SNGN 120412 TZ120 Wendeplatten - Tungaloy

Benefit from the combination of TZ120 carbide grade's wear resistance and edge stability, the ISO SNGN form for straightforward holder compatibility, and a robust 90° geometry with a 1.2 mm corner radius for reliable turning performance; order directly via Metav Werkzeuge or consult the technical advisers for application-specific guidance.

SNGN 120412 TZ120 — ISO turning insert, square 12 mm, 90°

SNGN120412 TZ120 is an ISO‑standard square indexable insert designed for precision external and internal turning; the insert combines a cemented carbide substrate with the TZ120 grade to balance wear resistance and toughness.

ISO SNGN form for wide holder compatibility
TZ120 carbide grade with high wear resistance
90° geometry for strong corner support
1.2 mm corner radius for robust turning

Engineered for consistent machining and longer tool life

The TZ120 cutting grade, combined with a cemented carbide substrate, provides a focused balance of wear resistance and edge stability that supports reliable production runs. This balance reduces unexpected tool-wear variability and contributes to predictable component quality, thereby supporting process efficiency and lower rework rates. The insert's engineered geometry aims to maintain a stable cutting edge under moderate to demanding turning conditions, translating technical properties into measurable productivity benefits.

Seamless integration with ISO tooling systems

The insert follows ISO specifications for the SNGN family, so compatibility with holders is governed by the insert's form, clearance angle (0°), tolerance class, clamping method, size and thickness. The standardised design simplifies inventory management and ensures repeatable locating and clamping in compatible toolholders. For production settings that require quick insert changes and consistent seating, the ISO designation facilitates tool‑system planning and reduces setup time while maintaining machining accuracy.

Application flexibility and advantages in turning operations

Designed for both external and internal turning, the square SNGN geometry and 90° corner configuration deliver sturdy support for heavier cutting engagement while the 1.2 mm corner radius helps to preserve corner integrity during interrupted cuts. The insert is supplied without a chipbreaker, offering the option to match chip control strategies to the specific workpiece material and stability of the machining setup. Where a chipformer or a different edge preparation is required, selection of a suitable chipbreaker and matching grade will tailor the cutting performance to the application and stability demands. The use of a robust carbide grade underpins repeatable surface finish and dimensional consistency in component production.
