Possibly not as expensive as you think.
J&L here in the UK do a small 3/4" tool with one carbide insert.
Incidently it's the triangular one that seems to be standard in face
mills. cost here is about 72 UKP so judging by your prices it should
be about that in dollars. I can look the part number up but not
certain if US numbers are the same as Uk ones. I would have thought
they would be.
