Well, I guess it takes all kinds. I was watching a video the other day and this man was drilling a well with his Kubota, that had a hydraulic hammar attachment. It seemed to work well enough but this was the first time that I had ever saw this setup. The end of the hammer had a pipe setup that did little or no damage to the threads on the drilling pipe. I had never seen this and thought it was interesting. I will search for the video. Ken
Was it a hammer or a drill?
A hammer.
I may have been mistaken. It could have been a drill. Something similar to this.
