3M 7000044850 Diamond Lapping Film Disc 5 Inch

Product Description

The 3M 7000044850 is a 5-inch diameter diamond lapping film disc designed for precision surface finishing on extremely hard materials. Precisely graded diamond particles are coated onto a polyester film backing, delivering a consistent, repeatable finish across production runs. The disc is available in multiple grades ranging from 0.10 to 30.0 micron, making it suitable for applications that demand tight surface finish tolerances. Licensed tradespeople and precision machining technicians use this disc where conventional abrasives fall short on hard substrates.

This lapping film disc is used in applications requiring flat, uniform surface finishes on hard materials such as ceramics, carbide, glass, optical components, and hardened metals. It is sold individually and is also available in sheet and roll formats for high-volume or custom fixture setups. The 5-inch diameter format fits standard lapping and polishing equipment commonly found in precision manufacturing and optical finishing environments. Minimum order quantity is 25 units per order.

Key Features

• Precisely graded diamond particles on a polyester film backing for consistent finish results
• Fast cut rate increases throughput on hard-material finishing operations
• Produces flatter surfaces and sharper edges compared to conventional abrasive films
• Uniform finish across the disc surface minimizes rework
• Available in grades from 0.10 to 30.0 micron to match specific surface finish requirements
• Also available in sheet and roll formats for flexible application setups

Compatibility

Designed for use on extremely hard materials including ceramics, carbide, glass, and optical substrates; compatible with standard 5-inch lapping and polishing equipment and fixtures.

Installation Notes

This disc is installed by precision machining or optical finishing technicians on lapping plates or polishing fixtures. Ensure the lapping plate or backing surface is clean and free of debris before mounting the disc to avoid surface contamination. Follow equipment manufacturer guidelines for rotational speed and applied pressure appropriate to the workpiece material and target finish grade. Inspect the disc for wear or loading regularly and replace when finish quality degrades.
