A comment
At the end of September 2013, I bought a Black & Decker KD 975 puncher. For a week I worked the puncher without any problems, but then I began to pay attention to the fact that grease began to appear under the switch, and the longer I worked, the more grease came out. It was no longer possible to work on it, because after work, I found myself all in grease.
Since the puncher was still under warranty service, in order to eliminate this problem, I brought it to the service, after a month of waiting (until the examination was completed), I was informed that the punch, due to factory defects, wore the sealing cuffs, brushes and bearings. Having put forward an offer in return, the same new punch.I took a new one, it works fine, the grease does not run, it drilled concrete floors with it, it drills perfectly! There are no complaints about the work of the puncher, I really like everything!
pros
the second time, the punch was above all praise.
