Argue about what to make a hole with (5)
I believe the answer is:
auger
'what to make a hole with' is the definition.
(an auger is a tool for making holes in wood)
'argue about' is the wordplay.
'about' is an anagram indicator.
'argue' with letters rearranged gives 'AUGER'.
(Other definitions for auger that I've seen before include "A tool for boring hole in wood" , "Boring-tool" , "A drilling tool" , "Tool with spiral point for boring" , "Tool for boring holes in wood" .)
