DNMG150408 T9215 indexable turning insert — CVD-coated carbide, rhombic 55° by Tungaloy

The DNMG150408 T9215 is an ISO-standard rhombic insert designed for external and internal turning, offering a balance of wear resistance and toughness for medium-stiff steel machining.

• ISO rhombic insert, 55° geometry
• CVD-coated carbide grade T9215
• 0.8 mm corner radius for versatile finishes
• Double-sided insert with cylindrical hole

High productivity through a wear-resistant grade

The CVD-coated carbide grade T9215 combines improved sliding properties with structural durability, which makes it a reliable choice for medium steel applications. This coating supports extended tool life by increasing wear resistance while the substrate maintains fracture toughness, so machining can proceed at higher material removal rates with fewer indexings. The result is a measurable uplift in productivity for continuous to slightly interrupted turns, with more consistent tool performance over longer production runs.

Geometry and clamping for repeatable accuracy

The rhombic ISO form with a 55° main cutting angle and a clearance angle of 0° is optimised for general turning tasks; the 0.8 mm corner radius delivers a compromise between robustness and surface finish. With a plate thickness of 4.76 mm and a nominal size of 15 mm, the insert interfaces via a cylindrical hole that supports secure, repeatable clamping. Compatibility with the chosen holder depends on form, free angle, tolerance class, fastening method, size and thickness, and correct pairing reduces vibration and improves both dimensional control and tool life.

Practical benefits for workshop operations

The insert delivers improved chip control and predictable cutting behaviour when used with an appropriate chipbreaker and holder system, reducing manual rework and inspection time. The geometry and coating combination contribute to a consistent surface finish and fewer interruptions for tool change. For shops prioritising steady production and process reliability, the DNMG150408 T9215 insert offers a cost-effective path to repeatable results while maintaining operational uptime through durable performance.

FAQ

What materials is this insert suited for? The CVD-coated grade T9215 is primarily intended for medium steel machining and provides a good balance of wear resistance and toughness for productive turning operations.

How does the plate geometry affect performance? The rhombic 55° geometry combined with a 0.8 mm corner radius offers robustness for general turning while enabling acceptable surface finish and stable cutting forces for a range of turning tasks.

Is the insert compatible with standard ISO holders? Compatibility is determined by holder form, free angle, tolerance class, fastening and the insert’s size and thickness; matching these parameters ensures correct seating and repeatable clamping of the insert.

Can this insert handle interrupted cuts? The grade and substrate toughness make it suitable for continuous to slightly interrupted cuts; severely interrupted or highly unstable conditions may require a more fracture-resistant geometry or different grade.
