Inch values are official. Aviation is designed and worked in inches. Millimetres are converted and are not official; where one is shown, the metric drill is the nearest alternative, not the official drill.

Notes
- Withdraw in the cutting direction only: turning back can force chips in (H-31 p. 4-19). How much to leave for reaming differs by source: about 1/64 in (H-31 p. 4-20) or 0.003-0.007 in at most (H-30B p. 11-13). The repair data decides.
