If you are going to cut copper ... I would spend the money on solid carbide endmills as you won't be getting ones over 1/2" diameter anyway and in smaller sizes they won't be any more expensive... maybe even cheaper.
JFetting had a good source for those
JTSMachine. I personally have an outlet less than 2 miles from my home, so I just walk in... and get what I want.
Go with four flute in any case as they are stronger.
I thought I remembered someone saying that they had that particular mill... can't for the life of me remember who... :shrug:
It does look like a nice small mill to me...
Edit: JFetting posting in concert again... I have to get this thing tuned...
