Description
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.

Excellent product
I just started using expander mandrels and owned few in stainless steel and this one in carbide. The carbide is a lot smoother . I love it that it’s compatible with 21stCentury dies . I just wish these are made in different diameters too.

26 Cal carbide expander
This is easily the best expander mandrel I’ve ever had. Very smooth and durable, it should have a very long service life. If you want the best expander mandrel this is it.

26cal/6.5mm Carbide Expanding Mandrel
I've not yet used this product but if it helps with my 6.5 Grendel reloads as well as the 6mm Mandrel did with my 6mm ARC, it will deserve the 5 stars I gave it.

works great
just started using this as a last step before loading and it has helped shrink my SD to low single digits (2-3 fps)

Easy to use mandrel to equalize neck tension
The mandrel does what it is supposed to do; open the neck from the inside to a consistent size from the inside. Neck bushings are a guess assuming all your necks are exactly the same and have the same "spring back" The mandrel does a better job of creating brass with equal neck tension

6.5mm Carbide Expanding Mandrel
I use a bushing die to reduce the neck OD, then finish size the neck ID with the expanding mandrel. I use a pin set to check what ID I have produced. The .262 pin goes. The .263 pin is a no go. The Carbide Expanding mandrel give me about 1.5 thousandths neck tension. This works well in my gun.
