Recommended width of cut (ae) is more than 60% of the cutting edge diameter.

n(min-1)= (Recommended Cutting Speed x 1000) u The above cutting conditions are guides to cutting on a #50 BT machine. In case of
(Outer Tool Diameter x 3.14)
#40 BT and #63 HSK machines, a cutting edge diameter of under 35mm is
recommended. In this case, reduce the depth of cut and table feed rate.
Use of chipbreaker with tougher cutting edges is recommended for machining
parts that require interrupted cutting. First recommended insert grade for
non-standard 06/08/09 chipbreakers is irrespective of the workpiece
material.
Cutter body with coarse pitch is recommended for the unstable cutting caused by the
long tool overhang.
Use the "sharp" chipbreaker to lower cutting forces or when long tool overhangs
ROTATING TOOLS are used.
Heavy chips are generated when machining with the . To avoid chip
jamming-related problems, use air blow while machining to discharging chips
effectively.
