CNMG 190612 T9215 Wendeplatten - Tungaloy

Take advantage of the combination of CVD-coated carbide (T9215) wear resistance, a 1.2 mm corner radius for robust finishes, and double-sided indexing for lower cost per edge — order the CNMG190612 T9215 turning insert directly via Metav Werkzeuge or ask our consultants if needed.

CNMG 190612 T9215 indexable turning insert (ISO CNMG, 19 mm, 80°) — Tungaloy

The CNMG190612 T9215 is an ISO rhombic indexable insert for turning, optimised for medium steel machining and designed for productive continuous to slightly interrupted cuts.

• ISO rhombic CNMG form, 80° included angle
• CVD-coated carbide grade T9215
• Corner radius 1.2 mm for robust finishes
• Cylindrical hole, double-sided insert

High-performance grade for reliable medium-steel turning

The insert uses a CVD-coated carbide (T9215) grade that balances wear resistance with fracture toughness, making it a dependable choice for sustained production. The coating extends edge life under the thermal and mechanical loads typical of medium-steel turning, so fewer tool changes are required. This technical combination supports a higher throughput while maintaining dimensional stability and surface quality in serial and batch production.

Geometry that combines strength and surface result

The ISO rhombic CNMG geometry with an 80° included angle and a corner radius 1.2 mm offers a compromise between edge strength and surface finish. The 19 mm size and 6.35 mm thickness provide a stable cutting edge, while the 0° relief angle suits general-purpose external and internal turning. The double-sided configuration delivers two usable cutting edges per face, improving cost-efficiency by reducing cost per cutting edge and extending service intervals.

Secure clamping and system compatibility for predictable results

The insert is supplied with a cylindrical hole for positive location in the seat and is compatible with standard CNMG holders and boring bars when matched by form, relief angle, tolerance class, clamping method, size and thickness. Correct selection of the mating toolholder, shim/retainer and fastening screw is essential for repeatable performance; the system approach ensures consistent chip formation and vibration control during operation.

Practical selection advice for production efficiency

Choose a chipbreaker and grade that match the workpiece and cutting conditions: the T9215 grade is the recommended first choice for medium-steel applications where high productivity and reliable edge life are priorities. In continuous or lightly interrupted cuts the insert delivers good process stability and predictable tool life, while indexing to a fresh edge reduces downtime. For special materials or severer interruptions, select an alternative chipformer or a grade tailored to the application.

FAQ

Which materials is this insert intended for?
The CNMG190612 T9215 insert from Tungaloy is optimised for medium steel machining and performs best in continuous to slightly interrupted turning operations on these materials.

How many usable edges are available per insert?
The CNMG indexable turning insert is double-sided, offering multiple usable edges which increases cost-efficiency per cutting edge.

What does the 1.2 mm corner radius influence?
A corner radius of 1.2 mm improves edge strength and contributes to a robust surface finish, making the insert suitable for stable turning where both durability and reasonable surface quality are required.

Is the insert compatible with standard CNMG holders?
Compatibility depends on holder form, relief angle, tolerance class, clamping method, size and thickness; when these parameters match the insert specification, standard CNMG holders and boring bars can be used.

What fastening/clamping style does the insert use?
The insert features a cylindrical hole for secure location and clamping in compatible toolholders, ensuring repeatable positioning and stable cutting behaviour.
