Cast objects to cut (4)
I believe the answer is:
dice
I believe this clue is a double definition.
'cast objects' is the first definition.
(dice get thrown or cast in board games)
'cut' is the second definition.
(dicing is a kind of cutting)
'to' acts as a link.
(Other definitions for dice that I've seen before include "Random number generators" , "Small cube" , "Make into chips" , "Gaming cube(s)" , "Cubes used in gambling" .)
