30-Second Summary: Deep hole drilling is governed by a suite of German VDI standards (VDI 3208-3212), international ISO standards, and industry-specific specifications (NASA JSC-67701). The most recent update is VDI 3209 Blatt 1:2024-01. This reference provides an overview of each standard, what it covers, which job function should reference which standard, and how to obtain the full standards documents.

How to Obtain Standards
- VDI standards (VDI 3208-3212): Available for purchase from the VDI website (www.vdi.de) in German and English. Individual standards typically cost 100-200 EUR. Also available through DIN Media (www.dinmedia.de).
- ISO standards: Available from ISO member bodies or directly at www.iso.org. National standards bodies (DIN in Germany, BSI in UK, ANSI in US) sell ISO standards, sometimes with national adoption prefixes (DIN ISO, BS ISO).
- NASA JSC-67701: Available as a public document through NASA's technical standards portal (standards.nasa.gov).
- JB/T 15208.1-2025: Available through Chinese standards organizations (SAC, GB standards portal).
- ASME Y14.5: Available from the ASME bookstore (www.asme.org).
Quick Reference Tip: Manufacturer handbooks from ISCAR, Sandvik Coromant, and Kennametal often summarize key VDI standard data — including recommended speeds, feeds, and coolant parameters — in a practical, application-ready format. While not a substitute for the full standards, they are an excellent starting point for process development and are freely available from the manufacturers. The ISCAR Drilling Handbook is particularly comprehensive, featuring extensive VDI data excerpts.
