Square Forming Mandrels

Fashioned from steel, each mandrel tapers from 18 mm to 6 mm and is 12" long. Both mandrels are square in profile: item 320-618 has sharp corners and item 320-619 has cut corners. Each mandrel is provided with a steel adapter that screws into the handle of the mandrel which allows the user to install the mandrel into a bench vise or into a hole you've created in your work bench. Or, you can install these mandrels into our Mandrel Vise. Either arrangement permits hands-free work.
