IDK, I worked in a cabinet shop for a couple years (building and installing custom kitchens), back then we used Makita 9.6V and 7.2V drills for everything. It was rare to need to break out the 18V or corded drill. The owner bought some of the new Bosch Li-Ion compact drivers, but a lot of the old Makitas still work after over 10 years of constant use. Big drills suck unless you need a big drill, IMHO.
