I got this for the obvious reason. If you order this for any other reason other than stripping copper wire, you'll hate what I have to say. Great tool. I've had other drill and manual driven strippers that cost far more and produced the exact same result. This one however came with mounting hardware, as well as some replacement parts. The cutting wheel isn't one of the replacement parts. A smart move for the manufacturer would be to sticker their product with a phone number and or a web address so I am not scratching my head as to who I am going to buy that from. If you are stripping thhn with ?simpul on it, just keep pressure feeding it as you drive it through. A low speed on your drill may not be low enough. I used a Ridgid Gen 5 standard hammer drill, not that the hammer aspect of the drill was in operation during this process, just so you have an idea what I was using. Once I had made my adjustments starting from largest awg to smallest awg, the whole process went very smoothly.
