Weiler 36303 1/2 Inside Diameter, 5/8 Outside Diameter, 302 Stainless Steel Bristles, Turbo Tube Brush, Made in the USA

I dont know what the review means by asking for warmth. This tool will clean copper pipe very quickly, but it does heat up the pipe; maybe thats what they mean. When PEX wont do, I still sweat copper and am always pleased at how much more quickly it goes using this tool. Bought my last one 4 years ago and it finally wore out, so I was glad to see that they still make these.

The inside diameter brush works nicely, but the outside diameter brush failed on its second use, not second use on this job, but second use since being taken out of the package. Like the other review mentioned, the hex bit spun inside the plastic housing for the OD brush. The plastic hub is too big to fit into a 1/2 drill, so I ended up using the OD brush manually, which defeats the purpose of a powered brush. All Weiler tools will be suspect to me now.

Good quality

Works great, but way too expensive. The internal fitting cleaner is what you need and it is much more economical to just take a fitting brush (a couple dollars) and cut the handle of and stick the brush in a battery drill that has a chuck. I have been doing this for some time and it works just the same for a fraction of the cost. Just stick to sandpaper for the outside of the pipe.

This thing works great. Saves a ton of time. The bad reviews are most likely from people who do not know how to use it properly. The red part of the tool slides forward, (completely burying the inner wire brush in the middle section of the red part) to clean the outside of pipe, then slides back(to expose the inner wire brush) to clean the inside of fittings. Im betting the people who broke theirs were accidentally cleaning the inside of the pipe, big no no. One star taken off because the red outside of pipe cleaner can be difficult to slide causing you to force it and scrape up your fingers or hand on the inside of fitting cleaner but Im not sure if it would work as good if it was looser.

It broke.

This copper pipe and fitting pre-solder prep brush for power drills is working out very well. It takes only a few seconds to prep the pipe and fitting, and it spares you from getting a repetitive-stress injury like tendonitis when you have many pipes and fittings to prep on a project.

Inside wire brush broke single use.

it snapped in two the instant I use dit

Broke after only using twice
