New gear included universal implement (5)
I believe the answer is:
auger
'implement' is the definition.
(auger is a kind of implement)
'new gear included universal' is the wordplay.
'new' is an anagram indicator.
'included' is an insertion indicator.
'universal' becomes 'U' (film certificate).
'gear' anagrammed gives 'ager'.
'ager' placed around 'u' is 'AUGER'.
(Other definitions for auger that I've seen before include "Boring instrument" , "A drilling tool" , "Tool with spiral point for boring" , "something that's boring" , "A tool for boring hole in wood" .)
