SNMG 120404 T9215 indexable turning insert by Tungaloy — 0.4 mm radius, ISO SNMG 120404

The SNMG120404 T9215 is an ISO‑standard indexable insert designed for external and internal turning of medium steels, offering a balance of wear resistance and fracture toughness for high productivity.

• CVD-coated carbide grade T9215
• 0.4 mm corner radius for versatility
• Double-sided chipbreaker for stability
• ISO SNMG 120404 format with cylindrical hole

Reliable wear resistance for productive turning

The CVD‑coated carbide substrate of this grade delivers high wear resistance while retaining sufficient toughness for routine shop use. The T9215 composition is tailored for medium steel machining and is rated for continuous to slightly interrupted cuts, which supports longer cutting intervals and a predictable tool life. These characteristics translate directly into fewer insert changes and improved process efficiency on series production runs.

Consistent chip control to reduce interruptions

A double-sided chipbreaker is incorporated to give controlled chip formation across a range of cutting conditions, improving surface quality and reducing the risk of chip‑related downtime. Effective chip control reduces the need for manual intervention at the machine, contributes to safer operation and helps maintain consistent cycle times, particularly when machining parts that demand repeatable surface finish and dimension stability.

Precise fit and secure clamping for dimensional stability

The insert is supplied in the ISO SNMG 120404 format with a cylindrical hole, enabling secure fastening in compatible holders. Compatibility with a given holder is determined by insert shape, relief angle, tolerance class, fastening method, size and thickness — all factors that ensure a stable cutting edge position and repeatable results. The 0° relief angle and square form contribute to predictable cutting geometry and ease of indexing.

Practical selection for everyday workshop productivity

With a 0.4 mm corner radius and a plate thickness of 4.76 mm, this insert suits a wide range of turning tasks where a balance between edge strength and detail is required. The system approach — an ISO insert plus a matching external holder or boring bar, a shim/clamp set and spare screws — simplifies inventory and replacement. For routine turning of shafts, faces and shoulder operations in medium‑strength steels, this insert offers a pragmatic combination of performance and robustness.

FAQ

Which materials is this insert best suited for?
The Tungaloy SNMG120404 T9215 insert is optimised for medium steel applications; the T9215 grade combines wear resistance with fracture toughness for continuous to slightly interrupted cuts.

Is the SNMG120404 compatible with standard SNMG holders?
Compatibility depends on holder form, relief angle and tolerance class; the SNMG120404 format and cylindrical hole are standard for many SNMG holders, but matching by holder specification is recommended.

What cutting conditions are appropriate for this grade?
The T9215 grade is intended for productive turning at moderate to high cutting speeds in medium steels, favouring continuous to slightly interrupted cuts where both wear resistance and toughness are needed.

How does the 0.4 mm corner radius affect performance?
A 0.4 mm radius offers a compromise between edge strength and the ability to produce defined contours; it improves robustness over finer radii while still permitting reasonable surface finish quality.

Can the insert handle light interruptions or unstable setups?
Yes — the T9215 grade’s balanced toughness provides resistance to breakage under light interruptions, and the double-sided chipbreaker helps maintain stable cutting behaviour in marginally interrupted cuts.
