3M 7010328363 Psa Disc Holder 0.5 in 0.25 in Shank

Product Description

The 3M 7010328363 is a PSA (pressure-sensitive adhesive) disc holder designed to support abrasive discs during grinding operations in hard-to-reach areas. The holder features a face diameter smaller than the mounted disc, which makes centering the disc easier and simplifies disc removal after use. It accepts a 0.25 inch shank and is compatible with standard 0.25 inch center-hole shank grinding tools. Weighing only 0.03 pounds, this lightweight holder is built for precision access work where larger backing pads cannot fit. It is sold individually.

This disc holder is suited for use in fabrication, metalworking, maintenance, and repair applications where standard grinding pads cannot access tight geometry. Typical use cases include weld dressing in confined spaces, surface preparation inside tubing, and detail grinding on structural components. The reduced-diameter face allows the attached abrasive disc to overhang the holder, giving the technician better control during edge and contour work. It is commonly used by metalworkers, maintenance mechanics, and fabricators working with angle grinders and die grinders.

Installation Notes

Installation is performed by threading the 0.25 inch shank into a compatible die grinder or rotary tool chuck and tightening per the tool manufacturer's specifications. Always power down and unplug or de-energize the tool before mounting or removing the disc holder or any abrasive disc. Inspect the PSA disc for damage or lifting edges before each use. Follow applicable workplace safety standards and wear appropriate PPE including eye protection when operating grinding equipment.
