool and die, optical fabrication, and precision machining environments. It is suited for both wet and dry lapping setups on surface plates, lapping machines, and rotary finishing equipment. The 12-inch diameter format accommodates standard lapping platens common in industrial and laboratory settings. Available diamond grades range from 0.10 to 30.0 micron, allowing selection of the appropriate grit for roughing, semi-finishing, or final polishing stages.

Key Features

• Precisely graded diamond particles for controlled, repeatable material removal
• Polyester film backing provides dimensional stability and resistance to tearing
• Produces flat surfaces and sharp edges on hard materials
• Uniform finish across the full disc surface
• Available in grades from 0.10 to 30.0 micron to suit multiple finishing stages
• Also available in sheets and rolls for alternative application formats

Compatibility

Designed for use on extremely hard materials such as ceramics, carbide, optical glass, and hardened metals. Fits standard 12-inch lapping platens and rotary finishing equipment. Specific system or machine compatibility was not provided in the product data.

Installation Notes

This disc is installed by trained technicians or machinists on lapping machines or surface plates. Secure the disc to the platen using the appropriate adhesive, magnetic, or pressure-sensitive mounting method required by the equipment. Inspect the disc for uniform seating before beginning any lapping cycle. Follow the equipment manufacturer guidelines and applicable shop safety procedures when operating lapping and polishing machinery.
