TNMG 220408 T9215 — Turning indexable insert by Tungaloy, CVD-coated carbide, 60°

The TNMG220408 T9215 is an ISO-standard triangular turning insert intended for external and internal turning; the geometry and grade make it suited to medium steel machining.

• CVD-coated carbide for high wear resistance
• Optimised toughness for stable cutting
• ISO TNMG 220408 form with 60° geometry
• Double-sided chipbreaker for versatile use

Engineered for consistent, productive turning

The ISO-standard form guarantees interchangeability with matching holders when the insert's form, relief angle, tolerance class, fastening method, size and thickness align. That standardisation reduces setup complexity and shortens changeover times, translating into more uptime on the shopfloor. As an indexable cutting component, the insert allows rapid re-indexing to a fresh edge, supporting a steady production flow and straightforward tooling management.

Grade and coating tailored for medium steel productivity

The T9215 composition is a CVD-coated carbide grade designed as a first choice for medium steel. The chemical vapour deposition layer improves surface hardness and wear resistance, while the carbide substrate provides the core strength for fracture toughness. Together these traits sustain cutting performance during continuous and light interrupted cuts, helping to extend edge life and maintain consistent part quality under productive cutting conditions.

Geometry and chip control for reliable surface finish

The triangular 60° geometry combined with a 0.8 mm corner radius balances strength and finish: the sharper radius supports finer surface quality while the robust form resists edge breakage. The insert features a double-sided chipbreaker that helps control chip formation across a range of feeds, and a cylindrical hole for secure clamping. Plate thickness of 4.76 mm and the 22 mm size contribute to mechanical stability during heavier cuts, reducing vibration and improving repeatability.

Practical selection and safe operating approach

Select the chipbreaker and grade in line with material, stability of the setup and the type of cut; for medium steel the T9215 grade is optimised for high productivity with reliable edge life. Ensure the toolholder matches the insert form and tolerance class to avoid seating errors. Start with conservative cutting data when introducing a new insert into a process and then advance parameters while monitoring tool wear.

FAQ

Is this insert suitable for steel machining?
Yes. The T9215 CVD-coated grade on the TNMG220408 insert is specified as a first choice for medium steel and combines wear resistance with toughness for productive turning.

What are the key geometry values of the insert?
The TNMG220408 insert has a 60° included angle, a corner radius of 0.8 mm, and a plate thickness of 4.76 mm; it also features a cylindrical hole for clamping.

Which operations are appropriate for this insert?
The insert is designed for both external and internal turning and performs well in continuous and lightly interrupted cuts when used with the correct chipbreaker and stable setup.

How does the CVD coating affect performance?
CVD-coated surfaces increase hardness and resistance to abrasive wear while the carbide substrate preserves edge strength, resulting in longer edge life under productive cutting conditions.

How is holder compatibility determined?
Compatibility depends on the insert's form, relief angle, tolerance class, fastening method, size and thickness; matching these parameters ensures correct seating and secure clamping.
