Juice extractor (6)
I believe the answer is:
reamer
'juice extractor' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for reamer that I've seen before include "Boring tool" , "Tool for enlarging drilled holes" , "Dentist's drill for enlarging root canals" , "Dental tool" , "Tool for shaping holes" .)
