3M 7010360186 Diamond Lapping Film 3.0 Micron Sheet

Product Description

The 3M 7010360186 is a diamond lapping film sheet designed for precision surface finishing on extremely hard materials. Precisely graded diamond abrasive particles are coated onto a dimensionally stable polyester film backing, delivering a consistent, repeatable finish with each pass. At 3.0 micron particle size, this sheet produces fine surface finishes suited to applications where tight tolerances and controlled material removal are required. The sheet measures 8.50 inches x 8.50 inches and is sold individually. It is typically used by technicians and machinists performing precision lapping, polishing, or flat-honing operations on hard substrates such as ceramics, carbide, optical components, and fiber optic connectors.

This lapping film is used in precision finishing operations across a range of industries and trade applications. It is well suited to fiber optic termination polishing, tool and die finishing, ceramic component lapping, and flat surface preparation on hard metal parts. The 3.0 micron grade positions it in the fine finishing range, making it appropriate as an intermediate or final polishing step depending on the substrate and required surface quality. Technicians working on optical connectors, precision gauges, or cutting tools will find this grade useful for achieving smooth, consistent surface profiles.

Compatibility

Designed as a precision lapping and polishing sheet for use on extremely hard materials including ceramics, carbide, optical fiber connectors, and similar substrates requiring fine, controlled surface finishing.

Installation Notes

This product is used by machinists, optical technicians, and precision finishing specialists. Secure the lapping film flat against a reference surface or lapping plate before use to ensure even abrasive contact. Always clean the workpiece and film surface of debris between polishing stages to prevent cross-contamination of abrasive grades. Follow applicable workplace safety guidelines for handling fine abrasive materials, including appropriate eye and hand protection.
