Self Tapping Bottle Stopper Mandrel

The First Self-Tapping bottle stopper chuck! Simply drill a 5/16” hole in your bottle stopper blank and screw the blank into the mandrel. When finished turning, hold the mandrel by placing a ¼” screw driver into the spanner hole and unscrew your turned bottle stopper.

This Mandrel can be chucked into a 3 or 4 jawed chuck or it can be placed into a Morse Taper # 2 head stock – (the back end of the mandrel is threaded for a 1/4-20 draw bar)
