Great tool! Make sure you are using a corded drill and not a cordless drill for this tool to work properly, it needs as much power as possible.

I had purchased this awhile ago and use it for the first time and had bad results because I had use it on my portable drill on full. It had broke when it had got caught on the caliber. That being sad I call the company and they recommend to slack off on the drill to lower setting. This work fine and now if it gets jammed it will just stop spinning. The company also replaced the original one with a new one. Hope this helps everyone that uses it. It does a good job cleaning the wheel without removing it. Saves time. Good luck!
