CNMG 120412 T9215 Tungaloy turning insert — ISO rhombic insert for medium-steel turning

CNMG 120412 T9215 Tungaloy turning insert designed for ISO-standard external and internal turning applications, offering wear resistance and edge stability for continuous to slightly interrupted cuts

• ISO rhombic insert CNMG 120412
• CVD-coated carbide T9215 grade
• 1.2 mm corner radius for robust edges
• Double-sided chipbreaker; suitable for turning

High productivity for medium-steel turning

The CVD-coated T9215 grade is developed as a first choice for medium-steel machining, combining high wear resistance with improved fracture toughness. The CVD-coated layer on the carbide substrate increases tool life under continuous operation and helps maintain consistent cutting parameters, which supports higher feed rates and longer uninterrupted production runs. This results in a more economical process through longer tool life and fewer indexings, translating into measurable savings on labour and tooling costs.

Durable edge stability and predictable surface finish

A 1.2 mm corner radius together with the double-sided chipbreaker provides a stable cutting edge that resists chipping and enables controlled chip formation. The rhombic geometry and an 80° approach angle deliver a reliable contact area between tool and workpiece, improving vibration resistance and promoting even flank wear. The 4.76 mm plate thickness adds stiffness to the cutting edge, which benefits surface integrity; for workshops seeking reproducible finish and dimensional stability, these design elements reduce rework and improve first-pass yield.

Straightforward compatibility and practical system use

The insert conforms to ISO dimensions for turning plates, so compatibility with holders is determined by form, relief angle, tolerance class, fastening method, size and thickness. The CNMG 120412 is supplied with a cylindrical centre hole for secure mounting and is double-sided for economical indexing. When integrating this component into an existing tool system, ensure the holder matches the CNMG profile and the 0° relief angle specification. For bespoke setups or uncertain matches, the Metav Werkzeuge team provides specification checks and advice to ensure the insert performs as intended in production environments.

FAQ

Which materials is this insert best suited for?
The Tungaloy CNMG 120412 T9215 insert is optimised for medium-steel machining; the T9215 grade balances wear resistance and fracture toughness for productive steel turning.

What is the corner radius and how does it affect performance?
The insert has a 1.2 mm corner radius, which improves edge strength and reduces the risk of chipping, contributing to a more stable cut and consistent surface finish when machining steel.

Is the insert reversible or single-use?
This is a double-sided insert with a central hole and chipbreaker on both sides, allowing indexing to a fresh edge and thus extending the usable life of each insert.

Can the insert be used for interrupted cuts?
The T9215 grade and robust geometry are suitable for continuous to slightly interrupted cuts; for heavy interruptions, a different grade or chipbreaker may be recommended.

How is compatibility with holders determined?
Compatibility depends on the insert form, relief angle, tolerance class, fastening method, size and thickness; ensure the toolholder accepts CNMG 120412 geometry and the 0° relief angle.
