Query: powerfull but built very poorly

I have owned this drill for about 6 months now and the chuck head has broken off twice already. It does not withstand even the smallest impact on the head of the tool. I dropped the tool from waist height once and it literally sheared at the clutch adjustment. The second time it broke was at the same point while drilling a hole with a 1 1/8 bit in a 2x4. If you intend on using this tool on the job, it will not last with normal use.
