Brass tube wall thickness for edm

[Batmanacw]

I'm getting ready to order some brass tube for my ancient edm. I don't know what the ideal wall thickness is.

I received some 1/8" brass tube with the machine.

I'm planning on ordering some 3/16" and 1/4". Maybe some 3/8".

Mostly for burning out taps.

I used to order from company called EDM Supplies in Downey Ca .
I think wall thickness was about .015 thousands. Call them or you can get some tubes from Amazon. Maybe cheaper shipping. EDM also has types of supplies for tap extracting.
