Seco (Warren, MI) offers its first range of Duratomic™ grades developed for milling applications. Seco is positioning the three new products— MK1500, MK3000 and MP2500—as its ‘first choice grades’ for a range of milling applications in cast irons, steel and stainless steels. Seco recommends MK1500 for easy to moderately difficult machining in grey and nodular cast irons, particularly at medium to high cutting speeds. MK3000 has the toughness and wear resistance necessary to face mill cast iron at medium to high cutting speeds, in operations ranging from easy to difficult. MP2500 meets the requirements for milling both steel and stainless steels. The Duratomic coating is Seco’s answer to an age-old metalworking problem where having high levels of both wear resistance and toughness has traditionally been impossible in a single grade. Manipulating the coating at the atomic level has allowed Seco to provide both characteristics, which means improved cutting data and longer tool life across a wide range of applications.
