TNMG 220412 T9215 – TNMG turning insert by Tungaloy for medium steel turning, ISO triangular indexable insert

TNMG220412 T9215 is an ISO‑standard triangular turning insert designed for external and internal turning applications where productivity and tool life are priorities

• CVD‑coated carbide grade T9215
• ISO TNMG 220412 triangular insert
• Optimised for medium steel turning
• Double‑sided chipbreaker for longer life

Consistent cutting performance for medium steel

The insert is made from CVD‑coated carbide, grade T9215, formulated to balance wear resistance and toughness for the middle range of steel machining. This combination enables stable cutting at higher feed rates and supports a productive cycle on continuous to slightly interrupted cuts. Thanks to the 1.2 mm corner radius, the geometry reduces edge chipping on moderate interrupted cuts while maintaining acceptable surface finish. The result is a dependable tool body that translates into fewer tool changes and higher machine uptime.

Designed for straightforward integration into ISO tooling systems

Manufactured to the ISO TNMG 220412 form, the triangular insert is compatible with a wide range of standard external holders and boring bars when the holder’s form, clearance geometry, tolerance class, fastening method, size and thickness match the insert. The insert features a cylindrical mounting hole, a 0° clearance angle and a plate thickness of 4.76 mm, ensuring secure clamping and repeatable seating. The standardised form factor simplifies inventory and reduces the need for specialised holders, supporting a smoother workflow on mixed‑tooling shop floors.

Practical benefits and economic efficiency in daily turning

Equipped with a double‑sided chipbreaker, the insert offers two usable edges per indexation, enhancing value per insert and reducing tooling cost per component. The grade’s wear profile is well suited to maintain edge stability across longer tool lives, which contributes directly to predictable process windows and consistent surface quality. For workshops aiming to increase throughput without compromising reliability, this insert supports both higher material removal rates and controlled, repeatable outcomes in medium steel turning.

FAQ

What materials is this insert intended for?
This insert is optimised for medium steel applications; the T9215 CVD‑coated carbide grade performs best in steel turning where a balance of wear resistance and toughness is required.

How many cutting edges can be used per insert?
The triangular shape with a double‑sided chipbreaker provides multiple usable edges; indexation extends the productive life of each insert.

Is the insert compatible with standard TNMG holders?
Yes — compatibility depends on matching the TNMG form, clearance geometry, tolerance class, fastening and thickness; when these match, the insert seats and clamps securely.

What mounting hole type does the insert have?
The insert comes with a cylindrical mounting hole to suit common clamping systems and ensure repeatable seating.

Which SKU identifies this item for ordering?
Order using SKU 6773885‑Tungaloy or manufacturer article number 6773885 for clarity in procurement.
