3M 7000044752 Diamond Lapping Film 15.0 Micron 2x50 Ft Roll

Product Description

The 3M 7000044752 is a diamond lapping film designed for precision surface finishing on extremely hard materials. It features precisely graded diamond abrasive particles coated onto a dimensionally stable polyester film backing, delivering a consistent and repeatable finish across the full length of the roll. At 15.0 micron grade, this film is suited for intermediate lapping and stock removal stages where controlled surface finish is critical. The roll format measures 2 inches wide by 50 feet long, wound on a 3-inch core for compatibility with standard dispensing equipment. Technicians in fiber optic, tooling, ceramic, and hard-metal finishing applications rely on this product for tight surface finish tolerances.

This lapping film is used in applications requiring controlled material removal on hard substrates such as carbide, ceramic, glass, hardened steel, and optical components. The roll format suits both bench-mounted lapping fixtures and hand-lapping operations. It is appropriate for production environments where finish consistency from part to part is a process requirement. Available in a range of grades from 0.10 to 30.0 micron, this 15.0 micron version fits mid-stage lapping sequences before transitioning to finer grades for final surface conditioning.

Key Features

• 15.0 micron diamond abrasive grade for intermediate lapping and controlled stock removal
• Precisely graded diamond particles ensure a consistent, repeatable surface finish
• Polyester film backing provides dimensional stability during lapping operations
• 2-inch width by 50-foot length roll on a 3-inch core suits standard dispensing setups
• Effective on extremely hard materials including carbide, ceramic, and hardened steel
• Part of a multi-grade product line spanning 0.10 to 30.0 micron for full lapping sequences

Compatibility

Designed for use with standard lapping film dispensing fixtures and hand-lapping setups that accept 2-inch wide film rolls on a 3-inch core. Suitable for finishing operations on hard substrates where conventional abrasives do not provide adequate cut rate or finish consistency.

Installation Notes

Lapping film should be handled by the edges to avoid contaminating the abrasive surface with oils or debris. Ensure the work surface and fixturing are clean before loading a new roll to prevent cross-contamination between grades. When working through a multi-step lapping sequence, complete all passes at the current grade before moving to a finer film. Follow applicable facility safety guidelines for abrasive operations, including eye protection and proper ventilation when working with fine particulate-generating processes.
