3M 7000045779 Psa Disc Holder 2 Inch 1/4 Inch Shank

Product Description

The 3M 7000045779 is a PSA (pressure-sensitive adhesive) disc holder designed to support abrasive discs during grinding in confined or hard-to-reach areas. The holder features a face diameter intentionally sized smaller than the disc it supports, making disc centering and removal straightforward during use. The 1/4 inch shank fits standard 1/4 inch collet rotary and die grinder tools. At 0.06 pounds, it is a lightweight accessory suited for frequent swaps between abrasive discs on the job.

This disc holder is used in metal fabrication, automotive bodywork, welding prep, and general grinding applications where access is limited. The PSA backing system allows the abrasive disc to mount securely and release cleanly, reducing downtime between disc changes. It is typically used by metalworkers, auto body technicians, pipefitters, and maintenance trades who rely on die grinders for surface preparation in tight spaces.

Key Features

• Face diameter smaller than disc size for easier centering and disc removal
• Accepts 1/4 inch shank rotary and die grinder tools
• Compatible with PSA-backed abrasive discs
• Lightweight at 0.06 pounds for reduced operator fatigue

Compatibility

Installation Notes

Insert the 1/4 inch shank into the collet of the rotary tool or die grinder and tighten securely before attaching any abrasive disc. Ensure the tool is powered off and disconnected from any power source before mounting or removing the disc holder. Follow the tool and abrasive manufacturer guidelines for maximum RPM ratings to avoid disc separation during use. Inspect the PSA surface before each disc application to confirm it is clean and free of debris.
