3M Bristle Disc Mandrel is a tool attachment that holds a small abrasive bristle disc (sold separately). Together, the mandrel and disc enable the user to clean, blend, or finish hard-to-reach areas of a work piece, such as inside corners, complex angles and curves. The mandrel attaches to a rotary tool such as a die grinder or drill.
From the Manufacturer
The 3M™ Bristle Disc Mandrel 27680 is used on a bristle disc that is 1" or smaller in diameter with a 1/16" center hole, for attachment to a 3/32" drill or collet chuck. The two-piece mandrel has a bolt that is inserted through the center hole of the bristle disc and then tightened into a threaded spindle. The spindle can then be inserted in a 3/32" collet chuck or drill. Max RPM is 30,000.

Works perfectly- great to have extra mandrels to make swapping polishing discs so much faster and easier

These wrk perfectly with all the 3M bristle disks that I use if you stop stacking disks at 5. Since 3M say always stack 3 they are good for 3, 4, or 5. If you want to stack more than 5 keep looking. They are much better constructed than the mandrels that come with some low priced diamond wheels on sale on Amazon
