How to select the correct jobber length drill bit for aerospace work?

Select a drill bit that matches the material and hole tolerance required. For aerospace alloys, use HSS with TiAlN coating and a 135° split point to reduce thrust and improve chip evacuation. Verify the diameter (e.g., #16 = 0.1770 inch) and NAS specification (Type B) for compliance with industry standards.
