Neck Turning Cutters?

[John S]

Can the cutters on neck turning tools be ordered with a requested angle at the neck junction or are they all the same?

Such as 20, 25, 35, 40 degrees etc.

Maybe it doesn't make any difference??

Sinclair International makes a 40 degree cutter for their NT-3000. I purchased one because I have several Ackley chambered rifles that require neck-turned cartridges. It works.

It appears

The 30 degree cutter is close enough for everything but the 40 degree improved stuff.

Is it?
