Tools cutting right into driers (7)
I believe the answer is:
trowels
'tools cutting' is the definition.
'trowels' can be an answer for 'tools' (I've seen this before). I'm not certain of the 'cutting' bit.
'right into driers' is the wordplay.
'right' becomes 'r' (common abbreviation).
'into' indicates putting letters inside.
'driers' becomes 'towels' (I've seen this in another clue).
'r' going within 'towels' is 'TROWELS'.
(Other definitions for trowels that I've seen before include "Garden tools" , "Tools for gardening and plastering" , "Garden implements" , "Small hand tools" , "Hand tools for scooping" .)
