$20.00 with a 5/16″ stub drill bit  ~  $21.60 if purchased separately.

This Niles ™mandrel threads onto the head stock spindle and has the unique tapered flute making it the best self-tapping mandrel on the market.   It has a 3/8″ – 16 tpi threaded stud that works with just about all the stoppers available and numerous other projects: ice cream scoop handles, shaving brushes, pizza cutters, etc.  They have a black oxide coating for rust prevention.  The neck or step below the threaded stud is 13/16″ diameter which matches the tops of all my stoppers.  This mandrel does not use a draw bar.

The 5/16″ stub drill bit is nice because it is so short, it won’t “wander” when it hits the wood grain.  It is the standard size when threading a hole.  If you use exotic hardwoods or acrylics or resins, you may want to purchase the 3/8″ Bottoming tap (picture) which makes the job so quick and easy.

Three sizes available:
1″ x 8 tpi for most mini and midi lathes
1.25″ x 8 tpi for most full size lathes
M33 x 3.5 for the Oneway full-size lathes

Check  Mandrel Comparison if you are not sure which mandrel to purchase: this page explains the differences and usages.

Mandrels come with a thread-protector cap and a nylon washer to be used as a spacer to help keep some wood from locking on too tight when you are turning your project. *note: if the wood does get a death grip and you can’t get the project off the mandrel, put the whole thing in the freezer for 10 – 15 minutes and it will unthread once the metal shrinks.
