I got an adaptor for the ridgid K50 sectional cable and I have cleared a couple of kitchen drains with a battery drill and cable only. Only thig is it is better as a two man job the cable wants to kink outside of the drain so you need to not have too much slack one person runs the drill the other person feeds the cable in. I am using heavy duty 5/8" cable with no sleeve on these two jobs.
Only good thing was not stringing out a cable and hauling the K50 and guide hose up on the roof to go down the drain.
I have also used the same system with a t-slot carbide head to do some light descaling and grease removal form drains.
I used a 3/8" General cable 75' sleeved in 1/2" pex to try and clean a few main line stoppages. One was more than 75' so no luck that time.
Did you end up getting flex shafts to use on a drill from plumber-tools?
Anybody ever connect two flex shafts together made from drum cable and pex?
These are two things I want to sort out in the future.
Got an old dewalt angle drill that spins 1500 rpm sitting on the shelf and plenty of drum cable to play with. I'm thinking for outside cleanouts and open pipe in the ditch. Just thinking through a setup that gets me over 100' like the Picote does.
And the other thing, once I test it out, we might put a smaller flexshaft bare cable/drill setup on the service trucks. Quick in and out kitchen and laundry lines.
