The tip of the metal rod broke in the casing after only 2 days of use. The edges where it broke have widened and now the tip is stuck in the tube and won't come out. Since I can't get the broken part it looks like it ruined my new hammer drill and now I have to buy another one to replace it. Why sell something that will soon break. I could understand if it broke on the blade or even the exposed part of the shaft. But a tip? Thank you for giving me my time and money back.
