3M 7000044827 Diamond Lapping Film 1.0 Micron Sheet

Product Description

The 3M 7000044827 is a diamond lapping film sheet engineered for precision surface finishing on extremely hard materials. Precisely graded diamond abrasive particles are electrostatically coated onto a dimensionally stable polyester film backing, producing a consistent, repeatable cut and finish with each pass. At a 1.0 micron grade, this sheet is suited for fine finishing stages where surface geometry and smoothness tolerances are tight. Each sheet measures 9 inches x 11 inches and weighs approximately 0.06 pounds. Technicians and tradespeople working with carbide tooling, ceramic components, optical fiber connectors, or similarly hard substrates rely on this film where conventional abrasives cannot hold the required geometry.

This lapping film is used in precision finishing and refurbishing applications across industries including fiber optic termination, toolroom work, and hard-materials surface preparation. The 1.0 micron grade is typically applied in intermediate-to-final finishing sequences following coarser diamond or abrasive film stages. It is suitable for flat lapping, cylindrical finishing, and backing-plate work on glass, ceramics, carbide, and hardened steel. Minimum order quantity is 10 sheets per order.

Key Features

• 1.0 micron precisely graded diamond abrasive for fine, controlled material removal
• Diamond particles coated on a dimensionally stable polyester film backing
• Consistent, repeatable finish across successive passes on hard substrates
• Sheet size of 9 inches x 11 inches fits standard lapping fixtures and backing plates
• Suitable for glass, ceramics, carbide, hardened steel, and similar hard materials
• Available in a range of grades from 0.10 to 30.0 micron for multi-stage finishing sequences

Compatibility

Designed for use on extremely hard materials including carbide, ceramics, glass, and hardened steel; compatible with standard flat lapping plates, backing films, and fiber optic polishing fixtures that accept 9 inches x 11 inches sheet stock.

Installation Notes

This lapping film is typically applied by skilled technicians or toolroom machinists familiar with precision abrasive finishing sequences. Ensure the backing plate or lapping fixture surface is clean and free of debris before applying the film to avoid scoring or uneven cut. Use consistent, controlled pressure and motion patterns to achieve repeatable results across the work surface. Follow all applicable workplace safety guidelines for handling abrasive films, including eye and hand protection.
