Tools or grates (5)
I believe the answer is:
rasps
I believe this clue is a double definition.
'tools' is the first definition.
(rasp is a kind of tool)
'grates' is the second definition.
(I've seen this before)
'or' acts as a link.
(Other definitions for rasps that I've seen before include "speaks hoarsely" , "Grates harshly" , "fruit briefly" , "Coarse files" , "Scrapes" .)
