Cutter grinding.

    Having watched this I am at a loss to see what is being adjusted by the Allen key.

    It is adjusting the stopper, that limits the depth being removed from the cutter being ground.

    I spotted the stop after I posted. Lol but I was blinded by the fact he is grinding on a round wheel. But it's trying to get a flat on the end of the mill.

    He's not trying to get a flat on the end of the cutter - he's grinding a concave facet.

    There are tables giving all of the 'heights above centre' for different sized wheels - here is one from the Norton hanbook.

    With that cutter you only really cut on the sides, unlike a slot drill. All he is doing is cutting clearance.
