22cal Carbide Expanding Mandrel (.223")

(1 review) Write a Review



Over the past several months we have received many requests to make expanding mandrels from carbide. Due to this popular demand we are now offering expanding mandrels from carbide. Carbide reduces galling and scratching both on the inside of the case neck and the mandrel itself. We still recommend the use of lubricant when expanding case necks to make the operation easier.

These mandrels are ground from a 3/8” solid carbide blank and sized properly to expand case necks, preparing them for neck turning. They can also be used to iron out dings and flat spots on new brass not destined to be neck turned, preparing them for loading and bullet seating.

    Carbide expanding mandrel

    Posted by Robert on 27th Jun 2023

    Nearly perfect tool for expanding case necks. Noticebly more smooth than stainless steel. Hopefully will outlast SS mandrel. I only gave 4 starz because the nose is flat instead of round.
