Cable sizing for 4"

Why wouldn't a 1/2" drum cable in my Rigdid K-3800 where the beginning of the cable is 7/8" thick be good for a 4" pipe? I've included of what my cable end looks like.

Some say its fine and some say no. Like I posted the cable does not navigate though a 3" unless its a straight run without any 90 involved. It doesn't go through a 3" P-trap either. Ridgid site says its good for 2-4"

Please describe why its not recommended and if you've had experiences with it.

My second question for a 4" that expand to a 6" to the street, what cable size and what Ridgid machine would you get in residential setting.
