3M 7010360241 Diamond Lapping Film 661X 15.0 Micron Roll

Product Description

The 3M 7010360241 is a diamond lapping film roll designed for precision finishing of extremely hard materials. The 661X series uses precisely graded diamond abrasive particles coated onto a dimensionally stable polyester film backing. At 15.0 microns, this grade is suited for intermediate-stage lapping and finishing where a consistent, repeatable surface finish is required across the entire workpiece. The roll format measures 0.50 inches wide by 50 feet long, wound on a 1-inch core for use with compatible lapping fixtures and film-feed systems. Technicians and precision fabricators working with ceramics, carbides, optical components, fiber optic connectors, and hardened tool steels rely on this product for controlled material removal.

This lapping film is used in precision manufacturing, optical fiber termination, and toolroom finishing applications. The 15.0 micron grade is typically applied mid-sequence in a multi-step lapping process, between coarser stock-removal steps and finer polishing stages. It is well suited for bench lapping, fiber optic polishing fixtures, and automated film-feed systems in production environments. The roll format supports continuous-feed operations where consistent abrasive performance across the full length of the roll is critical.

Key Features

• Precisely graded 15.0 micron diamond abrasive particles for consistent, repeatable surface finishes
• Polyester film backing provides dimensional stability during lapping and polishing
• 0.50-inch width by 50-foot roll length suits continuous-feed and fixture-based lapping systems
• 1-inch core compatible with standard film-feed fixtures and lapping machines
• Diamond abrasive excels on extremely hard materials including ceramics, carbides, and hardened steels
• Part of the 661X series, available in grades from 0.10 to 30.0 micron for multi-step finishing sequences

Compatibility

Designed for use with lapping fixtures, fiber optic polishing machines, and film-feed systems that accept 0.50-inch wide lapping film on a 1-inch core. Suitable for precision finishing of hard materials across optical, toolroom, and industrial manufacturing applications.

Installation Notes

Load the film roll into a compatible lapping fixture or film-feed system according to the equipment manufacturer's instructions. Ensure the work surface and fixture are free of contaminants before beginning the lapping sequence, as debris can cause scratching at fine micron grades. When performing multi-step finishing, progress through grades in sequence from coarser to finer to achieve the target surface finish. Follow all applicable shop safety procedures, including appropriate eye protection, when handling abrasive films and workpieces.
