The grade and geometry are ideal for machining materials such as titanium, cobalt-based alloys, and Inconel 718.

Waukesha, WI — Walter has introduced WSM01, a premier grade for demanding machining applications. Coupled with Walter’s new MS3 negative geometry it produces burr-free results with high surface finish quality in the hardest materials. The WSM01 difference stems from its HIPIMS PVD coating method. Unlike standard PVD coating which deposits discrete droplets upon the target surface, HiPIMS (High Power Impulse Magnetron Sputtering) PVD coating produces extremely smooth surfaces leading to reduced friction in machining. The new coating is characterized by an excellent layer bonding and thickness distribution, reducing the tendency of ‘flaking.’ Extra smooth surface of the coating and extremely sharp cutting edges keep edge build-up to a minimum and ensure high surface finish quality.

This new insert is particularly suitable for machining unstable or thin-walled components. The MS3 insert is equipped with jet-guiding geometry to ensure optimum cooling directly on the cutting edge and is particularly well-suited to copy-turning applications and medium machining applications in aerospace, automotive and general metalworking industries.

The combination of the WSM01 grade’s HiPIMS PVD hard layer and the new MS3 geometry is ideal for machining ISO S materials with difficult cutting properties such as high temperature alloys, titanium alloys, cobalt-based alloys, and nickel-based alloys such as Inconel 718. A secondary application of this new grade is with ISO material groups M (stainless steels), N (non-ferrous alloys such as aluminum and P (steels).

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.
