My two sons use cordless drills, but it is because in their work they are usually in places with no power.
I've got maybe four corded drills, all work. The oldest is a B&D I got in about 1975, and is the one Iuse the most - it is smaller than the others. I've got power in my shop, which is where I usually use them, and extension cords for use outside the shop. I'll stick with corded drills.
NC via the Army in 1979; retired 1981, just east of Raleigh ever since.
Remember, when I tell how I do something, that does not mean I recommend you do it my way. Different backgrounds, experiences; what works for me, may not for you.
