Man turning something that won't come free without power tool (4,5)
I believe the answer is:
nail punch
'man turning something that won't come free without power' is the definition.
I know nothing about this answer so I cannot tell whether this works.
'tool' is the wordplay.
I cannot really see how this works, but
'tool' could be 'punch' (punch is a kind of tool) and 'punch' is located in the answer.
The remaining letters 'nail' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for nail punch that I've seen before include "Hammered tool" , "driver getting hammered" .)
