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

A portable battery-powered screw gun like the one in the video is probably
the best option. But, if the regular plug-in type (not battery-powered)
drill that you have is variable speed and reversible, then you could
probably just use that for now. You would just need to by a
screwdriver-type bit to put in in -- either a Philips head type like this
one

or a flat head type for flat head screws.
