3M 7000044816 Abrasive Disc 10 in Aluminum Oxide Psa

Product Description

The 3M 7000044816 is a 10-inch diameter precision abrasive disc engineered for controlled, repeatable surface finishing in demanding trade and industrial applications. Aluminum oxide mineral is coated onto a 3 mil polyester film substrate and bonded with a durable resin system. The disc features a pressure-sensitive adhesive (PSA) backing for fast, secure mounting to compatible backup pads. Available in grades ranging from 0.05 to 60.0 micron, this disc delivers consistent cut rate, finish quality, and service life across its full grade range. The harder resin system compared to the 261X series provides tighter particle distribution and longer-lasting performance under sustained use.

This disc is suited for precision finishing work in fiber optic connector termination and roll superfinishing operations. The PSA backing and polyester film construction make it a practical choice for technicians and machinists who require dimensional consistency and repeatable surface quality. It is sold individually and is appropriate for both production-line environments and controlled bench finishing setups where micron-level surface control is required.

Key Features

• PSA backing for secure, tool-free mounting to compatible backup pads
• Tight particle size distribution for consistent finish and cut rate
• Harder resin system than 261X series for extended service life
• Aluminum oxide mineral on 3 mil polyester film for dimensional stability
• Available in grades from 0.05 to 60.0 micron
• Suitable for fiber optic finishing and roll superfinishing applications

Compatibility

Designed for use with PSA-compatible backup pads sized for 10-inch diameter abrasive discs in precision finishing equipment.

Installation Notes

Power down and lock out all rotating equipment before mounting or removing abrasive discs. Peel the PSA liner and align the disc squarely to the backup pad surface before pressing firmly to seat the adhesive. Inspect the disc for tears, delamination, or contamination before each use and replace if any defects are present. Follow applicable workplace safety standards and equipment manufacturer guidelines for maximum RPM and operating conditions.
