CNMG 120402 T9225 — Indexable insert for turning by Tungaloy

The CNMG120402 T9225 is an ISO rhombic indexable insert designed for external and internal turning, optimised for medium-to-heavy steel machining and intermittent cuts.

• ISO rhombic 80° geometry for turning
• CVD-coated cemented carbide T9225
• Double-sided chipbreaker with cylindrical hole
• 12 mm size, 4.76 mm thickness, 0.2 mm radius

Consistent cutting performance where conditions vary

The combination of a CVD-coated surface and cemented carbide substrate in the T9225 grade delivers a balance of toughness and wear resistance that is particularly suitable for medium-to-heavy steel machining. This composition supports reliable edge life under slightly interrupted cuts and fluctuating engagement, reducing unscheduled tool changes. The coating enhances thermal stability and abrasion resistance, so the tool keeps performance consistent across varied feeds and speeds while maintaining acceptable surface quality.

Clear compatibility and secure clamping for predictable results

As an ISO turning insert, the rhombic 80° geometry and the specified dimensions ensure compatibility with standard ISO holders when matching form, relief angle, tolerance class, fastening method, size and thickness. The insert is supplied double-sided, with a cylindrical hole for positive locating and repeatable seating; this allows economical use of both cutting edges and straightforward indexing. Noting the 0° clearance angle and the physical measures helps to identify the correct holder and clamping kit to achieve secure fixation and consistent tool projection.

Designed to improve uptime and operational economy

Selecting a robust universal grade such as T9225 supports stable chip formation and extended service intervals, which contributes directly to shop-floor productivity. The double-sided chipbreaker reduces chip control issues in a wide range of steels and cutting conditions, decreasing machine downtime and handling effort. Fewer insert changes and predictable wear behaviour translate into lower per-part tooling costs and a more efficient machining cycle, a tangible advantage for batch production and mixed-lot environments.

Practical guidance for turning applications on the shop floor

For external and internal turning applications, choose the chipbreaker and the insert grade according to workpiece material and rigidity of the setup. The 0.2 mm corner radius provides a good compromise between strength and edge definition for finishing and semi-finishing passes; the 12 mm size and 4.76 mm thickness are typical for robust external operations and allow for sufficient clamping surface. When mounting, verify holder compatibility with the ISO designation and confirm the double-sided chipbreaker orientation for optimum chip flow and evacuation.

FAQ

Which turning operations is this insert intended for?
The CNMG120402 T9225 indexable insert by Tungaloy is intended for external and internal turning operations, especially where medium-to-heavy steel machining and slightly interrupted cuts demand a tough, wear-resistant grade.

How is holder compatibility ensured?
Compatibility depends on matching the ISO geometry, the relief/freiwinkel, the tolerance class, the fixing method and the insert size/thickness; the CNMG120402 form and 80° rhombic geometry assist in selecting the correct ISO holder.

What do the core specifications mean for machining?
The CVD-coated cemented carbide and T9225 grade signal a balance of wear resistance and toughness suited to steels, while the 0.2 mm corner radius indicates suitability for mixed finishing and semi-finishing passes.

Is the insert reversible or single-use per edge?
This insert is double-sided with a cylindrical hole, allowing indexing of both cutting edges and improving economical use of the insert in production.

Which SKU should be referenced when ordering or enquiring?
Reference SKU 6966059-Tungaloy or Manufacturer SKU TUN6966059 when discussing the CNMG120402 T9225 Tungaloy indexable insert to ensure precise identification.
