Added Adaptability
The 3M Disc Holder Adapter is a simple way to equip your power tools and sanders to use larger 5/8-11 threaded disc holders or quick change (integral 5/8-11 hub) abrasive products. The adapter conveniently screws onto the tool spindle and converts the smaller external threaded shaft to a 5/8-11 external threaded shaft. This allows you to use an even larger array of discs without needing to buy a completely new tool.

Our 3M Disc Holder Adapter is used to attach abrasive disc holders with 5/8-11 center holes onto power tools equipped with smaller spindles. The interior threads screw onto the shaft of a sander or other power tool, effectively increasing the size of the tool shaft to accommodate a product with 5/8-11 disc holders.
