Chestnut Mandrels are available separately or come as part of the Buffing Wheel Kit.
 
Chestnut Mandrels are made in the UK and are zinc plated for maximum protection. Due to the limitations of plating a blind hole care should be taken to ensure the tapped thread of the large mandrel stays as dry as possible.
 
The small mandrel is designed to be held in a jacobs chuck or similar and is especially suited to use with the smaller 4 inch wheels and the Dome Buffs. It can also be used in a drill for careful freehand polishing.
