3M 7010325484 Diamond Lapping Film Disc 12 Inch

Product Description

The 3M 7010325484 is a 12-inch diameter diamond lapping film disc designed for precision surface finishing on extremely hard materials. Precisely graded diamond particles are bonded to a durable polyester film substrate, producing a consistent, repeatable finish across every pass. This disc is widely used in applications where tight surface tolerances and sharp edge retention are critical. Licensed tradespeople and precision finishing technicians working with ceramics, carbide, glass, and similar hard substrates rely on this disc for controlled stock removal and predictable results.

This lapping film disc suits precision grinding and finishing operations in industrial, optical, and tool-and-die environments. It performs in both wet and dry lapping setups and is available in grades ranging from 0.10 to 30.0 micron, allowing technicians to progress through finish stages without switching product families. The 12-inch diameter fits standard lapping machines and flat-lap systems used in professional finishing shops.

Key Features

• Precisely graded diamond abrasive particles deliver a uniform, repeatable surface finish
• Polyester film backing provides dimensional stability and resistance to tearing under load
• Fast cut rate increases throughput compared to conventional abrasive films
• Produces flatter surfaces and sharper edges on hard materials
• Available in multiple grades from 0.10 to 30.0 micron for progressive finishing
• 12-inch disc format fits standard flat-lap and lapping machine platens

Compatibility

Designed for use on extremely hard materials including ceramics, carbide, glass, and similar substrates; fits standard 12-inch lapping machine platens used in precision finishing applications.

Installation Notes

Mount the disc onto a clean, flat platen surface, ensuring no debris is trapped beneath the film before securing. Technicians should inspect the platen for flatness before each disc change, as surface irregularities will transfer to the workpiece finish. Follow the lapping machine manufacturer's guidelines for disc adhesion method and platen speed. Dispose of worn discs per facility waste handling procedures, as diamond abrasive media may be subject to local disposal regulations.
