You're so wrong. Why the hell would you be using a hammer drill on wood? First mistake. Hammer drills are for brick, concrete and masonry.
Second mistake, a professional grade impact driver with an auger tip bit will just roar though any wood, even <em>lignum vitae</em>.
I guess you didn't know that.
And, using such a bit in a professional grade impact driver eliminates the danger of kick-back.
