Great addition to the toolbox - use the right tool for the job

Summary: Drilled through mortar much better than my regular rotary drill and it came with a carrying case!! great bargain Used the bosch blue something bits and it worked great. Kept the bit cool with some water and didn't need to put much pressure on the drill.
Summary: This tool performs very well and is up to my expectations. However, the enclosed instructions lacks clarity with regard to the affixing of the supporting handle. Also, the tool which tightens the bid has a strip of plastic wire attached to it.
