RFEN2004M0 KS20 RFEN indexable insert for milling by Tungaloy

The RFEN2004M0 KS20 is a round indexable insert designed for milling applications in Tungaloy milling systems, offering a balanced combination of wear resistance and toughness for demanding cutter assemblies.

• KS20 grade: wear-resistant and tough
• Round 20 mm insert, 4.76 mm thickness
• Designed for Tungaloy milling systems

Precision and longevity for continuous machining

The insert is manufactured from carbide and specified in the KS20 grade, which pairs wear resistance with sufficient toughness to preserve the cutting edge under typical milling loads. This combination reduces flank wear and helps maintain a consistent surface finish over longer tool life, contributing to predictable process times and lower indexable-insert consumption. The round geometry supports smooth cutting transitions, while the 4.76 mm plate thickness provides mechanical stability during interrupted cuts. These characteristics are particularly beneficial where stable chip control and repeatable results are essential for productivity.

System compatibility and mounting clarity

The component is intended for use only in matching Tungaloy milling bodies; insert seat, geometry and cutter body must match technically. The designation 2004M0 and the RFEN form identify the insert family and ensure interchangeability within the correct tool system. The insert is supplied without a hole and without a chipbreaker, so the cutter body and clamping method must be compatible with a plain round insert. The 25° free angle and 0 mm corner radius define the cutting clearance and profile interaction, which should be considered when selecting the tool body and machining parameters to achieve the desired cutting performance.

Typical applications and machining advantages

Engineered for general milling tasks, the insert supports face milling, shoulder milling, slotting, high-feed milling and contouring depending on the assigned tool family. The round insert form is particularly effective where frequent index changes and multi-directional engagement occur; it can extend time between tool changes and reduce set-up complexity. The KS20 compound enhances edge stability, making the insert suitable for operations that require both robust chip formation and acceptable surface integrity. Where process stability and consistent results are priorities, this grade helps maintain throughput while preserving component quality.

Practical considerations for implementation

When integrating the insert into an existing machining process, assess cutting data in relation to the carbide grade and the absence of an integral chipbreaker. Trial runs at conservative cutting speeds and feeds are advisable to determine optimal parameters; the carbide substrate and KS20 grade will then allow gradual adjustment towards productivity targets. Ensure the clamping screw and any available support shim match the cutter body specification to avoid seat mismatches that could affect run-out or clamping force. Proper matching of insert and cutter body reduces the risk of premature wear and supports repeatable, safe machining cycles.
