The Sinclair TiN Turning Mandrels offer increased abrasion resistance and tool life up to 10 times longer than standard steel mandrels due to their Titanium Nitride coating.
These mandrels are designed with a diameter 0.002" under bullet diameter for precise alignment during neck turning or setting neck tension.
They are specifically made for 25 Caliber (0.255") applications and provide added lubricity for smoother operation.
