3M 7010307672 Diamond Lapping Film Disc 12 Inch

Product Description

The 3M 7010307672 is a 12-inch diameter diamond lapping film disc designed for precision surface finishing on extremely hard materials. Precisely graded diamond abrasive particles are coated onto a durable polyester film backing, producing a consistent and repeatable finish pass after pass. The disc is suited for applications demanding tight surface tolerances, flat geometry, and sharp edge retention. Licensed tradespeople and precision machinists use this disc in lapping and polishing operations where conventional abrasives fall short on hardness or finish consistency.

This lapping film disc is used across applications involving ceramics, carbides, optical components, fiber optic connectors, and other hard substrates that require controlled material removal and a uniform surface finish. It fits into standard disc-style lapping and polishing setups found in industrial and precision manufacturing environments. The disc is available in grades ranging from 0.10 micron to 30.0 micron, allowing the technician to select the appropriate cut rate and finish level for the job.

Key Features

• Precisely graded diamond particles bonded to a polyester film substrate for a consistent, repeatable finish
• Fast cut rate supports increased throughput on hard materials
• Promotes flatter surfaces and sharper edges compared to conventional abrasive films
• Uniform finish across the full 12-inch disc surface
• Available in multiple grades from 0.10 to 30.0 micron for versatile application coverage
• Also available in sheet and roll formats for other fixturing requirements

Compatibility

Designed for use with standard 12-inch diameter disc lapping and polishing equipment used on extremely hard materials including ceramics, carbides, and optical substrates.

Installation Notes

Mount the disc on a flat, clean lapping plate or backing pad appropriate for 12-inch disc tooling. Ensure the backing surface is free of debris before applying the disc to prevent uneven contact and inconsistent finish results. Follow equipment manufacturer guidelines for speed and pressure settings when working with diamond lapping films. Proper fixture loading and workpiece seating are critical to achieving the flat surface geometry this product is engineered to deliver.
