Ummm, Ted. The only thing we used that tiny an insert on was one of
the shaft gears we used to make.

Your point?

normalized forging. Industry didn't design carbide for slow light
cuts. It's meant to rip metal off as fast as possible. Home shop
machines don't have the backbone to handle what the carbide was
intended for.

The considerations of a production shop are kinda irrelevent in a thread
on light home shop machines. Your idea of optimum isn't the same as
mine.
