RDKN 2004TN AH120 indexable insert for milling by Tungaloy — PVD-coated carbide, round 20 mm

The RDKN2004TN AH120 is a round indexable insert designed for Tungaloy milling systems, suitable for face, shoulder, slot, high-feed and contour milling when paired with matching cutters

• PVD-coated carbide for extended tool life
• Sharp cutting edge for reliable process security
• Round 20 mm insert, 4.76 mm thickness
• 15° clearance angle, without hole

High-performance coating and substrate for steady production

The combination of PVD coating and a carbide substrate delivers a balanced resistance to wear and thermal loading, ensuring stable cutting over longer intervals. The applied coating reduces adhesion of built-up edge and improves surface quality on workpieces, which translates directly into fewer component reworks and more predictable cycle times. This technical pairing is particularly effective when high cutting speeds are required or when the process demands a consistently sharp edge and process security.

Geometry engineered for rigidity and repeatable results

The insert’s round form with a 20 mm diameter and 4.76 mm thickness offers a compact contact area that supports robust clamping and vibration damping during milling. The 15° clearance angle provides effective shear formation while protecting the cutting edge from premature chipping. These geometric factors combine to increase tool life and maintain reproducible dimensional accuracy across serial production, reducing scrap and improving first-pass yield.

Versatility across common milling operations

Designed for multiple milling tasks, this indexable plate performs well in face milling, shoulder operations, slotting and higher-feed strategies when used within the appropriate Tungaloy cutter family. The grade AH120 is specified as a wear- and fracture-resistant option, making the insert a dependable choice where a sharp cutting edge and secure process behaviour are both required. Selecting this grade helps broaden the material range that can be machined effectively without frequent tool changes.

Practical benefits: uptime, tool management and process safety

Using a high-stability insert reduces unplanned stoppages and simplifies tool management. The consistent wear characteristics of the grade enable better prediction of tool-change intervals and easier integration into maintenance schedules. Fewer edge failures mean less intervention on the shop floor and improved operator confidence in daily production. Combined with appropriate cutter bodies and correct seating, the insert contributes to a measurable increase in productivity and lower manufacturing overhead.

FAQ

Is this insert compatible with standard Tungaloy milling bodies?
Yes. The RDKN2004TN AH120 insert is intended for use in Tungaloy milling systems; ensure the cutter body, seat geometry and clamping screw correspond to the insert designation and size.

Which materials can be machined with this grade?
The AH120 grade on the RDKN2004TN is optimised for wear and fracture resistance and suits a broad range of materials commonly encountered in milling operations when used with appropriate cutting parameters.

Does the insert have a chipbreaker?
No, this particular insert is supplied without a chipbreaker; its round geometry and edge preparation are intended for stable chip formation in the specified milling strategies.

What is the manufacturer article number and SKU for ordering?
The manufacturer article number is 6805880 and the manufacturer SKU is TUN6805880; both identifiers relate to the RDKN2004TN AH120 indexable insert by Tungaloy.

How does the 15° clearance angle affect cutting performance?
A 15° clearance angle balances shear formation and edge protection, supporting a sharp cutting action while reducing the risk of edge chipping under moderate to demanding milling loads.
