The mandrels are precision-made from high-grade stainless steel, ensuring a high-quality finish and precise dimensions.
They are compatible with both NT-3000 and NT-1000 neck turning tools, as well as older models, and are designed to size the case perfectly for easier and more accurate neck turning.
Expander mandrels are slightly larger than turning mandrels and can be used to neck up cases to the next caliber, enhancing the versatility of the reloading process.
