3M 7100033114 Diamond Lapping Film 30.0 Micron 1inx50ft

Product Description

The 3M 7100033114 is a diamond lapping film designed for precision surface finishing of extremely hard materials. The film consists of precisely graded diamond abrasive particles coated onto a dimensionally stable polyester backing. It delivers a consistent, repeatable finish across the full length of the roll, making it a reliable choice for tight-tolerance lapping applications. At 30.0 micron grade, this roll is suited for stock removal and surface conditioning stages where controlled cutting action is required before progressing to finer grits. Licensed tradespeople and precision fabricators working with ceramics, carbide, hardened steel, optical components, and fiber optic connectors commonly reach for this product.

This lapping film is used in applications that demand flat, uniform surface finishes on hard substrates. The 1-inch width and 50-foot roll length make it compatible with belt-style lapping fixtures, hand lapping blocks, and automated precision finishing equipment. It is appropriate for both shop and field use where a controlled abrasive process is needed on materials that defeat conventional aluminum oxide or silicon carbide abrasives. The 30.0 micron grade is typically used in early-stage lapping sequences before stepping down through finer micron grades to achieve a final surface specification.

Key Features

• Effective on ceramics, carbide, hardened steel, optical components, and fiber optic end faces
• Available across a broad grade range from 0.10 to 30.0 micron for full lapping sequences

Compatibility

Designed for use with standard 1-inch lapping film fixtures, belt lapping tools, and hand lapping blocks that accept roll-format abrasive film. No specific compatible model numbers were provided in the product data.

Installation Notes

This product is handled and applied by precision machinists, optical technicians, and trade professionals performing surface finishing work. Secure the film flat against the lapping plate or fixture before applying pressure to avoid wrinkles that could cause uneven stock removal. Keep the film and workpiece free of contamination from coarser abrasive particles when transitioning between micron grades. Follow shop safety practices for abrasive materials, including eye protection when dry lapping.
