It is true this machine has less torque than common full size 18 volt screw guns
But for quality work- tight screw installs can be pre drilled without the hassle of changing bits with hand chucks,
Since I opt for quality over speed, I would use two of these. one with drill and one with driver bit.
The tool is easy on your hands and get into those places that drive us all crazy to secure.
This is a must if quality is your goal.
