3M 7010328364 Psa Disc Holder 1.5 in 0.25 in Shank

Product Description

The 3M 7010328364 is a PSA (pressure-sensitive adhesive) disc holder designed to support abrasive grinding discs during use in hard-to-reach areas. The holder features a face diameter smaller than the disc it carries, which makes centering and removing discs faster and more accurate on the job. It accepts grinding tools with a 1/4-inch center hole shank, making it compatible with standard rotary tools and die grinders commonly used in metal fabrication, auto body, and maintenance work. The disc face diameter is 1.5 inches. This holder is sold individually and is a practical consumable for any tech running PSA-backed abrasive discs.

This disc holder is suited for use in tight clearance grinding applications where a standard-size backing pad would not fit or would obstruct the work area. Typical use cases include weld removal, surface prep, and deburring in confined spaces such as automotive panels, HVAC ductwork seams, and pipe welds. It is commonly used by fabricators, auto body technicians, pipefitters, and maintenance mechanics who need reliable disc retention at speed.

Installation Notes

Installation is performed by threading the 1/4-inch shank into the collet of a compatible rotary tool or die grinder and tightening per the tool manufacturer's specifications. Ensure the tool is fully powered off and unplugged or the air supply is disconnected before attaching or removing the disc holder. Press the PSA disc firmly onto the holder face to ensure full adhesive contact before operating. Inspect the disc and holder for wear or damage before each use.
