3M 7000045130 Diamond Microfinishing Film Roll 675L

Product Description

The 3M 7000045130 is a diamond microfinishing film roll designed for superfinishing and fast finish reduction on hard materials. Diamond mineral is bonded to a durable polyester film backing, delivering consistent cut and surface finish in demanding applications. The roll measures 4 inches wide by 50 feet long with a 3-inch core, and is configured for 60-inch infeed and outfeed machine setups. This product is used by machinists, grinding technicians, and precision finishing professionals working with extremely hard substrates.

This microfinishing film roll is suited for industrial and precision manufacturing environments where tight surface finish tolerances are required. Target materials include thermal spray coatings, ceramics, carbides, chilled iron, and granite. The 675L construction is engineered for high-precision lapping and superfinishing operations on CNC or manual finishing equipment configured with a 60-inch feed path.
