High-Performance Milling Insert RTHX-HM RT905H

The RTHX-HM RT905H milling insert is a professional solution for hard machining and precise finishing applications. Designed for hardened steels up to 68 HRC, this indexable insert delivers excellent performance through its combination of a wear-resistant substrate and a high-quality TiAlN coating. The coating minimizes friction, prevents the formation of built-up edges, and thus supports consistently high workpiece surface quality. This opens up economical possibilities for high-performance machining in die and mold making as well as other demanding metalworking sectors.

Applications

This milling insert excels particularly in the hard machining and finish milling of hardened workpieces. It is ideally suited for machining tasks in mold construction or general mechanical engineering, where hardened steel up to 68 HRC must be cut reliably and smooth surfaces are required.

Special features

The RT905H grade combines a tough, highly wear-resistant carbide substrate with a smooth TiAlN coating. This combination reduces process-related friction and heat generation at the cutting edge. The result is a reduced tendency for built-up edge formation and a uniform, defined cutting behavior even with difficult-to-machine hard materials.
