Tool in bench is electric (6)
I believe the answer is:
chisel
'tool' is the definition.
(chisel is a kind of tool)
'in bench is electric' is the wordplay.
'in' indicates the answer is hidden within the clue.
'CHISEL' is hidden within 'bench is electric'.
(Other definitions for chisel that I've seen before include "Hand tool to shape wood" , "Sharp tool" , "Sharp-edged metal tool" , "Eg, woodworking tool" , "Sculpting tool" .)
