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

The wire brush for cleaning the inside of copper fittings broke the first time I used it. Maybe the metal had a defect but for me it was a waste of money.

Broke right out of the package as soon as I put it into my first fitting. Cheap poorly made

Broke off on the first use. Looked like a good concept. Attached to light duty cordless drill, inserted into 1/2 copper, pulled trigger, snapped off instantly. Very disappointed.

Broke of the shank first spin, bad design dont buy. Use manual one will work be better.

Works as advertised. Saves a ton of time from doing it by hand. Would buy again.

it snapped in two the instant I use dit

Makes the job easier

Huge time saver.

Broke on first use

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.
