3M 7000044828 Diamond Lapping Film Disc 5 Inch

Product Description

The 3M 7000044828 is a 5-inch diameter diamond lapping film disc designed for precision finishing on extremely hard materials. It features precisely graded diamond particles coated onto a polyester film backing, delivering a consistent and repeatable surface finish across a wide range of micron grades from 0.10 to 30.0 micron. This disc is the most widely used diamond lapping film in its category and is suited for high-throughput applications where surface flatness and edge sharpness are critical. Licensed tradespeople and precision machinists rely on this disc for demanding finishing tasks.

This diamond lapping film disc is used in applications requiring tight surface tolerances on hard materials such as ceramics, carbides, optical components, and hardened metals. It is available as an individual disc for use in both manual and machine lapping setups. The uniform diamond coating ensures consistent material removal rates, making it appropriate for production and repair environments alike. It is sold individually, with a minimum order quantity of 25 units.
