RFEN 2004ZF KS20 – indexable insert for milling (Tungaloy)

RFEN2004ZF KS20 is an indexable insert designed for use within Tungaloy milling systems; intended for face, shoulder, slot, high-feed and contour milling depending on the assigned cutter body.

• Carbide grade KS20 for milling stability
• 25° relief angle for controlled cutting
• Round insert, 20 mm diameter
• 4.76 mm thickness, no hole

Consistent results for high-productivity milling

The carbide composition and geometry deliver a balance of wear resistance and edge stability that supports continuous production. With the KS20 grade matched to the insert geometry, the tool life becomes more predictable and tool-changing intervals lengthen, which reduces machine downtime. This attribute is particularly valuable for repetitive tasks such as face and shoulder milling where consistent dimensional results and surface finish matter. The design emphasises repeatable performance over many indexings, helping to maintain cycle-time targets and stable process output.

Extended service life through an optimised grade

The KS20 cutting grade is selected to provide a compromise between hardness and toughness: enhanced wear resistance combined with sufficient fracture resistance for interrupted cuts or mixed materials. This leads to fewer edge failures and improved overall economy per cutting edge. The resulting lower frequency of insert changes supports a more economical production rhythm and contributes to predictable consumable consumption in the tool inventory. Where surface integrity and repeatability are priorities, the grade’s performance characteristics deliver measurable gains.

Secure clamping and predictable chip behaviour

Designed as a system component, the insert matches Tungaloy cutter pockets and fastening methods so that seat fit, geometry and clamping achieve the intended cutting kinematics. The round shape and specified relief angle of 25° provide stable contact and controlled engagement, reducing vibration and improving surface consistency on workpieces. The version supplied here has no central hole and no integral chipbreaker, which is appropriate where the cutter body provides chip control; this simplifies matching the insert to the correct holder and avoids unexpected fitment issues.

Clear selection and straightforward integration

Technical specifications such as 4.76 mm thickness, 20 mm size and the ISO designation support rapid selection during tool planning. The insert is intended for mounting in the designated Tungaloy milling bodies; correct pairing ensures intended cutting forces and heat distribution. For operations spanning planing, slotting or contouring, this insert offers a reliable option that integrates into existing milling families. Technical staff will appreciate the concise specification for process planning and spare-part stocking.

FAQ

What materials is this insert intended to machine?
The RFEN2004ZF KS20 insert is designed for general milling applications; the KS20 grade offers a balance suitable for a broad range of steels and mixed materials as specified for Tungaloy milling grades.

How is the insert mounted in the milling cutter?
This round insert is intended to be clamped in compatible Tungaloy milling bodies; seat geometry and clamping must match the insert shape and ISO designation for secure fit and correct cutting alignment.

Does the insert include a chipbreaker or central hole?
The RFEN2004ZF KS20 is supplied without a hole and without an integrated chipbreaker; chip control is achieved via the cutter body or the selected tool family.

Which ISO designation corresponds to this insert?
The ISO code for this indexable insert is 2004ZF, which should be used when verifying compatible cutter bodies and ordering matching inserts.
