As to crimping tools it’s important to use the correct power pole tooling as the alignment of the crimp is critical to contact insertion.   

Ive found the West Mountain Radio tool to be good for the smaller powerpoles  I’ve got the Anderson crimper for the 75 amp powerpoles.

Anything larger - i use a local assembly house which has hydraulic crimpers for Anderson connectors.

I used powerpoles on a project and tried to use a crimping tool I had to
hand. Amphenol, I think. It appeared to be the right size but ended up
bending the terminal badly where it changes from circular to flat. The
results were unreliable and I ended up soldering (though adding sleeving,
which together with the natural bend-restriction on the shell has mostly
avoided stiffening the wire where it's most vulnerable).

I know some crimp terminal are very fussy about the tool used but it's
usually the miniature ones like JST. Does the powerpole terminal need a
powerpole-specific crimp tool ? I note that the West Mountain tool seems to
be branded by themselves rather than Anderson, but I can't tell if it's
generic or made to their specs.
