CNMG120404 120404 T9215 turning indexable insert by Tungaloy — ISO rhombic insert for medium steel

A CNMG120404 T9215 insert engineered for turning operations on medium steels, offering ISO‑standard fit, a 0° clearance angle and a cylindrical central hole for secure mounting in compatible holders.

• CVD-coated carbide grade T9215
• Optimised for medium steel machining
• Rhombic CNMG 80° geometry with 0° clearance
• Cylindrical central hole, double-sided chipbreaker

Consistent productivity through optimised cutting grade and geometry

The combination of a CVD‑coated carbide substrate and the T9215 grade delivers a balance of wear resistance and fracture toughness suited to continuous and lightly interrupted turning. The rhombic 80° geometry provides a stable cutting edge that supports higher feed and depth parameters while maintaining dimensional accuracy. As an ISO‑standard insert, it allows straightforward replacement in standard CNMG holders, reducing setup time and enabling predictable cycle times in series production. The coating reduces flank and crater wear, extending effective tool life and lowering tooling costs per part.

Secure clamping and simple integration into existing tool systems

Designed with a cylindrical central hole and precise tolerances, the insert ensures reliable seating and repeatable positioning in compatible external holders and boring bars. The 0° clearance angle and the defined 0.4 mm corner radius aid in achieving consistent surface finish while the double‑sided chipbreaker offers two usable edges per index, improving economy and uptime. Compatibility depends on form, relief angle, tolerance class, attachment method, size and thickness; matching these parameters guarantees safe clamping and repeatable interchangeability across ISO‑compliant tool holders.

Low‑risk process implementation and clear material suitability

As a first choice for medium steel, this insert supports a wide range of operations from finishing to medium roughing when paired with appropriate feeds and speeds. The T9215 grade is intended to combine stable chip formation with reliable edge life, making it suitable for production environments seeking a compromise between throughput and tool longevity. The insert’s 4.76 mm thickness and rhombic shape also contribute to mechanical stability, reducing vibration susceptibility and helping to protect the cutting edge during shopfloor variability. Operators benefit from straightforward edge selection and fewer unexpected tool changes in long runs.

FAQ

Which materials is this insert best suited for?
The CNMG120404 T9215 insert is optimised for medium steel machining; the T9215 grade combines wear resistance and fracture toughness for continuous to lightly interrupted cuts.

Is the insert reversible and how many cutting edges are available?
Yes — the insert is double‑sided with a chipbreaker on both faces, providing two usable cutting edges per side and improving cost efficiency per index.

What determines compatibility with a tool holder?
Compatibility depends on matching the ISO form, relief angle, tolerance class, attachment method, size and thickness; the CNMG120404 geometry and cylindrical hole ensure proper seating in ISO‑compliant holders.

Can this insert be used for interrupted cuts?
The T9215 grade is suitable for continuous to lightly interrupted cuts; for heavy interruptions, assessment of cutting parameters and holder rigidity is recommended.

What are the key dimensions to check before ordering?
Verify the ISO code (120404), plate size (12 mm), thickness (4.76 mm), corner radius (0.4 mm) and hole style (cylindrical) to ensure interchangeability.
