These Titan hammer drills loads of other brands like them, do there job well. They are only a cheap hammer drill, but good for small jobs or home use. This is a common problem for them, as they do tend to get abused. The tool holder van become packed out with dirt meaning it no longer holds onto the drill bit or chisel. #titan #titanhammer #cheapandcheerful #sds #drill #toolholder #quickfix #tools #powertools | Deandohertygreaser
