User can use the Engineers Black Book drill point sharpening gauge for checking the drill point accuracy. Additionally, a few steps should also be followed for checking the length & angles of the drill tip. In order to test if the drill is properly sharpened, the user can drill a soft material while carefully observing the chip formation. In case the drill point is properly sharpened the chips will come out in curled spirals of the same length. If the drill point is not balanced & incorrectly ground, the drill bit will produce oversized & out-of-round holes.
