TNMG220412 T9215 — Indexable turning insert by Tungaloy, CVD-coated for medium-steel turning

The TNMG220412 T9215 is an ISO-standard triangular indexable insert designed for external and internal turning, offering a balanced combination of wear resistance and toughness for productive machining.

• CVD-coated carbide grade T9215 for medium steel
• Triangular 60° insert with 1.2 mm corner radius
• Double-sided chipbreaker with cylindrical hole
• ISO-standard TNMG220412 for compatible holders

Consistent productivity for medium-steel turning

The combination of CVD-coated substrate and the T9215 grade provides a focused balance between wear resistance and fracture resistance, making the insert especially suitable for medium-steel machining. This material pairing supports stable cutting at elevated productivity levels in continuous to lightly interrupted cuts, reducing the frequency of tool changes and supporting predictable tool-life planning. The result is improved process economy through fewer stoppages and consistent part quality.

Compatibility and secure clamping to reduce setup time

Designed to the ISO indexable insert system, the triangular insert fits standard external holders and boring bars when matched for form, clearance angle, tolerance class, fastening method, size and thickness. The 60° geometry and the cylindrical locating hole simplify accurate seating and repeatable clamping, which lowers setup times and minimises chatter risk. Clear specification of those interface parameters enables quick tool replacement and easier inventory management across different tool families.

Reliable chip control and surface quality for turning tasks

A double-sided chipbreaker combined with a 1.2 mm corner radius delivers improved chip formation and evacuation in typical turning operations, which in turn supports consistent surface finish on turned components. The insert’s 0° relief angle and a plate thickness of 4.76 mm contribute to rigidity under cutting loads, helping to maintain dimensional stability in both external and internal turning. For workshops machining medium steels, this insert supports a good compromise between feed capability and finishing performance while offering versatile use across common turning tasks.

FAQ

What materials is this insert best suited for?
The TNMG220412 T9215 insert is optimised for medium steel machining; the CVD-coated carbide grade offers a balance of wear resistance and toughness for productive turning.

Is the insert reversible or single-use?
The triangular TNMG220412 is double-sided, allowing indexation to a fresh cutting edge when one edge becomes worn; this increases usable life per insert.

Which holders are compatible with this ISO insert?
Compatibility depends on matching the holder’s form, clearance angle, tolerance class, fastening method, size and thickness to the TNMG220412 specification; ISO-standard holders designed for TNMG inserts are suitable.

How does the chipbreaker affect machining performance?
The double-sided chipbreaker on this insert improves chip control and evacuation, promoting consistent surface finish and reducing the risk of chip-related interruptions during turning.

What is the manufacturer article number and SKU for ordering?
Manufacturer article number: TUN6774089; SKU listed as 6774089-Tungaloy for the TNMG220412 T9215 indexable insert.
