WNMA 080408 T515 WNMA indexable insert for turning — Tungaloy

WNMA080408 T515 is an ISO-format indexable turning insert designed for efficient external and internal turning, optimised for the economical machining of cast iron.

• CVD-coated carbide grade T515 for cast iron
• ISO WNMA080408 trigon insert with hole
• 0.8 mm corner radius for robust edge strength
• Compatible with standard ISO turning holders

Efficient machining with an economical CVD-coated grade

The combination of a CVD-coated surface and carbide substrate in grade T515 delivers extended tool life and consistent cutting-edge resistance when turning cast iron. The coating reduces flank and crater wear, which in turn supports higher sustained cutting speeds and fewer insert changes — a clear benefit for batch production and continuous operation. For production managers this translates into lower tool consumption and more predictable process windows.

Secure ISO fitment for consistent process accuracy

Manufactured to ISO dimensions, the trigon geometry with a central cylindrical hole ensures reproducible seating and clamping in compatible holders. Compatibility depends on the insert form, clearance angle, tolerance class, fixing method, size and thickness; adherence to ISO standards helps to avoid misalignment and vibration. As a result, the setup yields repeatable part geometry and surface finish without extensive fixture modification.

Edge geometry designed for stability in interrupted cuts

A 0.8 mm corner radius combined with an 80° insert form provides a robust cutting edge that withstands moderate shock loads and interrupted cuts. The insert features a 0° clearance angle and is supplied without a chipbreaker, which makes it suitable where chip control is managed externally or when fine-tuning cutting data for specific cast-iron grades. The geometry supports stable cutting forces and reduces the risk of premature edge chipping during heavy engagement.

Simple integration into turning systems and material coverage

The insert is part of an ISO turning-system that comprises the insert itself, the matching external holder or boring bar, and standard clamping hardware such as a support pad and fastening screw. Selection of an appropriate chipbreaker and holder stiffness should reflect workpiece material, machining type and expected stability. The grade is primarily aimed at cast iron, offering a broad suitability for typical foundry and finishing operations while enabling predictable tool life and surface quality.

FAQ

What materials is this insert intended for?
The WNMA080408 T515 indexable insert from Tungaloy is intended primarily for economical machining of cast iron, the T515 grade offering wear resistance suitable for this material group.

How is the insert fixed in the holder?
Fixing uses the central cylindrical hole combined with standard ISO clamping methods; the ISO-format dimensions and tolerance ensure stable seating in compatible turning holders and boring bars.

Can the insert handle interrupted cuts?
Yes — the 0.8 mm corner radius and robust edge geometry make it resilient to interruptions, although the insert is supplied without a chipbreaker so chip control may need to be managed via cutting data or an appropriate holder/chip control solution.

Which insert geometry and size should be ordered?
This insert is the ISO WNMA080408 format: trigon form, size 08, 80° insert angle and 0.8 mm corner radius; reference the SKU 6733843-Tungaloy or article number 6733843 when ordering.
