3M 7010307685 Diamond Lapping Film Disc 4.125 in

Product Description

The 3M 7010307685 is a diamond lapping film disc designed for precision surface finishing on extremely hard materials. Precisely graded diamond particles are coated onto a polyester film substrate, producing a consistent, repeatable finish across each use. The disc measures 4.125 inches in diameter and weighs 0.01 pounds. It is suited for applications requiring tight surface tolerances and sharp edge definition, making it a reliable choice for tool shops, optical component finishing, and precision manufacturing environments where surface quality is critical.

This diamond lapping film disc is used in precision lapping and finishing operations where hard substrates such as ceramics, carbides, glass, and hardened metals require controlled material removal. The polyester film backing provides dimensional stability during use. Sold individually, this disc fits into workflows that demand high repeatability and uniform surface texture across production runs or repair applications.

Key Features

• Precisely graded diamond abrasive particles bonded to a polyester film backing
• Produces flat surfaces and sharp edges on extremely hard materials
• Delivers a consistent, repeatable finish across multiple uses
• Fast cutting action supports increased throughput
• Available in multiple grades ranging from 0.10 to 30.0 micron

Compatibility

Designed as a precision lapping disc for use on extremely hard materials including ceramics, carbides, glass, and hardened metal surfaces where controlled, repeatable finishing is required.

Installation Notes

Installation and use of lapping film discs is typically performed by precision machinists or finishing technicians. Ensure the lapping plate or fixture surface is clean and free of debris before mounting the disc. Use appropriate backing plates and light, controlled pressure to avoid tearing the polyester film substrate. Follow all applicable shop safety procedures when working with abrasive materials.
