deep hole boring - Practical Machinist

Jan 16, 2011· The grind on the drill is crucial. One major cause of wandering holes is an improperly centered drill point. If this is a resharpened drill, inspect it closely to ensure that both cutting edges are the same length. An ialance in lip length means an ialance in cutting forces, pushing the drill off-center and causing a wandering hole.
