Actually, when a Bouncer attacks you it's his way of drilling into you. The Drill just doesn't impale you because that would incur serious technical/gameplay issues. The Bouncer's fighting style also mainly consists of spaced-out, powerful hits, so it wouldn't really work if he were to deal continuous damage.
