- When the pick feed direction is along the radius of the tool such as finish face machining.
Note 1) This cutting condition is the standard condition when using the steel standard shank type.
L If vibration or chipping on cutting edge occurs, please decrease the cutting condition as width of cut, depth of cut
and feed per tooth depending on the situation. Note 2) Recommended cutting speeds apply to tool outside diameter. Please calculate the spindle speed of tool in the following expressions.
