How to select the correct CHICAGO-LATROBE jobber length drill bit?

Select based on material and hole tolerance. For aerospace alloys, choose a 135° split point like the #30 (0.1285 inch) to reduce thrust. Ensure the bit meets NAS 907 Type B if required by your contract. Match the diameter to your fastener or reaming allowance; black oxide HSS suits general-purpose drilling.
