This introductory kit includes 10 of the new RP 9000 stainless steel corks. They have the same 3/8" 16tpi stud and the top diameter is the same as all of my other stoppers.
The kit also comes with a mandrel of your choice, and a 21/64" and 5/16" stub drill bits (the stub bit prevents wander if it hits hard grain) and a draw bar of choice. The 10" is for
a mini lathe and a full size lathe takes the 16" bar. *Note: if you do not need a draw bar, put a note to add an additional stainless cork.
