CCMT 120408 T9215 turning insert – ISO indexable insert by Tungaloy

CCMT120408 T9215 is an ISO-standard indexable insert designed for productive external and internal turning of medium steel materials.

• CVD-coated carbide grade T9215
• 0.8 mm corner radius for edge strength
• 80° rhombic form with 7° relief angle
• Cylindrical hole with 40°–60° countersink

Consistent wear resistance for medium-steel turning

The insert is manufactured in CVD-coated carbide, grade T9215, which delivers a balance of wear resistance and fracture toughness. This combination makes the tool particularly suitable for medium steel machining under continuous to slightly interrupted cutting conditions, improving run time between indexings. The coating reduces adhesion and flank wear while the carbide substrate maintains cutting-edge stability, so production runs can sustain higher productivity with fewer unplanned interruptions.

Geometry that simplifies holder compatibility and clamping

Defined by ISO form and dimensions, the rhombic 80° geometry and 7° relief angle ensure predictable seating in compatible toolholders. Compatibility is established by form, relief angle, tolerance class, fastening method, size and thickness; the insert’s rhombic shape and 4.76 mm thickness allow integration into common external holders and boring bars. The cylindrical hole with a single-sided countersink supports secure clamping and straightforward replacement, reducing setup time and risk of misalignment.

Edge protection and chip control for production environments

The 0.8 mm corner radius increases edge strength and reduces chipping during slightly interrupted cuts, while the one-sided chipbreaker assists consistent chip formation and evacuation on turning operations. These features together enhance surface finish and process reliability, translating to lower rework rates and more predictable tool life. In practice, the indexable insert forms part of a system comprising a matching holder, shim and clamping set plus replacement screws for efficient maintenance cycles.

Practical benefits for workshop use and process planning

As an ISO-standard insert, this product supports inventory rationalisation and easy replacement across multiple machines. The CVD coating and carbide construction afford longer service life in demanding batches, helping to lower total machining costs through fewer tool changes. For operations seeking reproducible results, the insert’s geometry and grade make it straightforward to specify cutting data and tolerances, while the standardised format aids cross-platform planning and tool management.

FAQ

What materials is this insert suited for?
The CCMT120408 T9215 indexable insert is optimised for medium steel machining; the T9215 grade provides a blend of wear resistance and toughness suitable for continuous to slightly interrupted turning operations.

How does the chipbreaker affect performance?
The one-sided chipbreaker on this insert promotes controlled chip formation and evacuation during turning, improving surface finish and reducing the likelihood of recutting long chips in production cycles.

Which holder features are required for compatibility?
Compatibility depends on holder form, relief angle, tolerance class, fastening method, size and thickness; ensure the toolholder accepts an ISO CCMT 120408 rhombic insert with the specified 7° relief and 4.76 mm thickness.

Is the insert good for interrupted cuts?
Yes—the carbide substrate combined with the 0.8 mm corner radius and CVD coating enhances fracture resistance and wear performance in continuous to slightly interrupted cutting situations.

What is the manufacturer SKU and article number for ordering?
The manufacturer SKU is TUN6772436 and the article number is 6772436 for the Tungaloy CCMT120408 T9215 turning insert.
