Bform a tapered hole in the bottom of the work piece
Ccut an elongated hole in the bottom of the work piece
Djam in the work piece and tend to whirl it around
AI Explanation
The correct answer is D) jam in the work piece and tend to whirl it around. When drilling through a work piece, it's important to decrease the feed pressure as the drill point starts to break through the bottom. Failing to do so will cause the drill to jam in the work piece and potentially whirl it around. This can damage the drill, the work piece, and be dangerous for the operator. The other answer choices do not accurately describe what happens when the feed pressure is not reduced in this situation.
