RDMT1204ZD T3130 RDMT indexable milling insert by Tungaloy

A RDMT1204ZD T3130 indexable insert for milling in Tungaloy systems, designed to provide stable cutting edges and reliable clamping for plan, shoulder, slot, high‑feed and contour milling applications.

• RDMT format 1204ZD, round 12 mm
• Tungaloy T3130 grade for milling
• 15° relief, plate thickness 4.76 mm
• Cylindrical hole with one-sided countersink

Precision and system compatibility that reduces setup risk

The round indexable insert is manufactured from cemented carbide, ensuring dimensional stability and consistent wear behaviour under industrial conditions. As part of a matched Tungaloy milling system, the insert’s RDMT1204ZD geometry and the plate seat on the cutter body must correspond exactly; this compatibility avoids incorrect seating, reduces vibration and preserves the stable cutting edge during interrupted or continuous cuts. The clear system match requirement supports predictable tool life and repeatable component quality.

Grade performance: designed for balanced wear resistance and toughness

The T3130 grade combines resistance to abrasive wear with sufficient toughness to withstand edge loading during heavy engagement cuts. In practice, this means fewer indexings and extended intervals between insert changes, which improves uptime and lowers cost per component. The single‑sided chipbreaker is engineered to control chips at typical feed rates for milling, improving chip evacuation and contributing to a more reliable machining process.

Secure clamping and geometry explained for reliable machining

A cylindrical hole with a one-sided countersink (40°–60°) provides a precise reference and robust clamping area, reducing micro‑movement under cutting forces. The 15° relief (free angle) ensures the correct cutting‑edge engagement while limiting rubbing on the flank, which helps maintain surface finish and reduces thermal loading on the edge. Together, these features deliver secure clamping and consistent tool behaviour across a range of milling tasks.

Practical benefits: process stability and straightforward integration

Using this round insert in the correct tool family supports efficient planing, shoulder and slot milling as well as high‑feed and contour operations where the toolholder and insert geometry are matched. The compact 12 mm diameter and 4.76 mm plate thickness allow straightforward integration into small to medium cutter bodies. Overall, the design focuses on preserving edge integrity, simplifying maintenance and promoting predictable production throughput.

FAQ

Which milling operations suit this insert best?
This insert is intended for plan, shoulder, slot, high‑feed and contour milling when used in compatible Tungaloy milling systems; the RDMT1204ZD geometry supports these operations within the assigned tool family.

What does the T3130 grade offer in practice?
The T3130 grade delivers a balance of wear resistance and toughness, providing stable cutting edges and good stand time for typical milling tasks with the RDMT1204ZD insert.

How does the hole and countersink affect performance?
The cylindrical hole with one‑sided countersink ensures precise seating and secure clamping, reducing micro‑movement and supporting consistent surface quality under varying cutting forces.

Can these inserts be used in non‑Tungaloy holders?
Compatibility depends on exact plate seat geometry and clamping design; the RDMT1204ZD insert requires a matching cutter body and clamping arrangement to ensure safe and reliable operation.
