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

They work great. Clean the copper fast and clean ready for flux and solder no leaks.I bought two more for next time.

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.

solo funciona 2 veses y se daño no sirve de muy baja calidad

As cool of an idea it is. I thought everyone knew to grab a fitting brush with some pumps just below the handle. Then pivot the handle back and forth till it breaks off. Now you can put the fitting brush directly into a drill.

The best multi tool

Part looked to be good quality, but wrong size was sent to me. I received the 3/4 brush size and not the 1/2 that was listed.

Alright folks, listen up! Yes, there are design flaws. But they are very, very easily remedied. Read on for how to overcome the problems with this awesome hella timesaver tool! The problems mentioned in other reviews are correct. The design is such that the problems are unavoidable. 1. The OD cup detaches from the shaft. When plastic is attached to metal in a tool specifically used for torsional stress, it will eventually break (sure wish things were still made of metal!). One can hasten this break by using an impact driver, or operating at too fast a speed, or pressing the cup too deeply onto the pipe. Even if one does none of these things, the plastic will eventually break where it bonds with the metal shaft. 2. The ID brush spins loose out of its mount. This only happens if the tool is used in a clockwise rotation (righty tighty). This is because the spiral wire that forms the shaft body is spun in a counter-clockwise manner. How to fix the problems: 1. Add a hose clamp around the skinniest part of the plastic, where it attaches to the metal shaft. You could probably also encapsulate it in some JB Weld if you really wanted to overdo it. Definitely use a low speed setting on your drill/driver. Consider not using an impact driver. And do NOT push too far down the pipe -- you only need 1/2 to 3/4 polished. 2. Set your drill/driver to counter-clockwise use (lefty loosey). Thats it! Just run the drill backwards when using the ID brush. Dont let the design flaws of this kickass tool keep you from buying it. If youve made it this far, youre already someone who can easily overcome the problems. Just make a sure you buy a tiny hose clamp at the same time (NOT a spring-style clamp, you want a worm-gear style).

Cheap , broke on first use

Inside cleaner brush broke on first, manufactured from poor materials or perhaps factory defect.

Wire brush dislodged immediately, one pipe half done type immediately.
