The is no general rule to cutting tool shank insertion as a multiplier for shank diameter. All tool holder types have different requirements.

When using a high-performance drill, we do not recommend turning on coolant until the drill is inside a 1-2xD deep pilot hole.

Sure, there are 15 new geometries—including flat-tip and radius micro engraving mills, TC2 high-performance drills from 3xD to 30xD and pilot/step drills—but, Volume 2 of the Sphinx High Precision Cutting Tools catalog is much more than product listings.
