3M 22970, Disc Holder Adapter 9, 5/8-11 External 3/8-24 Internal, 7000046093

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.
