Sinclair neck turning tool mandrels are made from high grade stainless steel on Precision turning centers. The shape, finish, and size are the result of years of use and experimentation by many hand loaders. All of their mandrels fit both models of their current neck turning tools and most of their older model neck turning tools.

Sinclair neck turning tool mandrels measure approximately about .002 inch less than the bullet diameter for the calibre. Their expander mandrels are made .001 inch larger than the turning mandrels. Using an expander mandrel prior to neck turning sizes the case to fit the neck turning mandrels perfectly. This correct fit makes the turning process more precise and much easier. Any of the mandrels can be used to expand  cases up to the next calibre when used with the Sinclair NT-EXP (Expander Body).
