This demolition drill held up well but didn't work for me. I don't attribute this to the club but to my demolition hammer as it is rated at 11 pounds. impact energy. I highly recommend that you have at least 20 pounds of impact resistance if you plan to use this attachment effectively. That being said, I can say that this beat is solidly designed and built. Just to reiterate, this is not a negative review of the bit, but rather an indication that this bit does not work well with a low powered jackhammer. I'm sure if I had an impact rating of 20 pounds (or higher) my experience would have been a lot better. The width of the blade was just too wide for my demolition hammer to use this bit effectively.
