These Mandrels are available separately or come as part of the Buffing Wheel Kit.
Both 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 large mandrel is designed to be held in a lathe chuck. It is 25mm in diameter at its widest part, stepped to 18mm with an undercut for smaller chucks. It can be held on either, both will still give plenty of clearance from the chuck.
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.
