3M 7100048137 Diamond Lapping Film Psa Disc 1.0 Micron

Product Description

The 3M 7100048137 is a pressure-sensitive adhesive (PSA) diamond lapping film disc designed for precision surface finishing of extremely hard materials. Built on a dimensionally stable polyester film base, it carries precisely graded diamond abrasive particles that deliver consistent, repeatable results across multiple passes. The disc measures 2 inches in diameter and is rated at 1.0 micron particle size, placing it in the fine-finishing range. It is used by technicians and machinists who require tight surface-finish tolerances on hard substrates such as ceramics, carbide, optical components, and hardened tool steel.

This disc is suited for bench lapping, fixture-mounted lapping, and handheld finishing operations where a PSA backing is needed for quick mounting to a flat or backed platen. The 1.0 micron grade is appropriate for final or near-final finishing stages where surface roughness must be minimized without aggressive material removal. Trades and industries that commonly use this product include optical fabrication, precision machining, fiber-optic connector polishing, and tool and die work. The PSA backing simplifies disc changes and reduces setup time compared to non-adhesive film products.

Key Features

• Precisely graded 1.0 micron diamond abrasive particles for fine, repeatable surface finishes
• PSA backing for fast, secure mounting to compatible platens or backing pads
• Polyester film base provides dimensional stability under lapping pressure
• 2-inch disc diameter fits standard lapping fixtures and handheld backing plates
• Suitable for extremely hard materials including ceramics, carbide, and hardened metals
• Available across a broad grade range from 0.10 to 30.0 micron for multi-stage finishing sequences

Compatibility

Designed for use with 2-inch PSA-compatible lapping platens, backing pads, and fixtures used in precision surface-finishing operations on hard substrates.

Installation Notes

Clean the platen or backing pad surface thoroughly before applying the PSA disc to ensure full adhesion and prevent disc slippage during use. Apply firm, even pressure across the disc face when mounting to eliminate air pockets. Follow all facility safety protocols for handling fine abrasive materials, including eye protection. Dispose of used discs according to applicable workplace safety guidelines.
