Sumitomo RCMX100300 AC4015K – Turning Carbide Insert

The Sumitomo RCMX100300 turning carbide insert, grade AC4015K, excels in general machining of cast iron workpieces, its Al2O3 coating providing a strong barrier against wear and heat while maintaining a sharp cutting edge. With a round shape and 7 degree radius, this insert is well-suited for turning operations that require a balance of tool life and surface finish. Its neutral geometry makes it a versatile choice for a range of cast iron machining tasks, from roughing to finishing.
