It will get one off drill (5)
I believe the answer is:
twill
'one off drill' is the definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Perhaps there's an association between them I don't understand?
'it will' is the wordplay.
'it' becomes ''t' (abbreviation. e.g. in 'tis).
't'+'will'='TWILL'
'get' is the link.
Can you help me to learn more?
(Other definitions for twill that I've seen before include "Fabric woven to produce a surface of diagonal parallel ridges" , "Fabric with distinctive weave" , "Fabric weave with parallel diagonal lines" , "Fabric woven to have diagonal ribs" , "Strong woven fabric" .)
