GENERAL TECHNICAL INFORMATION Recommended Cutting Conditions Recommendations given are normal machining conditions. If excessive wear occurs select an insert in a harder grade. If chipping or breakage occurs select an insert in a tougher grade. The high end of the cutting speed recommendations given are for insert widths of .118 inch and over at low-to-medium feeds. For smaller insert widths or machining at high feeds choose a lower cutting speed. Optimal grade selection depends also on workpiece material diameter and rigidity of the system.
