So you have a fresh install of Debian? You want to be able to install kali tools on your new setup, or at least some of them?
apt install python-pip
git clone https://github.com/LionSec/katoolin.git && cp katoolin/katoolin.py /usr/bin/katoolin
chmod +x /usr/bin/katoolin
Then either select which tools you wish to install, or press 0 to install them all.
