3M 7000044818 Abrasive Disc 10 in Aluminum Oxide Psa

Product Description

The 3M 7000044818 is a 10-inch diameter abrasive disc designed for precision finishing applications where consistent cut rate and surface quality are required. The disc features aluminum oxide mineral coated onto a 3 mil polyester film backing, bonded with a durable resin system. A pressure-sensitive adhesive (PSA) backing allows for fast, secure mounting to compatible backup pads. Available in grades ranging from 0.05 to 60.0 micron, this disc is suited for trades and technicians who demand repeatable results across multiple finishing operations. The harder resin system and tight particle distribution extend disc life and help maintain a consistent finish throughout the service life of each disc.

Primary applications include fiber optic connector finishing and roll superfinishing. The disc is well suited for precision manufacturing environments, optical fiber service operations, and surface finishing shops requiring controlled micro-abrasion. The range of available micron grades makes it adaptable across multiple stages of a finishing sequence, from material removal to fine polishing. Technicians working in telecom, aerospace, and industrial production settings will find this disc appropriate for both bench and fixture-mounted applications.

Key Features

• Aluminum oxide mineral on 3 mil polyester film for dimensional stability
• PSA backing for quick mounting and secure adhesion to backup pads
• Tight particle distribution for consistent cut rate and finish quality
• Harder resin system compared to 261X series for extended disc life
• Available in grades from 0.05 to 60.0 micron to cover multiple finishing stages
• Also available in sheets and rolls for varied workflow needs

Compatibility

Designed for use as a PSA-mounted abrasive disc on compatible 10-inch backup pads used in fiber optic finishing and roll superfinishing applications.

Installation Notes

Power down or de-energize any equipment before mounting or removing abrasive discs. Ensure the backup pad surface is clean and free of debris before pressing the PSA-backed disc into place to achieve full adhesion. Alignment of the disc to the pad center will help prevent uneven wear and inconsistent finish results. Follow all applicable facility safety protocols and equipment manufacturer guidelines when operating finishing machinery.
