E Notes
• When tapping a W deep hole, keep its bottom's incomplete thread 3mm or less. • Tighten the runner ejector set firmly using a spanner on the housing's notch. This forces the housing's flat bottom surface to be pressed hard on the tap hole bottom,and helps prevent the runner ejector set from loosening.
