EcoCut offers an innovative detail solution for
range 2.25D, namely additional bidirectional
coolant supply for better chip evacuation. An additional back-
wards directed coolant stream improves chip evacuation
from the flute area. A minimum coolant pressure of 1.5-3 bar
(optimum 5-7 bar) is required.

If the necessary coolant pressure is not available, it can be
advantageous to interrupt the cutting action in order to clear
the bore.

Deep bores up to 3xD

With a stepped bore approach EcoCut tools
EC..1.5D can be machined with holes of up to three
times the nominal diameter (see picture). Operation sequences
1, 2 and 3 respectively should be followed.
