3M 7000045609 Abrasive Disc 8 in Aluminum Oxide Psa

Product Description

The 3M 7000045609 is an 8-inch diameter coated abrasive disc built for precision microfinishing applications. The disc uses aluminum oxide mineral on a 3 mil polyester film backing with a durable resin system and a pressure-sensitive adhesive (PSA) base for fast, secure mounting. The harder resin system delivers a consistent cut rate, finish quality, and disc life across a range of micron grades. Available grades span 0.05 to 60.0 micron, giving technicians fine control over stock removal and surface finish. Each disc is sold individually and weighs 0.02 pounds.

This disc is designed for applications requiring tight tolerances and repeatable surface finishes. Primary uses include fiber optic connector end-face finishing and roll superfinishing operations. The tight particle distribution ensures uniform material removal and reduces the risk of surface defects in precision finishing workflows. It is commonly specified in optical, electronics, and industrial manufacturing environments where surface quality is critical.

Key Features

• PSA backing for quick, secure disc mounting without adhesive transfer tools
• Tight particle distribution for uniform cut and consistent surface finish
• Harder resin system compared to 261X film for extended disc life
• Available in grades from 0.05 to 60.0 micron to match finishing requirements
• Aluminum oxide mineral on 3 mil polyester film for dimensional stability
• Available in disc, sheet, and roll formats for flexible workflow integration

Compatibility

Designed for use in fiber optic finishing and roll superfinishing applications where PSA-backed 8-inch abrasive discs are required.

Installation Notes

This disc is typically applied by trained technicians or machine operators in precision finishing environments. Before mounting, ensure the backing plate or platen is clean and free of debris to guarantee full PSA adhesion. Press the disc firmly onto the platen and allow brief contact pressure before beginning the finishing pass. Replace the disc when cut rate or finish quality degrades to maintain process consistency.
