3M 7100098418 Diamond Lapping Film Disc 12 Inch

Product Description

The 3M 7100098418 is a 12-inch diameter diamond lapping film disc engineered for precision surface finishing on extremely hard materials. Precisely graded diamond particles are coated onto a polyester film substrate, delivering a consistent, repeatable surface finish across each use. Grades range from 0.10 to 30.0 micron, giving technicians control over material removal rate and final surface quality. This disc is well suited for lapping and polishing applications where flatness, edge sharpness, and finish uniformity are critical requirements.

This diamond lapping film disc is used across industries and applications that require controlled, repeatable finishing of hard substrates such as ceramics, glass, carbide, and precision-ground metal components. It is appropriate for both production environments and controlled finishing operations where throughput and surface consistency matter. The film-backed construction supports flat-lap and free-hand lapping setups alike.

Key Features

• Precisely graded diamond particles on polyester film for uniform, repeatable finish
• Fast cut rate supports increased throughput in production finishing
• Produces flatter surfaces and sharper edges compared to conventional abrasive films
• Available in grades from 0.10 to 30.0 micron to match specific finish requirements
• Disc format compatible with flat-lap equipment and manual lapping fixtures

Compatibility

Designed as a precision lapping film disc for use on extremely hard materials including ceramics, carbide, glass, and hardened metals where a consistent, controlled finish is required.

Installation Notes

Installation and use of lapping film discs should be performed by qualified technicians familiar with abrasive finishing processes. Ensure the lapping plate or fixture surface is clean and flat before mounting the disc to avoid uneven wear or inconsistent finish results. Inspect the disc for damage before each use and replace when abrasive performance degrades. Follow all applicable workplace safety guidelines for abrasive operations, including eye protection and dust control.
