3M 7010307689 Diamond Lapping Film 15.0 Micron Roll

Product Description

The 3M 7010307689 is a diamond lapping film supplied in roll form, designed for precision surface finishing of extremely hard materials. Precisely graded diamond abrasive particles are coated onto a dimensionally stable polyester film backing, delivering a consistent and repeatable surface finish across the full length of the roll. At 15.0 micron grade, this film is suited for intermediate lapping and polishing stages where controlled material removal and fine surface refinement are required. The 0.375-inch width and 50-foot length make it practical for use on fiber optic connectors, ceramic components, carbide tooling, and other hard substrates encountered in precision manufacturing and repair environments.

This lapping film is used in applications where conventional abrasive films lack the hardness or consistency needed to work efficiently on ceramics, carbide, glass, and similarly hard substrates. The roll format supports use with automated lapping fixtures, hand lapping tools, and custom jigs in production or field service settings. It is commonly specified by technicians and engineers performing fiber optic connector end-face finishing, precision tooling reconditioning, and fine optical or mechanical surface preparation.

Key Features

• 15.0 micron diamond abrasive grade for intermediate lapping and surface refinement
• Precisely graded diamond particles ensure a consistent, repeatable finish
• Polyester film backing provides dimensional stability under lapping loads
• Roll format: 0.375 inches wide by 50 feet long for continuous use
• Effective on extremely hard materials including ceramics, carbide, and glass
• Available in multiple grades from 0.10 to 30.0 micron for full finishing sequences

Compatibility

Designed for use on extremely hard materials requiring precision surface finishing; suitable for integration with standard lapping fixtures and hand lapping tools that accept 0.375-inch wide film stock.

Installation Notes

This film is installed and used by precision technicians and manufacturing professionals in controlled surface finishing operations. Secure the film properly in the lapping fixture or tool before beginning to prevent slippage and uneven wear. Avoid folding or creasing the film, as this can introduce surface defects into the finished workpiece. Follow the material and equipment manufacturer guidelines for lapping fluid use, pressure, and stroke pattern.
