This bottle stopper mandrel has small threads that fit the following stoppers:
- Cork & Chrome Wine Bottle Stopper
- Tear Drop Wine Bottle Stopper with Standard Stud
- Black Titanium Presentation Bottle Stopper
- Titanium Gold Presentation Bottle Stopper
I believe the threads are 1/4-20 and uses a 6mm drill bit.
Hold the mandrel in a drill chuck.
