CNMG 120408 T9215 — Indexable turning insert, CVD‑coated carbide by Tungaloy

A CNMG 120408 T9215 indexable turning insert engineered for medium steel machining within ISO tool systems

• CVD-coated carbide T9215
• Optimised for medium steel turning
• Double-sided chipbreaker for economy
• 0.8 mm corner radius for stable edge

Boost productivity with a wear‑resistant grade

The combination of CVD-coated carbide and the T9215 designation makes this insert a dependable choice for demanding production environments where tool life and process stability matter. The grade balances wear resistance with fracture toughness to maintain a predictable tool life under continuous and lightly interrupted cutting conditions, which translates into higher productivity and fewer tool changes. This reliability helps to reduce machine downtime and contributes to a smoother production flow when machining medium steels.

Secure fit and simple integration into ISO tool systems

Designed in the familiar ISO CNMG form, the insert's rhomboid geometry and cylindrical hole ensure compatibility with a wide range of standard external holders. The designation CNMG120408 communicates the geometry and size, while the 4.76 mm thickness and precise tolerances determine the clamping and engagement in the toolholder. Compatibility relies on matching form, relief angle, tolerance class, fastening method, size and thickness; selecting a holder with the correct seat and screw guarantees repeatable positioning and consistent cutting behaviour.

Predictable surface finish and stable edge life through geometry

The 0.8 mm corner radius strengthens the cutting edge and moderates chip formation, helping to produce consistent surface quality without excessive cutting forces. The double-sided chipbreaker allows two usable edges per index, improving cost efficiency and reducing inventory consumption. Geometry features such as the neutral relief and robust core make the insert suitable for both external and some internal turning tasks, especially for continuous to light interrupted cuts, where a stable cutting edge and controlled chip flow are essential for reproducible results.

Practical guidance for selection and application

For economical machining, pair this insert with an appropriately rated external holder, matching screw and, if required, a backing plate or clamping set to ensure correct seating. The rhomboid shape and the with cylindrical hole configuration permit straightforward indexing and secure fastening; the CVD coating improves resistance against built-up edge and abrasion in steel turning. When selecting cutting parameters, favour the grade's strength by maintaining steady feeds and speeds appropriate to medium steel to exploit the insert's combination of edge stability and wear performance.

FAQ

Which materials suit this insert best?
The CNMG 120408 T9215 insert is specified for medium steel machining and performs well in continuous to light interrupted cuts thanks to the Tungaloy T9215 grade and its CVD-coated carbide substrate.

How is the insert secured in the holder?
This ISO CNMG insert uses a cylindrical hole and standard clamping screw; correct seating depends on matching the holder form, relief angle and thickness to the insert specification.

What advantages does the T9215 grade provide?
T9215 offers a balance of wear resistance and fracture toughness that supports stable machining and longer edge life for productive turning of medium steels with the CNMG geometry.

Can both sides of the insert be used?
Yes, the insert features a double-sided chipbreaker, allowing indexing to a fresh cutting edge and improving the economic use of each insert.

Which holders are compatible with CNMG120408?
Compatibility requires ISO CNMG-compatible external holders sized for 12 mm inserts with 4.76 mm thickness and the appropriate clamping geometry; check holder specifications against the insert's form and tolerance class.
