Walter Introduces Three New Milling Grades with Advanced Technology



The new WKK25S, WSM45X, and WNN15 milling grades from Walter deliver higher cutting speeds and significantly better tool life.



Waukesha, WI – Walter has introduced the WKK25S, WSM45X, and WNN15, a trio of hard working new milling grades that deliver an array of benefits to the user, thanks to Walter’s use of innovative cutting tool technology.



WKK25S features Walter’s Tiger•tec® Silver PVD cutting tool material, providing increased hardness (from 2200-2500 Vickers to 2500-2800); higher crystallization; and significantly decreased number of micro defects in the coating surface. All this translates to increased cutting speeds and higher cutting edge life. WKK25S is specially suited for the machining of cast iron materials.



WSM45X, with Tiger•tec® Silver CVD and post treatment, boasts excellent process reliability and excels at the machining of stainless steel (ISO M) and super alloys (ISO S). It has a broad application area that includes common aerospace materials. In field tests, WSM45X has shown tool life improvement of up to 50% and increases in material removal rate of 25%.



Walter’s WNN15 features innovative PVD technology. Known as High Power Impulse Magnetron Sputtering (HIPIMS), the new coating technology results in very dense and smooth coating layers. For the user this means reduced friction, significantly reduced build-up edge, good resistance against flank wear, and good cutting edge stability. Particularly effective with ISO N materials, application areas for the new grade include demanding aerospace work.



Walter, a global leader in the metalworking industry with over 90 years of experience in precision cutting tools for milling, drilling, turning, boring and specialized tools, helps customers improve process reliability and increase productivity. With Regional Headquarters in Waukesha, WI, Walter markets its competence brands Walter Valenite, Walter Titex, Walter Prototyp and Walter Multiply through a strong network of distributors and field engineers across subsidiaries in the USA, Canada, Mexico, Brazil and Argentina.
