Hammer DRIVEN Impact driver

When you strike this device with a hammer, it applies the impact, as
well as turning force at the same time.
Might be worth a try. I have one of those and have used it to remove some
tough fittings. Didn't occur to me that banging and twisting on the head end
might be more effective than trying to simply drive the bolt from the
threaded end.

It's not quite a substiture for a pnuematic impact driver, but when a
compressor is not available, it's a good alternative.

Sorry, I missed what the OP's use would be, but for slotted/phillips
screw removal, the hammer version is actually much more effective, since
the downward (or inward if you prefer) force will keep the screw head
from stripping. For hex/allen heads, I'd agree with you about the
pneumatics.
