DR to D-tilt to dash grab (especially if it trips.)
DR to grab.
DR to D-smash.
I haven't seen many MK's use Drill Rush as a combo starter. I know it's not an abuseable move, but it's fast enough to catch people off guard with. By the way, these combos only work if DR is aimed towards the ground forcing the opponent into the ground gives them a bit more hitstun.
