How to use this check
Overhang ratio (L/D) = unsupported tool length ÷ tool diameter. A lower ratio normally improves stiffness, reduces deflection, and supports a more stable cutting process.
This is a practical screening guide, not a substitute for a machine, holder, toolmaker, or process-engineering review. Holder runout, gauge length, material, engagement, and machine condition also matter.
