DNMG150408 T9215 ISO turning insert (DNMG) — Tungaloy, CVD-coated carbide

The DNMG150408 T9215 is an ISO-standard indexable turning insert designed for external and internal turning of medium steels and for continuous to lightly interrupted cuts, featuring a rhombic form with a 55° cutting angle and a 0.8 mm corner radius.

• CVD-coated carbide grade T9215
• Optimised for medium steel turning
• ISO DNMG 150408 geometry for broad fit
• 0.8 mm corner radius, 55° diamond shape

Reliable grade for high productivity and tool life

The CVD-coated T9215 grade combines wear resistance with fracture resistance, making it a reliable choice where consistent productivity is essential. As a CVD-coated carbide insert, it tolerates sustained cutting at production speeds and offers reproducible performance across batches, which helps reduce downtime and tool change frequency. Selecting this grade supports an efficient cost-per-part balance in medium-steel machining without sacrificing process stability.

Geometry and clamping: predictable compatibility for accurate results

The rhombic DNMG form with a 55° cutting angle and a 0.8 mm corner radius gives a predictable balance of strength and edge detail, suitable for finishing and medium-roughing operations. Compatibility with a given holder is determined by the insert form, clearance angle (0°), tolerance class, fastening method and plate thickness (4.76 mm). The presence of a cylindrical hole and double-sided design extends useable edge count while ensuring reliable screw clamping and repeatable seating in standard DNMG cutters.

Chip control and application guidance for consistent surface quality

This insert is fitted with a double-sided chipbreaker engineered for chip formation in medium-steel cutting regimes, aiding evacuation and reducing built-up edge. For continuous to slightly interrupted cuts the grade maintains a stable cutting edge and supports good surface finish; choose the chipbreaker and specific cutting data according to workpiece rigidity and stability. When combined with appropriately rated holders and correct cutting parameters, the system improves throughput and reduces the need for secondary finishing.

Practical notes on selection and use

When specifying inserts, consider holder geometry and the intended operation: external turning, internal turning or profile work will influence the ideal corner radius and chipbreaker selection. The ISO DNMG 150408 format permits straightforward replacement in widely used toolholders, while the T9215 CVD coating extends service life under production conditions. For best results, match grade and chipbreaker to the material and to the stability of the workpiece-fixture system rather than relying solely on maximum cutting speed figures.

FAQ

What materials is this insert suited for?
The DNMG150408 T9215 insert is formulated for medium steels, where the T9215 CVD-coated carbide provides a balance of wear and fracture resistance suitable for productive turning.

How does the T9215 grade perform under interrupted cuts?
T9215 offers good fracture toughness and is appropriate for continuous to slightly interrupted cuts; in heavy interruptions, a grade optimised specifically for high impact resistance should be considered.

Will the insert fit my existing DNMG holder?
The DNMG150408 geometry is ISO-standard, but compatibility depends on holder form, clearance angle, tolerance class, fastening method, size and thickness; ensure the holder matches these parameters for correct seating.

How many cutting edges are available on this insert?
The rhombic, double-sided design of the DNMG150408 allows multiple indexable edges; the exact count depends on the insert orientation and whether both sides are utilised.

What chip control can be expected with this insert?
Equipped with a double-sided chipbreaker, the insert promotes reliable chip formation and evacuation in medium-steel turning, aiding surface finish and process stability.
