PMA Carbide Neck Turning Mandrels (PCM-10xx)

When treated and maintained properly, stainless steel mandrels (specifically 17-4 stainless) will retain their size and finish for years under normal use, satisfying the needs of most reloaders. That being said, carbide offers several advantages over steel and stainless steel when making any tooling. Neck turning mandrels are no different.

  • Dimensional Stability - Carbide maintains its dimensions indefinitely during heating and cooling. This eliminates the need to allow the mandrel time to cool every few cases.


  • Coefficient of Friction and Wear-Resistance - Carbide exhibits a low coefficient of friction value as compared to all steels and wears up to 100 times longer. This reduces (does not eliminate) the amount of lubricant required.


  • Galling - Carbide has exceptional resistance to galling and welding at the surface. This basically eliminates the chance of getting a case stuck on a mandrel due to insufficient lubrication.


All of these advantages add up to a mandrel that does not wear out or change size due to friction and heat; and requires less lubrication than stainless mandrels.

    Easy to insert and correctly sized for even cuts

    I started with another manufacturers mandrels on another system, theirs was somewhat undersized so the necks wobbled. The PMA mandrel accepts tight fitting necks with lube and in combination with their cutter get me runout consistently sub 0.001 when using decent brass.
