WNMG 080408 T9215 — ISO trigon turning insert, CVD-coated cemented carbide (Tungaloy)

A WNMG 080408 T9215 is an ISO-standard trigon indexable insert designed for external and internal turning, providing high productivity on medium steel with a dedicated chipbreaker for stable cutting.

• CVD-coated cemented carbide T9215
• Optimised for medium steel machining
• Trigon shape with 0.8 mm corner radius
• ISO compatibility with cylindrical locate hole

Consistent productivity with CVD-coated T9215

The CVD-coated cemented carbide grade T9215 is formulated to balance wear resistance and fracture toughness, making it well suited for continuous and lightly interrupted turning of medium-strength steels. The coating reduces flank and crater wear, extending tool life and reducing changeover frequency. For production environments where cycle time and uptime matter, this indexable insert delivers repeatable performance and helps to keep machining costs predictable through fewer tool changes and consistent surface quality.

Geometry and ISO conformity for reliable clamping

The trigon shape and ISO designation ensure the insert fits a wide range of standard external and internal holders when the holder matches the form, relief angle, tolerance class, fastening method, size and thickness. The 0.8 mm corner radius contributes to improved edge robustness and better surface finish under moderate feeds, while the 0° relief and 80° included angle help transfer cutting forces into stable contact with the toolholder. The cylindrical locate hole facilitates positive locating and secure fastening, supporting repeatable indexing and minimising setup variation.

Chip control and stable cutting in practical use

The integrated chipbreaker 37 is tuned for efficient chip formation on steel grades, promoting short, curl-controlled chips that evacuate reliably in typical turning scenarios. The combination of chip geometry and the T9215 material behaviour reduces the risk of built-up edge and unexpected breakouts during semi-continuous cuts. When paired with suitable cutting parameters, the insert supports higher metal removal rates and consistent part tolerances, making it a practical choice for batch production and single-piece flows alike.

Handling, selection and machining recommendations

Mount the insert in a holder compatible with ISO trigon inserts and confirm clamping surfaces are clean and free of burrs; secure seating assures the designed chipflow and coating performance. For initial trials on medium steel, start with conservative speeds and feeds and increase in controlled steps while monitoring tool wear and surface finish. Where intermittent cuts occur, the grade’s fracture resistance helps maintain integrity; for heavily interrupted cuts consider alternative geometries. For detailed feed and speed guidance or holder compatibility, Metav Werkzeuge can provide tailored recommendations to suit specific machine and workpiece conditions.

FAQ

What material range is this insert designed for? The insert in T9215 grade is designed primarily for medium steel applications and provides a balance of wear resistance and toughness for productive turning.

Which holders are compatible with the trigon form? Compatibility depends on the holder matching the ISO form, relief angle, tolerance class, fastening method, size and thickness; the trigon shape with cylindrical hole suits ISO-standard holders designed for this form.

How does chipbreaker 37 affect machining? Chipbreaker 37 promotes short, controlled chip formation on steel, improving evacuation and reducing the chance of entangling chips during continuous or lightly interrupted cuts.

Is the insert suitable for interrupted cuts? The CVD-coated, fracture-tough T9215 grade tolerates light interruptions well; for heavy interruptions, consider geometries and grades specifically optimised for high-impact conditions.

What information is needed to select the correct insert for a job? Provide workpiece material, turning operation (external or internal), machine power/stability, and expected cut interruption; this allows selection of the correct insert geometry, chipbreaker and grade for the application.
