DeWalt DCD799B Atomic Hammer Drill vs DeWalt 20V MAX XR Hammer Drill DCD1007
The DCD1007 is the stronger tool: more torque, higher speed, a 3-speed metal transmission and an anti-rotation safety system. The DCD799B is the compact, lighter pick for tight spaces and overhead work, and it is sold as a bare tool. Reviewers praise the DCD1007's power and compact head but note its weight during long use. Buy the DCD799B for light masonry and cabinet work; buy the DCD1007 for heavy drilling in concrete, framing and metal.
- Choose the DCD799B if you want a short, light hammer drill for tight spaces, overhead work and occasional masonry, and you already own 20V MAX batteries.
- Choose the DCD1007 if you drill concrete, framing and large holes regularly and want maximum power, a 3-speed transmission and anti-rotation safety.
