Hi all In this video minute (0:40) the person is using machine to screw. What this machine is? a drill with special head or what? I have a drill but not cordless and i am thinking to use it as a screw driver to screw a big board for my front house, or do I need special device? Thanks https://www.youtube.com/watch?v=fkOVc9FtozA

We need to know if your drill has one speed, two speeds, or is a variable speed control type of drill.
