That’s a *DCA Rotary Hammer Drill*, in the DCA teal carry case.
*What it does*: 3-in-1 tool for heavy-duty drilling and chiseling. That dial on the side with the red arrow switches modes:
1. *Hammer + Drill*: For drilling into concrete, stone, and masonry
2. *Drill only*: For wood or metal
3. *Hammer only*: For chiseling and light demolition
It uses *SDS-plus bits*, which lock into that chuck at the bottom for better power transfer and no slipping. The black side handle helps control vibration and gives you more leverage.
Good for construction, electrical, and plumbing work. Way faster in concrete .
