Their Carbide turning mandrels are precision ground from solid carbide stock, which yields even closer tolerances. All Carbide mandrels are ground to . 002" under bullet diameter. Adjustments on the Sinclair Premium Neck Turning tool will be more consistent with carbide mandrels due to the tighter tolerances of the mandrels.
