3M 7010308018 Flexible Diamond Psa Sheet 2x40 in M74 Micron

Product Description

The 3M 7010308018 is a flexible diamond abrasive sheet with a PSA (pressure-sensitive adhesive) backing designed for precision finishing on hard-to-grind materials. The sheet measures 2 inches x 40 inches and is built on a 2MM foam substrate that conforms to contoured and irregular surfaces. M74 micron-graded diamonds are anchored to the backing through a metal-plated bond, delivering consistent cut rates alongside a refined surface finish. This combination of conformability and abrasive precision makes it well suited for surface preparation and finishing tasks in fabrication, tool sharpening, and maintenance environments.

This abrasive sheet is used across a range of demanding applications including work on stone, glass, ceramic, hardened metal, carbide, and composite materials. The PSA backing allows for quick mounting to flat or contoured platens and backing pads without additional adhesives. It is commonly used in fabrication shops, lapidary work, precision grinding operations, and maintenance environments where conventional abrasives lose cut rates or leave a poor surface finish on hard substrates.

Key Features

• M74 micron-graded diamond abrasive for consistent, controlled material removal
• Metal-plated bond securely anchors diamonds to the PSA backing for extended abrasive life
• 2MM foam substrate conforms to irregular and contoured surfaces
• PSA backing mounts quickly to platens and backing pads without additional adhesives
• Effective on stone, glass, ceramic, metal, carbide, and composites
• Delivers refined surface finish without sacrificing cut rates

Compatibility

Designed for use on hard-to-grind materials including stone, glass, ceramic, hardened metal, carbide, and composites. Suitable for PSA-compatible backing pads and platens in precision finishing and grinding applications.

Installation Notes

Application of this sheet is typically performed by skilled tradespeople, fabricators, or tooling technicians familiar with abrasive finishing operations. Ensure the mounting surface or platen is clean and free of debris before applying the PSA backing. Secure full contact across the sheet surface to prevent lifting during use. Follow applicable shop safety protocols including appropriate PPE for grinding and finishing operations on hard materials.
