CNMG 120404 T6215 Wendeplatten - Tungaloy

High wear resistance and consistent edge life combine to deliver steady machining performance for stainless steels; the CVD-coated carbide T6215 and a 0.4 mm corner radius enable controlled chip formation and a fine surface finish. Benefit from the ISO compatibility and rhombic 80° geometry for versatile turning operations. Order the CNMG 120404 T6215 insert directly via Metav Werkzeuge or ask our consultants if needed.

CNMG 120404 T6215 indexable insert for turning — CVD-coated, 80° — Tungaloy

The CNMG 120404 T6215 is an ISO rhombic indexable insert designed for external and internal turning, optimised for machining stainless steels under stable to mildly interrupted cut conditions.

• CVD-coated carbide grade T6215
• 80° rhombic insert with 0.4 mm radius
• Double-sided chipbreaker for controlled chips
• ISO CNMG form with cylindrical hole for secure clamping

Reliable tool life through targeted coating and grade selection

The combination of a CVD-coated surface and a wear-resistant carbide substrate in grade T6215 is engineered to resist the adhesive and abrasive wear commonly encountered when machining stainless steel. This results in predictable tool life under steady cutting conditions, which reduces the frequency of tool changes and stabilises production output. The coating also contributes to a consistent surface finish across batches, supporting tighter part tolerances and less rework. The CNMG 120404 form provides a balanced cutting geometry that suits a broad range of turning tasks without frequent tool reprogramming.

Improved process efficiency via chip control and geometry

The insert’s double-sided chipbreaker and 0.4 mm corner radius are configured to manage chip flow and reduce the risk of entanglement, especially at moderate feeds. The 80° rhombic geometry offers a robust cutting edge and good access for profiling and shoulder turning, while the cylindrical hole ensures secure clamping and repeatable positioning in ISO-compatible holders. Together, these features support higher metal removal rates and fewer interruptions for chip clearing, which contributes directly to lower cycle times and better throughput for batch and serial production.

Simple integration and practical application support

Designed as part of an ISO-based insert system, this indexable plate integrates with standard ISO holders and clamping sets, simplifying inventory and tool changeover. The balanced design fosters controlled chips, less vibration and more stable cutting when paired with an appropriately rigid toolholder and setup. For applications requiring fine-tuning of chipbreaker type or grade selection, Metav Werkzeuge offers application advice to match the insert’s capabilities to the workpiece material and machining stability, helping to lower the overall cost per part through reduced downtime and consistent results.

FAQ

What materials is this insert designed for? The CNMG 120404 T6215 insert is formulated primarily for machining stainless steels; the CVD-coated carbide and T6215 grade provide wear resistance suited to those materials.

Can the insert be used for roughing and finishing operations? Yes, the 80° rhombic geometry and 0.4 mm corner radius offer a balance that accommodates both moderate roughing and fine finishing when matched with suitable feeds and speeds.

Is the insert compatible with standard ISO CNMG holders? The insert follows the ISO CNMG form and secures via a cylindrical hole, making it compatible with ISO CNMG external holders and clamping systems when dimensions and tolerances match.

What role does the double-sided chipbreaker play in machining? The double-sided chipbreaker promotes consistent chip formation and evacuation, improving process stability and reducing the chance of chip-related interruptions during turning operations.

How should the insert be chosen for interrupted cutting conditions? For interrupted cuts, select the T6215 grade with stable clamping and an appropriate chipbreaker; the CNMG 120404 geometry performs well under stable to mildly interrupted conditions but consult machining data for severe interruptions.
