Not the easiest of metals to machine I would agree as it tends to be

a broken tool, or clag up. To use a technical term. :-)

Phos bronze not much better, either....

I still wake up screaming about the time I had to drill 16 3/4" holes in
quarter inch stainless. And not free cutting either - it was a bastard

Depends whether it's drawn, rolled, or cast.
Cast is almost as easy as brass.

More nerve racking, is tapping several 2mm x 5mm deep blind threads in
