3M 7000044830 Diamond Lapping Film Disc 5 Inch

Product Description

The 3M 7000044830 is a 5-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, repeatable finish with every pass. This disc is widely used in applications demanding flat surfaces, sharp edges, and uniform finishes across a range of micron grades from 0.10 to 30.0 micron. Technicians and finishing specialists rely on this disc where conventional abrasives fall short on hardness or consistency.

This diamond lapping disc is suited for professional and industrial finishing operations involving hard substrates such as ceramics, carbide, glass, and optical components. Its design supports high throughput workflows where repeatable surface quality is critical. The disc format makes it compatible with standard lapping machines and rotary finishing equipment used in production and service environments. It is sold individually and available in multiple grade options to match specific finishing requirements.
