3M 7010291299 Psa Disc Holder 3 Inch 1/4 Inch Shank

Product Description

The 3M 7010291299 is a PSA disc holder designed to mount pressure-sensitive adhesive abrasive discs onto pneumatic and electric sanders equipped with a 1/4 inch collet chuck. The holder features a face diameter that is intentionally smaller than the disc size, which simplifies centering the disc during installation and makes disc removal faster between jobs. The compact design allows technicians to reach confined or irregular surfaces where standard backing plates cannot maneuver. This holder is a straightforward mechanical accessory used by metalworkers, auto body technicians, fabricators, and maintenance trades working with abrasive grinding and finishing tasks.

This disc holder is suited for use in production grinding, surface prep, and finishing applications where PSA-backed abrasive discs are the standard media. The 1/4 inch shank fits collet chucks commonly found on die grinders, allowing it to be used in tight spots, corners, and recessed areas that are difficult to access with larger sanding tools. It is sold individually and is compatible with 3 inch PSA abrasive discs.

Installation Notes

Installation is performed by securing the 1/4 inch shank into the collet chuck of the host tool and tightening per the tool manufacturer's specifications. Always power down and disconnect the air supply or electrical source from the grinder before attaching or removing the disc holder. Apply the PSA disc to the holder face on a clean, dry surface to ensure proper adhesion before use. Follow applicable workplace safety standards for abrasive tool operation, including use of appropriate eye and face protection.
