Tool with high cutting rate and screw interface that devours metal

The solid carbide milling cutters from the Proto•max™Inox range are the tools from Walter that can really bite into stainless steel. The outstanding feature was always the large machining volume, and that still remains the same.
The tool now comes with improved holding options, thanks to Walter's trademark ConeFit™ interface. Proto•max™Inox milling cutters with ConeFit™ interface allow for substantial cuts into high-grade ISO M (austenitic stainless) as well as in ISO S-materials as a secondary application. The developers from the competence brand Walter Prototyp have measured a performance increase of 50 per cent compared with conventional modular tools on the market: This was possible thanks to a geometry with 50° helix angle and four cutting edges, a new TAA coating and, in particular, internal through coolant, which has been a crucial factor in increasing tool life by up to 50 per cent in tests. Internal cooling channels with radial outlets maintain a constant operating temperature and, as a result of reliable chip evacuation, ensure a high level of process reliability. The new TAA coating with a titanium aluminium nitride (TiAlN) base ensures that cutting edge integrity is maintained for much longer periods than previously achieved.
