SNMG120420 T9215 Tungaloy indexable insert — CVD-coated carbide for productive medium-steel turning

The SNMG120420 T9215 Tungaloy insert is a square ISO-form turning insert engineered for external and internal turning of medium-strength steels, offering a balance of wear resistance and fracture toughness for continuous to lightly interrupted cuts.

• CVD-coated carbide grade T9215 for medium steel
• Double-sided chipbreaker for flexible use
• Square SNMG form, 12 mm size, 4.76 mm thick
• Cylindrical hole for secure mounting

Consistent productivity for medium-steel applications

The combination of a CVD-coated surface and a robust carbide substrate makes this insert particularly suited to stable, productive turning operations. As a first-choice grade for mid-range steels, T9215 delivers enhanced wear resistance without compromising fracture toughness, which helps to reduce unscheduled tool changes and maintain cycle times. The geometry aims to support both external and internal facing and turning, while the double-sided nature extends usable life per index, contributing to lower tooling costs per part and a smoother manufacturing cadence.

Secure mounting and simple indexability for reliable setups

Built in the square SNMG format with a nominal 12 mm size and a plate thickness of 4.76 mm, the indexable plate features a cylindrical hole and a standard fastening arrangement that ensures repeatable clamping in compatible holders. The 2 mm corner radius and the double-sided chipbreaker allow two usable edges per side, and the specified relief angle of 0° governs clearance and contact with the workpiece. Compatibility to a particular holder depends on form, relief angle, tolerance class, fastening method, size and thickness, and the complete system typically comprises the insert, matching external holder or boring bar, shim/underplate and clamping screws.

CVD protection for longer tool life and process stability

The chemical vapour deposition treatment on the T9215 grade provides thermal and tribological advantages: improved resistance to abrasive wear and elevated temperatures that occur in high-throughput turning. This leads to steadier tool life and more consistent surface finishes when parameters and workpiece stability are appropriate. Selection of the correct chipbreaker, insert grade and holder rigidity remains critical — grades such as T9215 are designed for continuous to lightly interrupted cuts, so match cutting data and clamping stiffness to avoid premature edge failure. For advice on holder compatibility or grade selection, Metav Werkzeuge consultants can provide application-specific recommendations and machining guidelines.

FAQ

Which materials is this insert intended for?
The SNMG120420 T9215 Tungaloy insert is primarily intended for medium steels; the T9215 grade and CVD-coated carbide substrate deliver wear resistance and toughness suited to typical steel turning tasks.

What chipbreaker and edge configuration does it have?
This indexable plate features a double-sided chipbreaker and a 2 mm corner radius, providing flexible edge options and two usable cutting edges per side for extended service life.

What are the key dimensions and how is it mounted?
The insert is a square SNMG form, 12 mm in size with a 4.76 mm thickness and a cylindrical hole for secure mounting; the manufacturer article number is 6773919 for reference.

Can this insert handle interrupted cuts?
The T9215 grade is suitable for continuous to light interrupted cuts; for heavier interruptions, evaluate holder rigidity and consider alternative grades or geometries designed for interrupted machining.

How to ensure compatibility with holders and clamping systems?
Compatibility is determined by insert form, relief angle, tolerance class, fastening method, size and thickness; for application-specific matching, refer to Metav Werkzeuge or consult holder documentation when using the SNMG120420 T9215 Tungaloy insert (SKU 6773919-Tungaloy).
