What is a screwdriver like this called?

[Sparrowhawk]

I have a number of stiff screws to get out, either overtightened or seized in place, that I can't shift with a screwdriver or with my 10.8V Bosch PSB 10.8 LI-2 Cordless Combi Drill.

 

So I found a screwdriver with a hole in the handle and I've been putting my body weight on it and exerting force via another screwdriver through the handle. No screw has won - yet.

 

But this bodge has damaged the screwdriver through the handle. As there's more to remove, what's the proper type of screwdriver to do this with?

Impact driver.

Just twist the right way, then twat it with a mallet.

Thanks, was googling for "Socket screwdriver" which doesn't seem to exist, and "ratchet screwdriver" which is something else.

 

Edit: Do socket sets take screwdriver bits? One 2.5 inch screw I've just taken out from a wooden fireplace surround had to be levered out its whole length, so losening just at the start as a manual impact driver seems to do is unlikely to be enough for some of these.

Loosen with manual impact driver then use an electric drill/ electric impact driver? Should have thought that would work as long as you can stop the bit bouncing out.

Yes, socket sets do take screwdriver bits. A 1/4" drive to hex adaptor is the piece you need.

My bigger screwdrivers have a hexagon integral to the shaft. It is designed such that a ring spanner can be used to give increased leverage. I thought this was a standard feature of half-reasonable screwdrivers.

Failing that, my trusty Li-Ion Erbauer imact driver usually wins. But it chews the bits up in short order so have plenty of spares.
