3M 7000000316 Diamond Lapping Film 9.0 Micron Roll

Product Description

The 3M 7000000316 is a diamond lapping film designed for precision surface finishing on extremely hard materials. Precisely graded diamond particles are coated onto a durable polyester film substrate, delivering a consistent, repeatable finish across the full length of the roll. The 9.0 micron grade makes this film suitable for intermediate lapping and stock removal stages where controlled abrasion is required. It is used by machinists, optical technicians, fiber optic technicians, and other precision trade professionals who require tight surface finish tolerances on hard substrates.

This diamond lapping film is used in applications involving ceramics, carbide, hardened steel, glass, sapphire, and similar hard materials that conventional abrasives cannot finish effectively. The roll format measures 4 inches wide by 150 feet long with a 3-inch core, making it compatible with standard lapping film dispensing equipment and machine lapping setups. It is suitable for both automated and hand lapping operations in manufacturing, maintenance, and repair environments.

Key Features

• 9.0 micron precisely graded diamond abrasive for controlled, repeatable stock removal
• Diamond particles bonded to polyester film for consistent cut rate and finish quality
• Roll format: 4 inches wide by 150 feet long on a 3-inch core
• Effective on extremely hard materials including ceramics, carbide, and hardened steel
• Available in grades ranging from 0.10 to 30.0 micron for multi-stage lapping sequences

Compatibility

Designed for use with standard lapping film dispensing and machine lapping equipment that accepts 4-inch wide rolls on a 3-inch core. Suitable for multi-stage finishing sequences when used alongside other micron grades in the 3M Diamond Lapping Film 661X series.

Installation Notes

Load the roll onto compatible lapping equipment following the equipment manufacturer's guidelines. Ensure the work surface and film are clean and free of debris before starting to avoid scratching caused by contamination. Use appropriate personal protective equipment when handling diamond abrasive films, as edges and particles can cause cuts and skin irritation. Follow applicable workplace safety standards for abrasive material handling.
