CNMG120408 T9225 – Tungaloy indexable insert for turning

The CNMG120408 T9225 is an ISO-standard, rhombic CNMG indexable insert designed for external and internal turning, offering a CVD-coated carbide grade optimised for medium-to-heavy steel machining.

• CVD-coated carbide grade T9225
• Universal grade for medium–heavy steel
• Rhombic CNMG shape with cylindrical hole
• 0.8 mm nose radius for stable cutting

Consistent production through high wear resistance and toughness

The T9225 grade is a CVD-coated carbide formulation engineered for a balance of hardness and toughness, making it suitable where variable engagement and occasional interrupted cuts occur. This combination reduces flank wear and extends edge life, which translates into fewer tool changes and higher machine uptime in continuous production. Choosing a grade with proven chip control capability supports predictable tool life, helping to plan maintenance intervals and lower overall machining costs while maintaining component quality.

Ease of integration with ISO turning systems

The rhombic CNMG form with an 80° cutting geometry and a cylindrical central hole ensures straightforward mounting in compatible external holders or boring bars. Critical compatibility is determined by insert form, clearance angle, tolerance class, fastening method, size and thickness; the insert here measures 12 mm across with a 4.76 mm plate thickness and a 0° clearance. These measurable values allow engineers to verify fitment quickly against holder specifications and avoid unexpected assembly issues on the shop floor.

Stable cutting and surface finish under demanding conditions

A 0.8 mm nose radius delivers a compromise between strength and finishing capability: it increases edge support for heavy cuts while still enabling acceptable surface roughness on typical turned parts. The double-sided chipbreaker design assists in fragmenting and evacuating chips during both continuous and interrupted cutting, reducing the risk of build-up and improving repeatable part quality. As an indexable insert, the component is reversible, offering two usable cutting edges and economical edge rotation during wear.

Practical benefits for workshop stock and process security

Standardised ISO geometry simplifies inventory management by allowing a single insert type to serve multiple machines and operations. The robust design and universal applicability of this grade make it a sensible choice for mixed-production environments where flexibility matters. Backed by a reputable manufacturer, the insert supports consistent machining results, which in turn fosters confidence among operators and planners that parts will meet dimensional and surface requirements batch after batch.

FAQ

What materials is this insert designed for?
The CNMG120408 T9225 insert by Tungaloy is optimised for medium-to-heavy steel machining; its CVD-coated carbide grade provides the toughness needed for variable engagement and light interruptions.

Can this CNMG insert be used in internal turning operations?
Yes; the rhombic CNMG form and cylindrical hole allow mounting in suitable boring bars for internal turning as well as external holders for general turning work.

How does the 0.8 mm nose radius affect cutting performance?
A 0.8 mm radius increases edge support, improving stability under heavier cuts and helping to maintain surface quality across typical turning passes.

Is the insert reversible and how does that impact tool costs?
The insert is double-sided and indexable, offering multiple usable edges; this reversibility reduces per-edge cost and simplifies in-process edge changes.

What should be checked for holder compatibility?
Verify holder form, tolerance class, fastening method, size and plate thickness against the insert’s CNMG 12 × 4.76 mm specification and 80° geometry to ensure correct fit and secure clamping.
