Machining of NF metals Product overview Edition 2022 _WALTER PRODUCT HIGHLIGHTS Aluminium Tools – forming an excellent future

Aluminium is conquering a wide range of applications. In automotive and aerospace applications, it saves weight and CO2. In mechanical engineering, it reduces the machining time. Walter offers the perfect tool range for aluminium: Available in standard versions or customised via Walter Xpress. Whether you are roughing with a high metal removal rate or finishing with superior quality, whether you are using “soft” materials or highly-abrasive AlSi alloys: Walter tools for milling, turning, drilling and threading shape up aluminium components.
