Is This The Best Residential Drain Cleaning Machine? RIDGID K9-12 FlexShaft Review 

The built in clutch could be worn out, if the tool is under warranty Ridgid should be able to repair or replace it.

I have similar issues. over never been able to get it through a p trap. Even a 3"

It does but you should still use the clutch on your drill

They sell carbide tipped chains that are made for removing rust and mineral deposits, but carbide chains are only suitable for metal pipes.

It makes it through turns or even P-traps just like a normal drain cleaning machine, it is just as flexible as a traditional cable of the same thickness.

You left out lots of info. 1, they prefer it to be run at higher rpm so that the chain will clean the walls. 2, they say you should be running water while this is being used to help flush bits being broken loose. 3, they also say, if possible, push through the clog, then run the water and start the drill, cleaning as it is being pulled back. 4, if it's a harder clog, say solid grease, they say you may need to poke a hole through it first with a standard auger first, in order to get this into the clog. The bigger units have the option to add a head to cut into the clog.

@@stevem1081I have this smaller Flexshaft and use a penetrating head on the end of it and it works amazing

@@stevem1081 This smaller unit does not have the option to add larger heads, just the small chain heads.

The machine is a little pricey but for me it paid for itself on the first use compared to hiring a plumber. Ridgid does sell their tools in Ireland, you could check with a local plumbing supply store.

@@DragonBuilds thank you very much for your prompt response 👍. I well check it out

This drain cleaning machine is designed for smaller drain lines up to 2". I have used it on a 3" pipe and it worked, so I think it should work for soft stoppages on toilet drains.
