Are there any special tricks to machining copper ?

I need to bore out some half inch sock x mt adapters to add pipe to the
threaded end for thermowells.

I make copper EDM electrodes all the time. it wants to grab and smear. I
blunt all my tools with a short land of 0 rake right at the cutting edge. I
just use a stone. i use WD-40 for cutting lube.

Use evaporated milk (in a can) for cutting fluid. No kidding.

My father taught me that when I was about four years old. My very proper
grandmother (DAR, WCTU, New England blueblood) almost had a stroke when I
recited it at Christmas dinner when I was five or six.

And Dad was, no doubt, rolling on the floor, holding his sides from
laughing.

I know I would have been.

In my case it was senior son telling Grandma

"Jack and Jill went up the hill
to fetch a pail of water
Jill forgot to take the pill
and now they have a daughter."

Nah, Gerry, it went like this:

Jack and Jill went up the hill
Each with a buck and a quarter.
Jill came down with two-and-a-half,
(they didn't go up for water).
