Best setting for pipe command to mimmick milling lettering at sharp corners?

Hi,
V5.
To add some text and an arrow to a milled mdf block, I am told draw just lines and I can get the milling software to follow the lines with the smallest head (2mm dia)

How can I use the pipe command to avoid making the arrow head pointed sharp as opposed to the result of using a 2mm dia sphere cutter. ?

Is there a way of telling pipe to follow a sharp bend as a milling cutter would ?

The only way I can see is to use separate curves.
