WNMG 080408 T515 — ISO turning insert, 80° trigon, Tungaloy

The WNMG080408 T515 is an ISO-standard trigon turning insert engineered for efficient external and internal turning, optimised for economical cast iron machining.

• ISO trigon 80° geometry
• CVD-coated carbide grade T515
• Double-sided chipbreaker
• 0.8 mm nose radius

Economical performance for cast iron turning

The combination of a CVD-coated surface layer and a wear-resistant carbide substrate delivers sustained tool life when machining cast iron. The T515 grade is formulated to balance hardness and toughness, which supports higher cutting speeds without excessive wear. In practical terms, this translates to fewer insert changes and longer productive runs on batch operations, improving overall process economy. The reliable coating reduces built-up edge formation and helps maintain dimensional accuracy across extended shifts.

Geometry that stabilises surface finish and chip flow

An 80° trigon geometry with a 0.8 mm nose radius provides a compromise between strength at the cutting edge and the ability to achieve consistent surface quality. The double-sided chipbreaker promotes predictable chip control in both light and medium cuts, lowering the risk of chip clogging and reducing cycle interruptions. For operations with moderate rigidity, this geometry helps sustain feed rates while preserving component tolerances and reducing subsequent finishing effort.

Holder compatibility and secure clamping for process stability

Compatibility with toolholders depends on form, clearance angle, tolerance class, fastening method, size and plate thickness; the standardised dimensions ensure interchangeability across ISO-compliant clamping systems. The trigon plate with a cylindrical hole and 4.76 mm thickness permits secure fastening in indexable holders and boring bars, while the 0° clearance angle supports positive engagement for stable cutting. Correct seating and torqueing of the attachment screw preserve repeatability and contribute to consistent part quality.

Recommended use and process guidance

Designed primarily for turning, both external and internal, the insert is suitable where cast iron is the predominant workpiece material and where interrupted cuts or varying stiffness are encountered. Selection of the T515 grade should be matched to machine power and fixture rigidity: higher stability enables higher speeds, while less rigid setups benefit from conservative feeds. The ISO series construction allows quick re-indexing of the insert to exploit the double-sided design and reduce tooling costs per component.

FAQ

Which materials are best suited for this insert?
The WNMG080408 T515 is optimised for cast iron workpieces; the T515 grade with a CVD-coated carbide surface provides good wear resistance and chip control when machining grey and nodular cast irons.

Is the insert compatible with standard ISO holders?
Yes, the insert uses ISO-standard geometry and dimensions; compatibility is ensured by matching form, clearance angle, tolerance class, fastening and size to the clamping system.

Can the insert be re-indexed to extend life?
The trigon design is double-sided, allowing multiple cutting edges per insert to be used sequentially and reducing tooling cost per part.

What edge preparation and cutting data are recommended?
Edge selection should consider part rigidity and cut conditions; the 0.8 mm radius balances finish and edge strength—conservative feeds for unstable setups and increased speeds for rigid conditions are advised.

Does the insert suit interrupted cuts?
The T515 grade and robust trigon geometry offer good performance under interrupted cutting, provided holder and workpiece fixturing supply sufficient stability.
