Applications
This round indexable insert was specifically developed for medium milling. It provides excellent conditions for the efficient machining of steel and cast iron components. Thanks to the special coating of the RT300 grade, it is also highly suitable for use in stainless steels.
Typical fields of application include mechanical engineering, fixture construction, and general metalworking, where round insert geometries are required for profile or face milling operations.
Special features
A key feature of the RDKW RT300 is its PVD-coated carbide grade, which combines wear resistance with the necessary toughness. This supports continuous performance even under varying cutting conditions.
Furthermore, it is available in four different sizes to flexibly meet specific milling requirements regarding depth of cut and feed rate. The provision in a 10-piece packaging unit ensures economical stocking for professional use.
