WNMG 080404 T6215 — Indexable Turning Insert, TF Chipbreaker, for Turning — Tungaloy

The WNMG080404-TF T6215 is an ISO-format, trigon-shaped indexable insert designed for turning operations, optimised for stainless steels under stable to slightly interrupted cutting conditions.

• CVD-coated cemented carbide grade T6215
• Triangular 80° geometry for versatile turning
• Nose radius 0.4 mm for precise profiles
• With cylindrical mounting hole for secure clamping

Reliable cutting performance for stainless steels

The insert’s CVD-coated cemented carbide substrate delivers high wear resistance and thermal stability, which is particularly valuable when machining stainless steels. The selected T6215 grade is formulated to maintain a stable cutting edge under continuous loads and light interruptions, reducing flank wear and the need for frequent index changes. Given the material characteristics of stainless alloys, the coating’s oxidation resistance and the substrate toughness work together to limit workhardening and improve surface integrity. This results in higher component yield per tool and fewer process interruptions, supporting more efficient production cycles.

Predictable clamping and geometry for repeatable results

Compatibility with toolholders is defined by form, clearance angle, tolerance class, fastening method, size and thickness; accordingly, the trigon shape with an 80° included angle and 0° clearance provides a balance between edge strength and accessibility. The insert’s cylindrical mounting hole enables secure, repeatable clamping, while the 4.76 mm thickness contributes to rigidity during heavier cuts. These geometric characteristics ensure consistent tool positioning and repeatable part tolerances across batches. Compatibility is determined by the holder design and the insert’s nominal dimensions, so matching the ISO code 080404 and the plate size 08 with the appropriate seat and screw guarantees stable cutting conditions.

Process guidance: chip control and profile accuracy

The TF chipbreaker is tailored for the grade and application, promoting controlled chip formation when turning stainless steels under steady conditions. The nose radius 0.4 mm offers a compromise between profile definition and edge strength: it produces good surface finish while maintaining resistance to chipping in semi-finishing and finishing passes. For industrial practice, combine the insert with a matching external holder or boring bar, correct clamping torque and suitable cutting parameters adapted to material and machine rigidity. The insert forms part of a system comprising the ISO indexable plate, the mounting pad or clamping set, and replacement screws; together they enable predictable performance and straightforward maintenance of process settings.

FAQ

What materials is this insert best suited for?
The insert is optimised for machining stainless steels; the T6215 CVD-coated cemented carbide grade provides wear resistance and edge stability for those alloys.

How does the TF chipbreaker affect machining?
The TF chipbreaker promotes controlled chip formation for steady cutting, improving surface quality and reducing the risk of built-up edge during turning operations.

Which dimensions ensure holder compatibility?
Compatibility is determined by form, clearance angle, tolerance class, fastening, size and thickness; match the ISO code 080404, plate size 08 and thickness 4.76 mm with the appropriate holder seat.

What surface finish can be expected with a 0.4 mm nose radius?
A 0.4 mm nose radius balances profile accuracy and edge strength, typically yielding good surface finishes in semi‑finishing and finishing passes while maintaining resistance to chipping.

Is the insert supplied ready for mounting?
The insert comes in the ISO format and is intended to be used with the correct holder, mounting pad or clamping set and replacement screws to secure it for turning operations.
