3M 7000045128 Diamond Microfinishing Film Roll 4x50ft

Product Description

The 3M 7000045128 is a diamond microfinishing film roll engineered for superfinishing and rapid finish reduction on exceptionally hard materials. Diamond mineral is bonded directly to a polyester film backing, producing a consistent, durable abrasive surface that maintains cutting performance across the full length of the roll. The roll measures 4 inches wide by 50 feet long and is configured for 60-inch infeed and outfeed machine setups. This product is suited for precision finishing operations where tight surface-finish tolerances are required on the workpiece.

This microfinishing film roll is designed for use on hard and difficult-to-finish materials including thermal spray coatings, ceramics, carbides, chilled iron, and granite. It is commonly used in industrial and precision machining environments where conventional abrasives fall short. The 60-inch infeed and outfeed configuration makes it compatible with automated superfinishing and lapping machine setups. Skilled machinists, toolroom technicians, and surface-finishing specialists are the primary installers and operators of this consumable abrasive product.
