Beware of stupid posts!

A coarse thread 3-1/2" deck screw has approx 28-35 threads. At 100
rpm, that's a minimum of just over 15 secs to drive one screw. Who is
so stupid as to want a screwdriver slower than that?

nb

Impact drivers are far far better at the task than a drill/driver. As
for drill RPM, my Makita and Hilti drills both start from near zero RPM
and quite often those low RPMs are needed when getting a bit started
properly on center, getting a screw point started, etc. Again remember
matsu****a and run the other way with any of their brands.
