CNMG 090408 T9215 turning insert — CVD-coated carbide, 80° geometry, Tungaloy

The CNMG090408 T9215 Tungaloy turning insert is an ISO-standard rhombic indexable insert engineered for medium-steel turning, offering a robust balance of wear resistance and breakage safety in continuous to slightly interrupted cuts.

• CVD-coated cemented carbide T9215
• Suitable for medium steel turning
• Rhombic CNMG 80° geometry
• Double-sided chipbreaker, cylindrical hole

High productivity from a balanced grade and coating

The combination of T9215 and a CVD-coated cemented carbide substrate delivers a controlled wear pattern and good fracture resistance, which together support longer tool life and consistent part quality. This grade is specified for medium steel machining and is designed to remain stable under continuous and slightly interrupted cutting. For production environments seeking predictable lifetime and repeatable results, the choice of a robust, coated grade reduces unplanned tool changes and helps sustain throughput without compromising surface integrity.

Geometry that improves stability and surface finish

The CNMG rhombic geometry with an 80° included angle and a 0.8 mm nose radius provides a compromise between strength and finish: a larger effective cutting edge area for heavy engagement while still producing acceptable surface quality. The insert’s 0° relief angle, 4.76 mm thickness and double-sided chipbreaker contribute to secure clamping and repeatable orientation when indexed. A cylindrical hole ensures reliable fastening in compatible holders. Together, these geometry features translate into stable cutting behaviour and consistent component dimensional accuracy.

Simple system integration and predictable operation

As part of the ISO turning insert family, this component fits into established tool systems: appropriate external holders or boring bars, a support shim or clamping kit, plus replacement screws complete the assembly. The insert’s specification—size 09, ISO code 090408, and the choice of chipbreaker—allows selection that matches workpiece material, machining strategy and machine rigidity. Choosing the correct chipbreaker and holder pairing yields improved chip control and reduced vibration, which directly reduces cycle time and scrap rates in series production.

FAQ

What materials is this insert best suited to machine?
The CNMG090408 T9215 insert is optimised for medium steel applications; the T9215 grade combines wear resistance and fracture toughness for productive machining of steel workpieces.

Is the insert indexable and double-sided?
Yes — the CNMG geometry is indexable and the design includes a double-sided chipbreaker so each face can be reused, extending the effective service life of the insert (SKU 6772154-Tungaloy).

What does the T9215 designation indicate?
T9215 denotes a CVD-coated cemented carbide specification tuned for the middle range of steel machining, balancing abrasion resistance with mechanical strength for consistent performance.

Which geometry characteristics improve machining performance?
Key geometry features are the rhombic CNMG profile with an 80° included angle, 0.8 mm nose radius and 4.76 mm plate thickness; these deliver edge strength, stable engagement and good surface quality.

Can the insert be used for interrupted cuts?
The T9215 variant is intended for continuous to slightly interrupted cuts; for heavy interruptions a different grade or stronger geometry should be selected.

What determines holder compatibility for this insert?
Compatibility depends on holder form, relief angle, tolerance class, fastening method, size and plate thickness; matching these parameters ensures correct clamping and repeatable cutting performance.
