Walter Introduces M5460 Profile Milling Cutter with Internal Coolant for Enhanced Surface Quality

Walter AG, one of the world’s leading metalworking companies, is presenting a new profile milling cutter of the Xtra·tec® XT generation in the form of the M5460. The milling cutter (diameter 8–32 mm or ⅜–1") has an internal coolant supply which can be used with compressed air MQL (minimum quantity lubrication) or emulsion depending on the material and application.

This optimizes chip removal and therefore surface quality and process reliability. The Xtra·tec® XT milling cutter—designed for finishing, semi-finishing, and hard milling—is suitable for profile milling of complex freeform surfaces (for example, those on blisks) as well as for deep cavities in steel, stainless steels, cast iron, materials with difficult cutting properties, and for hard machining up to 63 HRC. The double-edged, precision-ground indexable inserts combine proven geometries with Walter’s universal, wear-resistant cutting tool materials for ISO P, K, M, and S and with the WHH15X high-performance grade for machining ISO H.

Walter offers the profile milling cutter in five different interface versions: with a cylindrical shank (steel and solid carbide), Weldon, ScrewFit, and cylindrical modular. The M5460 can be used universally owing to these options and also due to the wide variety of cutting tool materials, for example, in general mechanical engineering, aviation, or energy industries. Since the cylindrical modular interface is mainly used in the mold and die making industry, users are given a ‘plug & play solution’ for this. Other benefits include the higher cutting speeds that are possible and less rework due to the improved surface quality.
