CNMA090408 T515 indexable insert for turning by Tungaloy — CVD-coated carbide, 80° geometry

CNMA090408 T515 is an ISO‑normed turning insert designed for efficient machining of cast iron; the rhombic shape and cylindrical hole ensure secure clamping in standard holders.

• CVD-coated carbide for cast iron machining
• 80° rhombic geometry for stable cutting
• 0.8 mm corner radius for increased edge strength
• No chipbreaker for continuous cutting conditions

Consistent, economical cutting performance for cast iron

The CVD-coated carbide grade T515 combines wear resistance with attractive cost-efficiency, enabling economical machining of cast iron components. The coating promotes stable chip formation and extends tool life, which reduces tool changes and machine downtime. Compatibility with ISO toolholders is governed by form, clearance, tolerance class, fixing method, size and thickness; this standardisation simplifies tool inventory and supports reproducible process results. The rhombic geometry and 80° included angle provide a reliable compromise between cutting edge strength and access to profiles.

Secure clamping and reliable surface quality in turning operations

The insert’s cylindrical hole and defined tolerance ensure positive location and clamping force in compatible holders, yielding repeatable cutting geometry and consistent surface finish. A 0° clearance angle supports full-face engagement where required, while the 0.8 mm corner radius balances edge robustness with the ability to achieve the required workpiece contours. Where stability and interrupted cuts are a concern, choose an appropriate holder and feed rate to preserve edge life; the plate’s ISO geometry eases selection of matching toolblocks and boring bars.

Application guidance for productive machining results

Designed for external and internal turning, this insert performs best in stable setups and continuous cutting; the absence of an integrated chipbreaker means its strengths lie in steady material removal rather than aggressive chip control in highly interrupted cuts. For cast iron workpieces, select cutting data that reflect machine rigidity and workpiece support to exploit the insert’s T515 wear characteristics. Metav Werkzeuge can advise on holder matches, clamping sets and replacement screws within the defined ISO system to ensure rapid integration into production and predictable output.

FAQ

What materials is this insert best suited for?
The CNMA090408 T515 insert is optimised for machining cast iron; the T515 CVD coating supports stable chip formation and extended tool life when turning such materials.

Which toolholders are compatible with this insert?
Compatibility is determined by the ISO geometry (CNMA 09 04 08), form, clearance angle and thickness; use holders and boring bars specified for ISO CNMA inserts and match the 80° rhombic configuration.

Does the insert include a chipbreaker?
This grade is supplied without a chipbreaker, so it is intended for continuous turning conditions; for heavy interruptions, consider inserts with dedicated chip control geometries.

How does the 0.8 mm corner radius affect cutting performance?
A 0.8 mm corner radius increases edge strength and resistance to chipping while maintaining an acceptable surface finish for many turning tasks, offering a balance between durability and profile accuracy.

Can Metav Werkzeuge supply matching clamping sets and screws?
Metav Werkzeuge can advise on and supply the correct underplates, clamping sets and replacement screws to ensure secure mounting and repeatable results with this Tungaloy insert.
