DNMG 150412 T9215 — Turning insert by Tungaloy (CVD-coated carbide, 55°)

The DNMG150412 T9215 Tungaloy insert is an ISO-indexable turning insert designed for medium steel machining and suited to both external and internal turning applications.

ISO-indexable rhombic DNMG insert T9215 CVD-coated carbide grade Double-sided chipbreaker for medium steel 1.2 mm corner radius with 55° angle

High productivity with consistent wear resistance

The CVD-coated carbide grade T9215 combines elevated wear resistance with fracture toughness, making this indexable cutting geometry ideal for medium steel turning under continuous to lightly interrupted cuts. The coating enhances tool life by resisting abrasive wear, while the substrate maintains edge strength. As a result, machining cycles run longer between indexings, reducing downtime and contributing to a more predictable production rhythm. This balance of hardness and toughness supports higher cutting speeds where process stability is required.

Precise geometry for controlled chip formation and surface finish

The rhombic form with a 1.2 mm corner radius and double-sided chipbreaker provides reliable chip control and a consistent surface quality on turned components. The corner radius increases the effective cutting edge cross-section, improving resistance to chipping, while the chipbreaker geometry shapes swarf for safer evacuation. For users less familiar with insert nomenclature: the corner radius affects both finish and strength—larger radii improve edge robustness but can slightly increase cutting forces; the chosen radius here supports a strong compromise between finish and durability.

Designed for ISO-system compatibility and easy integration

Compatibility with holders is governed by factors such as form, relief angle, tolerance class, fastening method, size and thickness; the insert fits ISO-standard tools when those parameters match. Typical system build comprises the ISO-indexable plate, a matched external holder or boring bar, an underlay/clamp set and replacement screws as required. This approach enables quick index changes and straightforward spare-part management on the shop floor, reducing setup time and helping to maintain throughput on multi-shift production lines.

Application focus and recommended use

Engineered specifically for turning, the grade performs best in medium steel machining, offering productive cutting in continuous and lightly interrupted operations. The durable substrate and CVD coating make it suitable where a stable process and consistent part tolerances are priorities. Choose the double-sided configuration to maximise usable edges per insert; select a matching chipbreaker and grade with regard to workpiece material, machining strategy and fixture stability to unlock the full benefit of the insert.

FAQ

What materials is this insert best suited for? The DNMG150412 T9215 insert is optimised for medium steel machining; the T9215 CVD-coated carbide is selected to balance wear resistance and toughness for productive turning.

How does the 1.2 mm corner radius affect performance? A 1.2 mm corner radius increases edge strength and improves resistance to chipping, helping to maintain surface finish and extend the interval between indexings when using the DNMG insert.

Is the insert compatible with standard ISO holders? Compatibility depends on matching form, relief angle, tolerance class, fastening method, size and thickness; when holders meet these ISO parameters, the insert integrates into standard turning systems.

Can this insert be used for interrupted cuts? The T9215 grade and the insert geometry are suitable for continuous to lightly interrupted cuts; more severe interruptions require evaluation of fixture stability and cutting conditions.

What chip control can be expected from the chipbreaker? The double-sided chipbreaker delivers consistent swarf formation and evacuation, supporting safer machining and stable surface quality in turning operations using this indexable insert.
