name for this kind of high-torque screwdriver?
 
I saw an old-fashioned ratcheting high-torque screw driver with a vertical component in which the bit was housed, and a handle coming out of it approximately mid-way at a 90-degree angle:

___________ (handle
[ ]

The tool was about 12" tall and the handle was about 12" long.

I have an old woodworking tool with a filister head screw that won't budge even when I use a behemoth 18" screwdriver. I'd look for one of those old high-torque drivers but don't know what they are called.

I'm not sure either----I have placed a Crescent wrench on a square shafted driver with some success.

I used to have a hammer driven impact wrench which would hold a screwdriver bit--I used that a few times to free up ancient wood screws when disassembling old furniture.

One of these will break it free or snap off the head if it's rusted in place.

Not going to do any good to have higher torque if there's no dowward pressure preventing cam out.

That's the tool I used to use!

It's a hefty filister head with a deep slot. The beauty of that old tool, whatever it's called, is that you can bear down on the vertical while using the leverage of the handle, and you have much more control over the torque than you'd have when using an electric hammer drill.

Maybe one of those manual impact drivers would be better. I've never used one. Do you just twist on them slowly while applying downward pressure?

The last thing I want to do is break the head off, since it's holding the bearing clamshell in place.

In the meantime I'm going to PB Blast it and give it a day or two.

Many pro quality screwdrivers have a bolster below the handle that will accept a box and wrench. But the impact driver shown above is the way to go. Buy a good one. set the direction. Whack it with a hammer. They work. I'd apply a little heat first, so you don't twist the head off.

Damn, I HAVE one of those hammer impact tools, too. I bought it to work on my first motorcycle back in the day. It' still in my toolbox somewhere.

Remember the old "cordless" drills, the hand-powered ones? I think the screwdriver you are talking about looks similar, except the mechanical advantage created by the tool is different. For the drill, the speed was stepped up so the drill bit could spin fast and do its work. The screwdriver you are talking about must work the opposite way.

If I were you I would just use an impact driver. If you don't have one, you don't know what you are missing! The reason those tire shop guys make it look effortless to zip your lug nuts off is because it is effortless -- their tool does all the work. Look up impact wrench on Wikipedia if you want to know how one works. There is a good article.
