CNGN120712 TS200 – Turning indexable insert by Tungaloy

The CNGN120712 TS200 is a rhombic, ISO-designated turning indexable insert designed for external and internal turning tasks across a wide range of materials.

• ISO rhombic insert CNGN 120712
• Tungaloy TS200 grade for wear resistance
• 1.2 mm corner radius, 0° clearance

Higher uptime through a wear‑resistant grade

The TS200 grade is a Tungaloy-developed carbide combination that emphasises wear resistance while retaining sufficient toughness for interrupted or semi-stable cuts. In practice, this balance reduces flank wear and extends tool life compared with softer grades, which translates into fewer insert changes and higher machine availability. For production environments where consistent surface finish and repeatable tool life are priorities, the combination of carbide substrate and the TS200 coating characteristics supports stable chip formation and predictable regrinding cycles.

Secure seating and repeatable set‑ups for faster changeovers

Built to the ISO series dimensions, the geometry of this rhombic insert ensures compatibility with standard turning holders; important matching criteria include form, relief angle, tolerance class, attachment method, size and thickness. The specified 0° clearance and the 80° included angle provide a neutral machining geometry that helps achieve steady contact conditions in many turning set-ups. Because the insert conforms to ISO tolerances, clamping repeatability is improved and set-up time is reduced, which benefits batch production and mixed‑batch workflows.

Practical machining scope and handling recommendations

The holeless, rhombic design and a 1.2 mm corner radius make the insert versatile for medium feeds where edge strength matters without sacrificing contour fidelity. With a plate thickness of 7.94 mm the insert maintains rigidity under axial and radial loads, while the absence of a chipbreaker means the chip control strategy should be selected according to workpiece material and cutting conditions. Suitable for both external and internal turning, the insert works well when paired with a matching holder or boring bar and the correct clamp/shim set, forming a complete system that supports productive machining.

FAQ

What materials is this insert suitable for?
The CNGN120712 TS200 insert is designed as a versatile turning tool; the TS200 grade provides broad material coverage and is suitable for many steels and alloyed materials where wear resistance is required.

How does the 1.2 mm corner radius affect performance?
A 1.2 mm corner radius increases edge strength compared with smaller radii, improving resistance to chipping while still allowing acceptable surface finish in general turning applications.

Is the insert compatible with standard ISO holders?
Yes, the insert follows ISO dimensions (CNGN 120712), so compatibility with standard turning holders is determined by form, relief angle, tolerance class, attachment, size and thickness.

Why is there no chipbreaker specified?
This version is supplied without a chipbreaker to allow selection of the most appropriate chip control strategy for the workpiece material and cutting conditions; the absence of a chipbreaker can be advantageous in applications requiring specific chip shapes.

How to order the genuine Tungaloy insert and which SKU to reference?
Refer to article number 6311051 or manufacturer SKU TUN6311051 when ordering genuine Tungaloy turning inserts; Metav Werkzeuge can assist with selection and supply.
