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.

    Carbide Mandrel

    PMA carbide mandrels are worth the added cost. They are more consistent and smoother in my opinion. I only use the carbide mandrels for neck turning now, and I only use PMA neck turning tools now. Excellent products and excellent customer service!

    Outstanding Mandrel

    Posted by Felix A Bustamante on 23rd Nov 2016

    Just got my first Carbide Mandrel. I must've been living under a rock not to of taken advantage of this outstanding tool. With the slightest bit of oil, I have the least amount of drag that I have had in the last two years of turning necks on casings. I just ordered my second one. If you haven't got one, you're missing out.
