Pro Tool Reviews explains why the DCD806 can be a practical everyday choice even alongside the more powerful DCD1007. Its comparison includes the compact DCD799 and examines speed, output, tool weight and head length rather than selecting a drill solely by maximum power.
The source lists the DCD806 at 2,000 RPM, 1,050 UWO and 2.9 pounds bare. The DCD1007 offers more power but adds weight. This is the reviewer’s workload-based preference, not a verdict that the higher-output drill is unnecessary for demanding drilling applications.
