The New Walter Prototyp Proto·max(TM)ST Z-5: A High Performance Solid Carbide Mill for High Productivity



Higher process reliability, increased tool life, lower costs, suitability for dynamic milling and excellent performance characterize the Proto-max™ ST.



Waukesha, WI – Walter has introduced a new version of its Walter Prototyp Proto▪max™ST high performance, solid carbide milling tool designed for optimum performance on steel with secondary applications in stainless steel.



This new entry in the Walter Prototyp lineup is called the Proto·max™ST Z-5, a solid carbide milling tool with five cutting edges, available with the same tough yet wear-resistant TAZ coating that is offered in the original three and four flute variations of the Proto·max™ST.



The new mill has five cutting edges, differing from the previous entries that were limited to three and four. It is available with a Weldon shank configuration for secure clamping, with or without corner radius, and without a reduced neck for greater stability by using the maximum amount of carbide. It possesses a helix angle of 35°, and is offered in the diameter range of 6-25 mm.



The new Proto·max™ST Z-5 delivers higher productivity by reducing process times, along with high process reliability by significantly reducing the risk of tool breakage. In addition, the TAZ coating dramatically increases tool life, and costs are lowered because of savings on coolant, as dry machining is the recommended approach.



Importantly, the Proto·max™ST Z-5 is well suited for dynamic milling, a highly productive machining strategy that is growing in popularity. Dynamic milling is a method of defining tool paths so as to maintain a constant tool engagement angle. This allows large depths of cut to be taken which fully utilize the entire cutting edge of the tool. This is normally combined with radial chip thinning, accomplished by taking a small radial depth of cut; around 10-15% of the tool diameter is actually engaged in the cut. This combination allows for very high speeds, plus very high feedrates and deep depths of cut, typically leading to high material removal rates and lower cutting forces.



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.
