Main considerations
The Silent Tools boring tools reach a maximum of six times the
bore diameter into your workpiece. If you need to go deeper, ask for
an engineered solution.
Our recommendation is to always use Silent Tools for long over-
hangs, over 4 x BD.
Tool overhang and diameter of tool
• Choose largest Coromant Capto size possible
• Choose shortest possible basic holder
• If possible, use a heavy duty basic holder
• For overhangs over 4 x BD,
use dedicated tools, e.g Silent Tools.
