3M 7000044734 Diamond Lapping Film 6 Micron 6x6 in Sheet

Product Description

The 3M 7000044734 is a diamond lapping film sheet designed for precision surface finishing of extremely hard materials. Precisely graded diamond abrasive particles are coated onto a dimensionally stable polyester film substrate, delivering a consistent, repeatable finish with each pass. Rated at 6.0 micron particle size, this sheet is suited for fine lapping and polishing operations where surface geometry and finish quality must meet tight tolerances. Each sheet measures 6 inches x 6 inches and is sold individually. Machinists, toolmakers, optical technicians, and fiber optic splice technicians commonly use this product for controlled material removal and surface conditioning.

This lapping film is used in applications requiring precise stock removal and high-quality surface finishes on hard substrates including carbide, ceramics, hardened steel, glass, and optical components. The 6.0 micron grade positions it in the fine finishing range, appropriate for intermediate lapping steps or final finishing depending on the base material and target surface roughness. It is well suited for bench lapping, fixture-mounted lapping, and hand polishing in both shop and field environments.

Key Features

• 6.0 micron diamond abrasive grade for fine, controlled material removal
• Precisely graded diamond particles ensure consistent cut rate and uniform finish
• Polyester film backing provides dimensional stability and conforms to flat lapping surfaces
• 6 inches x 6 inches sheet format for versatile bench and fixture use
• Effective on extremely hard materials including carbide, ceramics, and glass

Compatibility

Designed for use on extremely hard materials such as carbide, ceramics, hardened steel, glass, and optical components requiring fine lapping and polishing. Part of the 3M Diamond Lapping Film 661X series, available in grades ranging from 0.10 to 30.0 micron.

Installation Notes

Lapping film is typically used by machinists, optical technicians, or toolroom professionals on flat glass plates, granite surface plates, or dedicated lapping fixtures. Secure or hold the sheet firmly against the lapping surface before use to prevent slipping. No power tools or special codes apply to hand lapping; however, follow shop safety procedures for handling sharp or fragile workpieces. Discard the sheet when abrasive performance noticeably degrades to maintain finish consistency.
