Enlarge a hole
I believe the answer is:
ream
'enlarge a hole' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for ream that I've seen before include "20 quires of paper" , "480 sheets of paper" , "Widen out (bore)" , "Widen (hole); quantity of paper" , "stock of paper" .)
