3M 7010360187 Diamond Lapping Film 6.0 Micron Sheet

Product Description

The 3M 7010360187 is a diamond lapping film sheet used 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, repeatable finish with each pass. The sheet measures 8.50 inches x 8.50 inches and carries a 6.0 micron grade, placing it in the fine-finishing range. Technicians and machinists use it where tight surface tolerances are required and conventional abrasives fall short. The polyester backing resists tearing and maintains flatness during use, which is critical for achieving accurate, predictable results on hard substrates.

This lapping film is suited for precision finishing applications across optical, ceramic, carbide, and hardened metal components. Common use cases include fiber optic connector end-face polishing, ceramic ferrule lapping, carbide tooling touch-up, and precision gauge surface work. It is used in both shop and field environments by tool and die technicians, optical fiber technicians, and precision instrument specialists who require repeatable stock removal at fine micron grades.

Key Features

• 6.0 micron diamond abrasive grade for fine surface finishing
• Precisely graded particles provide consistent, repeatable finish results
• Polyester film backing maintains dimensional stability under load
• 8.50 inch x 8.50 inch sheet size accommodates a range of hand-lapping fixtures and platens
• Effective on extremely hard materials including ceramics, carbides, and hardened metals

Compatibility

Designed as an OEM-style replacement lapping film sheet for precision finishing applications requiring a 6.0 micron diamond abrasive on a polyester film backing.

Installation Notes

Lapping film is typically used by precision technicians and optical fiber specialists. Secure the sheet flat against a lapping plate or fixture before use to prevent slipping and uneven stock removal. Keep the work surface and film clean of debris between passes. Follow applicable workplace safety guidelines for handling diamond abrasive materials.
