DNMG 150408 T515 turning insert — Tungaloy

The DNMG150408 T515 Tungaloy insert is an ISO-standard indexable turning insert engineered for efficient, economical machining of cast iron in both external and internal turning operations.

• CVD-coated T515 for cast iron
• Rhombic 55° geometry for stable cutting
• Double-sided chipbreaker with cylindrical hole
• 0.8 mm corner radius and 4.76 mm thickness

Productive turning for cast iron components

The combination of a CVD coating and a wear-resistant carbide substrate delivers stable performance when machining cast iron, where controlled chip formation is essential. The T515 grade is tuned for cost-effective cycles, providing a balance between tool life and cutting speed that supports efficient batch and serial production. By selecting the appropriate chipbreaker and cutting parameters, machinists can reduce downtime and improve surface consistency without sacrificing productivity.

Geometry that ensures repeatable results

The rhombic 55° geometry and the ISO-standard form allow predictable engagement with a wide range of holders; compatibility depends on form, clearance angle, tolerance class, fastening method, size and thickness. The 0° clearance and the standardised shape contribute to consistent cutting forces and straightforward tool setup, which simplifies process planning and reduces the need for frequent re‑adjustment when changing inserts.

Durability and economical edge usage

A double-sided design provides two usable cutting edges per face, halving the cost per edge compared with single-sided inserts. The CVD-coated T515 finish improves resistance against abrasive wear typical of cast-iron machining, extending intervals between indexings. For operations with intermittent cuts or varying stability, the robust coating and substrate combination supports repeatable performance across shifts and job changes.

Practical integration into standard tooling systems

The insert is supplied with a cylindrical hole, enabling secure clamping with common screw and clamp systems; thickness of 4.76 mm and a 15 mm inscribed circle suit many ISO holders. The 0.8 mm corner radius provides a compromise between edge strength and achievable surface finish, useful for applications that require both durability and acceptable geometry of the turned profile. The ISO-series architecture means the item integrates into established tool assemblies—insert, appropriate external holder or boring bar, and shim/clamp—so workshop implementation is straightforward.

FAQ

What materials is this insert suitable for?
The DNMG150408 T515 insert by Tungaloy is designed primarily for cast iron machining, with the CVD-coated T515 grade optimised for economic performance on these materials.

How does the double-sided design affect cost-efficiency?
Because the insert is double-sided, each indexable face offers multiple cutting edges; this reduces cost per edge and improves the overall economy of using the Tungaloy carbide insert (SKU 6754109-Tungaloy).

Which holders are compatible with this ISO insert?
Compatibility depends on holder form, clearance, tolerance class, fastening and thickness; the DNMG150408 conforms to ISO geometry and fits standard external holders and boring bars designed for rhombic 55° inserts.

Can this insert be used for interrupted cuts?
Yes, the robust carbide substrate and CVD coating of the T515 grade make the insert suitable for applications with intermittent cuts, though selection of chipbreaker and cutting parameters should reflect stability and severity of interruption.

What are the key dimensional features to check when replacing inserts?
Check the inscribed circle (15 mm), thickness (4.76 mm), corner radius (0.8 mm) and hole style (cylindrical) to ensure proper fit and clamping in the chosen holder.
