Just dropped off about 30 lbs of end mills to be reground.

I have never done it before.

The regrinding shop has an awesome automated CNC end mill grinding
machine. I was told that you just insert the end mill in it and the
machine figures out everything and costs $300,000. It is a
technological wonder.

Their prices are $7 for a 1/2" end mill and $17 for a 1 inch end
mill. I will see how it works out, I will probably sell the big 1
inchers and will keep the smaller ones.
