3M 7010325487 Microfinishing Film Roll 100 Micron 18x150ft

Product Description

The 3M 7010325487 is a silicon carbide microfinishing film roll designed for precision surface finishing applications. Built on a durable polyester film backing, this Type E 468L roll delivers consistent, micron-graded cutting action across its full 18-inch width and 150-foot length. The 100-micron grit rating makes it well suited for fine stock removal and surface preparation work where tight finish tolerances are required. Machinists, tool-and-die technicians, and production finishing specialists rely on film-backed abrasives like this for controlled, repeatable results on metal and other hard substrates.

This roll is used in production and job-shop environments for applications such as lapping, superfinishing, and precision grinding of metal components. The unbacksized construction and film substrate provide dimensional stability under tension, making it compatible with roll-fed finishing equipment and wide-belt setups. It is appropriate for use on ferrous and non-ferrous metals where surface finish consistency is critical to part performance or inspection requirements.

Key Features

• Silicon carbide abrasive mineral for hard, brittle material cutting and fine surface finishing
• 100-micron grit rating for controlled stock removal and tight finish tolerances
• Polyester film backing provides dimensional stability and resistance to tearing under load
• Type E 468L construction — unbacksized roll format for use with roll-fed and wide-belt equipment
• 18-inch width and 150-foot length minimize changeover frequency in production runs
• 3-inch core accommodates standard roll-fed finishing machine mandrels

Compatibility

Designed for use with roll-fed and wide-belt surface finishing equipment that accepts an 18-inch-wide, 3-inch-core abrasive roll. Consult equipment specifications to confirm feed tension and contact-roll compatibility before use.

Installation Notes

Loading should be performed by a qualified machine operator following the equipment manufacturer's roll-change procedure. Disengage and lock out all power to the finishing machine before threading the new roll. Ensure proper tracking alignment and tension settings before resuming production. Wear appropriate eye and hand protection when handling abrasive rolls, as edges and the abrasive surface can cause lacerations.
