The Sinclair TiN Turning Mandrels are a great option for those who want increased resistance to abrasion over our Stainless Steel Mandrels, but don't feel the need to upgrade to our Carbide Mandrels. The Titanium Nitride coating process adds increased lubricity, reduces wear due to abrasion and increases tool life up to 10 times over our standard steel mandrels. Turning mandrels are made to 0.002" under bullet diameter. Originally designed to be used to align the case during neck turning, these Mandrels can also be used to set neck tension.
