CNMG120408 T9225 Tungaloy indexable turning insert — CVD‑coated carbide, 0.8 mm corner radius

CNMG120408 T9225 Tungaloy insert is a rhombic, ISO‑standard turning insert optimised for medium to heavy steel turning where interrupted cuts or variable engagement demand enhanced toughness and reliable edge life.

• ISO rhombic turning insert
• CVD‑coated carbide grade T9225
• 0.8 mm corner radius for robustness
• Cylindrical hole for secure clamping

Engineered for dependable steel turning

The CNMG120408 T9225 Tungaloy indexable insert is produced as an ISO‑standard component for conventional turning systems, combining a CVD‑coated carbide matrix with a universal T9225 grade. This grade is described as a robust, economical choice for medium to heavy Stahl machining, offering increased toughness where changing cutting conditions or light interruptions occur. Compatibility with a holder depends on form, clearance angle, tolerance class, size and thickness; these parameters ensure secure clamping and repeatable positioning when the correct seat and fastening hardware are used.

Precise geometry for stable, repeatable machining

The insert’s rhombic shape and 0.8 mm corner radius deliver a balance between edge strength and form accuracy, while the 4.76 mm thickness increases stability under downforce. The part features a cylindrical hole for positive fastening and a 0° clearance angle, enabling neutral engagement in a wide range of turning setups. A double‑sided chipbreaker is incorporated for indexable use, permitting two‑edge utilisation and therefore an improved cost per cutting edge. Choose the chipbreaker and insert variety to match the workpiece material and feed rates for predictable chip control and surface finish.

Practical advantages on the shop floor and process benefits

Adopting this insert brings measurable production benefits: the CVD coating enhances thermal and abrasive resistance, extending useful tool life in continuous and semi‑interrupted cuts; the universal character of the T9225 grade reduces the need for frequent grade changes across common Stahl components. The insert integrates into a system comprising an insert, matched external holder or boring bar, shim/clamp set and securing screw; keeping compatible spares on hand reduces machine downtime and simplifies set‑up. For operators and process planners, the result is steadier cycle times, consistent surface quality and reduced tooling complexity.

FAQ

What materials is this insert designed for?
The Tungaloy CNMG120408 T9225 insert is intended primarily for Stahl machining in medium to heavy turning applications; the CVD‑coated carbide composition gives improved wear resistance for such materials.

How does the corner radius influence performance?
A 0.8 mm corner radius increases edge strength and reduces edge chipping risk under heavier loads, which helps the insert maintain dimensional stability and consistent surface finish during turning.

Can the insert be used on both external and internal diameters?
Yes — the rhombic CNMG form and neutral 0° clearance make the insert compatible with appropriate external holders and boring bars for internal work, subject to correct holder geometry and clamping.

How many usable cutting edges are available per insert?
The double‑sided chipbreaker allows indexing of multiple edges; the exact number of cuts per insert depends on wear patterns, workpiece material and cutting parameters, but the design supports economical edge rotation.

What determines compatibility with a toolholder?
Compatibility is governed by insert form, clearance angle, tolerance class, fastening method, size and thickness; ensure the holder matches the ISO seat and clamp arrangement for correct seating and repeatability.
