3M 7000044751 Diamond Lapping Film Disc 8 Inch

Product Description

The 3M 7000044751 is an 8-inch diameter diamond lapping film disc designed for precision surface finishing of extremely hard materials. Precisely graded diamond particles are coated onto a polyester film backing, producing a consistent, repeatable finish across demanding applications. The disc delivers fast material removal with a uniform surface profile, making it a reliable choice for technicians and machinists who require tight tolerances and sharp edge retention on hard substrates. It is sold individually and is part of a product family available in multiple grades ranging from 0.10 to 30.0 micron.

This disc is suited for lapping and polishing operations on ceramics, carbide, glass, optical components, and other hard materials where conventional abrasives fall short. It is commonly used in precision manufacturing, tool and die work, optical finishing, and fiber-optic connector polishing environments. The polyester film backing maintains dimensional stability during use, helping achieve a flat surface and consistent finish across the entire working area.

Key Features

• Precisely graded diamond abrasive particles bonded to a stable polyester film backing
• Delivers fast cut rates for increased throughput on hard materials
• Produces flatter surfaces and sharper edges compared to conventional abrasive films
• Uniform finish across the full 8-inch disc surface
• Available across multiple grades from 0.10 to 30.0 micron for application-specific finishing
• Compatible format for use in disc, sheet, and roll configurations within the same product line

Compatibility

Designed for use as a lapping and polishing disc on hard materials including ceramics, glass, carbide, and optical components in precision finishing applications.

Installation Notes

This disc is installed and used by precision machinists, optical technicians, and tool and die professionals on lapping machines or rotary polishing fixtures. Ensure the backing plate or platen is clean and flat before mounting the disc to avoid uneven contact. Follow the equipment manufacturer's guidelines for disc mounting, speed settings, and coolant or lubricant use. Wear appropriate PPE including eye protection when operating lapping equipment.
