DrainXHeavy Duty Metal Drain Auger

I need something to clear roots from 3" irrigation drains. Not a lot of roots, will this work and accept auger attachments?

Is this the best option for clogged bathroom/kitchen sinks? If not, what are some other options? Thanks in advance.

How do you reel the snake back into the case? Do you have to push it back in?

The drill does not attach to the drainx. As it's adapter is smooth and round. Every drill is not. How does it attach?
