Recommendation:
Maximum drilling depth:
clamping slot length (see table) less 1.5×nominal ⌀.
clamping slot length (see table) less 1.5×nominal ⌀.
Note:
For deep-hole drilling deeper than 16×D a pilot hole is recommended, and for deep-hole drilling from 20×D to 30×D it is essential. The generation of a pilot hole always improves process reliability.
