Delivery of fine motor-launch (3,6)

I believe the answer is:

off-cutter

I'm a little stuck... Click here to teach me more about this clue!

'delivery' is the definition.
I don't know anything about this answer so I cannot tell whether this works.

'of fine motor-launch' is the wordplay.
'fine' becomes 'f' (abbreviation).
'motor launch' becomes 'cutter' (I've seen this before).
'of'+'f'+'cutter'='OFF-CUTTER'

Can you help me to learn more?

(Another definition for off-cutter that I've seen is " Cricket ball".)

I've seen this clue in The Telegraph.
