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

This item lasted about 1 minute. The outer brush piece stripped out the plastic shaft.

Ill never clean 1/2 copper pipe the old way again. This does a great job. Note that the two parts can be separated. The brush that cleans the inside of a fitting can be put on the drill by itself. I prefer it that way. I have a perfect hex shank that allows me to use the other brush by itself too. I prefer that. But, their intent is to keep the two parts together and extend and retract the inner brush depending on which you need. That should work fine unless both brushes are accidentally grabbing at the same time.

Funciona perfectamente

Definitely speeds up the process while cleaning copper pipe. The lower drill speeds work well, thus saving wear and tear on the brush.

The thin plastic broke after a few uses, but the outside brush can still be used manually. The smaller inside brush does not attach to the metal rod in the center very well, but it still works. But after just a few uses, the inside brush has gotten smaller in diameter, so it doesnt work as well as it first did. .

the items total junk i like my money back it broke first time on the drill i wouldnt even give it one star

This thing is amazing. I was doing a big copper job and needed to sweat lots and lots of copper. I got one for 1 copper and the other for 3/4 mounted them in 2 separate drills (so I dont waste time on switching) and off I went. You honestly cannot beat this thing with any sandpaper or mesh or anything else that requires manual labor. I had these mounted in cordless drills and since the torque required to turn these gets up there I had to swap batteries pretty frequently but if you got them going on charge all the time you will never run out. Even after lots and lots of work it didnt get too dull which really surprised me. I was expecting this thing to die on me after like fifty times but it just kept going and going.

Total junk As I am laying under the house the main shaft detach from the plastic and it spins without cleaning the pipe. Its useless. Back to manual cleaning.

...but the wire inside brush fell out on the first use. Returned.

Very good
