Shopsmith mandrel has a 3/8″ x 16 tpi threaded stud with the unique ™tapping flute making it the most efficient mandrel on the market.  It also works with other projects: ice cream scoops, shaving brushes, pizza cutters, etc.  It has a black oxide coating to prevent rust.  The 13/16″ diameter collar is the same size as stopper tops.

Mandrels come with a thread-protector cap and 2 nylon washers to be used as a spacer to help keep some wood from locking on too tight when you are turning your project. *tip: 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.

The shorter stub drill bits won’t “wander” if they hit a tight wood grain.  The 5/16″ is the standard size when threading a 3/8″ hole; the 11/32″ is for dense wood, acrylic and resins.

The bottoming tap cuts threads all the way in unlike regular taps that leave about 1/4″ untapped and it makes threading quick and easy.
