The Sinclair TiN Expander Mandrels offer increased abrasion resistance and lubricity compared to standard steel mandrels due to their Titanium Nitride coating.
These mandrels are designed to be 0.001" under bullet diameter, making them suitable for expanding the necks of brass prior to neck turning or for setting neck tension.
The product is specifically tailored for 6mm caliber with a diameter of 0.242 inches, providing a precise fit for reloading tasks.
