Solid Carbide Endmills - Walter USA LLC

March 7, 2014

Walter has expanded its “Tough Guys” series of high-performance solid carbide endmills with the new Walter Prototyp Proto·max™TG (the TG stands for "Tough Guys"). The Proto·max TG is a versatile performer that can be used on steel, stainless steel, cast iron and in many cases on super alloys. The endmill provides excellent chip removal and guarantees sufficient room for the chip removal for slot milling up to 0.9 x Dc. The rear cutting edge has a reinforced core, giving the tool a high degree of stability. The cutter is available with a reduced neck as an option, and is ideally suited to plunging or inclined plunging for deep cavities. In addition, it is also suitable for pocket, contour and shoulder milling. 

The Proto?maxTG is available in 2 to 25 mm dia., with three, four or five cutting edges. In addition to its performance-enhancing design features, Proto·maxTG boasts an advanced carbide substrate. This substrate provides for an extremely high level of toughness -- important for counteracting vibration induced fractures to the cutting edge. An advanced pre-treatment process provides an optimum surface for the tool’s new titanium aluminum nitride coating. This new coating helps protect against wear thus increasing tool life. These three features – substrate, cutting edge treatment and coating – combine to dramatically increase Proto·maxTG cutting parameters by up to 100%. The new Proto·maxTG joins three existing models in the Walter Prototyp Proto·max™ family of solid carbide end mills. These are the Proto·max™ST for steel, Proto·max™Ultra for hard materials and Proto·max™Inox for stainless steel materials.
