VNMG120402E-PS T9215 — VNMG 120402 ISO turning insert for turning applications (Tungaloy)

The VNMG120402E-PS T9215 is an ISO-standard rhombic turning insert for external and internal turning, featuring a 0° clearance angle, a PS chipbreaker and a CVD-coated carbide grade optimised for medium-steel machining.

• CVD-coated carbide grade T9215
• 0.2 mm corner radius for fine profiles
• ISO rhombic VNMG form, 35° approach angle
• Cylindrical-hole fastening, PS chipbreaker

Improved productivity through wear-resistant CVD coating

The CVD-coated T9215 grade combines high wear resistance with reliable fracture toughness, making it a suitable choice for continuous and lightly interrupted cuts in medium steels. The chemical vapour deposition layer protects the substrate during elevated temperatures and maintains edge integrity over longer tool life. As a result, operators benefit from fewer indexings and more consistent cycle times, which supports higher throughput on conventional and CNC lathes. The wear mechanisms are reduced, preserving surface finish and lowering rework rates.

Precise geometry for repeatable turning results

The rhombic VNMG geometry with a 35° approach provides a balance between cutting-edge strength and access to grooves or shoulders. The 0.2 mm corner radius enables fine profile work while the 4.76 mm plate thickness contributes to rigidity and vibration damping. Compatibility with holders is determined by form, clearance angle, tolerance class, fastening style and thickness; selecting the correct holder and clamping set ensures repeatable accuracy and extends insert life. This insert is supplied with a cylindrical-hole fastening that fits standard ISO-compatible external holders and boring bars.

Chip control and process stability with PS chipbreaker

The integrated PS chipbreaker was designed to promote short, controllable chips under typical medium-steel cutting conditions. Short chips reduce the risk of surface damage and machine stoppages caused by entangled swarf, improving process stability and operator safety. When combined with the T9215 substrate properties, the chipformer helps to maintain stable cutting forces and consistent cutting temperatures, which in turn supports predictable tool wear behaviour and surface quality.

Practical system considerations and application guidance

The insert functions within a system consisting of the ISO insert, a matching external holder or boring bar, a locating pad or clamping set and replacement screws. For best results, choose the chipbreaker and grade according to workpiece material, machining type and machine stability. The grade is particularly well suited for medium-steel applications where a balance of productivity and edge robustness is required. Where interrupted cuts or heavy depths of cut are expected, consider a more robust geometry or a different grade tailored to those conditions.

FAQ

What materials is this insert suitable for?
The VNMG120402E-PS T9215 is optimised for medium steels; the T9215 CVD-coated carbide combines wear resistance and toughness for consistent performance in these materials.

How is holder compatibility determined?
Compatibility depends on insert form, clearance angle, tolerance class, fastening style, size and thickness; the rhombic VNMG form and cylindrical-hole fastening require ISO-compatible holders or boring bars.

What advantages does the PS chipbreaker offer?
The PS chipbreaker promotes short, controllable chips in typical steel turning, improving swarf management, surface protection and process stability during continuous to lightly interrupted cuts.

Can this insert be used for internal turning?
Yes; the geometry and 35° approach angle allow use in both external and internal turning applications when the correct boring bar or holder is selected.

How does the T9215 grade affect tool life?
The CVD-coated T9215 grade increases resistance to abrasive wear while retaining fracture toughness, resulting in longer edge life and more predictable tool-change intervals.
