That tool would be great if you are doing all the flaring on the bench but when doing the flaring on tubes that are installed in the car the common style of a flaring tool works. I use the KD flare kit
It was the copper nickle & steel lines I got it for. I'm not as ticked as I could be since I knew better than buying anything with their name on it. For any aluminum lines I'll just see If I have luck with the 45 degree flare since it's working for you but I need thinner wall tubing as what I have is too thick since it's from the local hardware store.
