CCMT 120408 T9215 Wendeplatten - Tungaloy

Take advantage of the combination of CVD-coated carbide (T9215) for enhanced wear resistance and a CCMT120408 rhombic geometry with 0.8 mm nose radius for stable cutting performance in medium-steel turning; order directly via Metav Werkzeuge or request technical advice if required.

CCMT120408 T9215 turning insert – Tungaloy

The CCMT120408 T9215 is an ISO-format turning indexable insert engineered for external and internal turning of medium steels, offering a balance of wear resistance and fracture toughness.

• CVD-coated carbide (T9215) for high wear resistance
• ISO CCMT120408 rhombic insert with 0.8 mm nose radius
• Designed for medium-steel turning and reliable productivity

Product grade that raises throughput in medium-steel turning

The CVD-coated carbide grade T9215 delivers a hard, wear-resistant surface while maintaining core toughness, making it well suited for continuous to light interrupted cuts in medium-steel applications. As a CVD-coated substrate, the grade reduces flank and crater wear under typical turning feeds and speeds, which translates into longer tool life and less frequent index changes. For production-focused workshops, this means fewer tool interventions and more consistent cycle times—quality and economy combined.

Geometry and clamping that enhances stability and repeatability

The ISO CCMT120408 geometry denotes a standard rhombic shape with an included angle that supports a wide range of toolholder pockets. The insert’s 0.8 mm nose radius gives a predictable cutting edge for improved surface finish without overloading the tool, while the 7° clearance angle assists chip evacuation and reduces rubbing. The insert features a cylindrical hole with a one-sided countersink (40°–60°) for secure clamping in compatible holders. Compatibility to a holder is determined by form, clearance angle, tolerance class, fastening method, size and thickness, so matching pocket design and clamping hardware is essential for optimal performance.

Practical selection and machining advantages

A single-sided chipbreaker in this indexable insert guides chips for controlled evacuation and reduced tool pressure peaks, which supports steady cutting and consistent surface quality. When paired with a correctly matched holder and clamping set, the grade and chip geometry minimise vibration and risk of edge chipping, particularly under slightly interrupted cuts. For operations seeking reproducible results, choosing this insert helps secure stable material removal rates and predictable tool-change intervals—advantages that improve overall process reliability and part quality.

FAQ

What materials is this insert suitable for?
The CCMT120408 T9215 insert from Tungaloy is optimised for medium-steel machining and combines wear resistance with toughness for continuous to light interrupted cuts.

Which toolholders fit the CCMT120408 geometry?
Holders designed for ISO CCMT inserts with matching form, clearance angle, tolerance class, fastening method, size and thickness will accept this insert; check the holder pocket and clamping method before mounting.

How does the T9215 coating affect tool life?
The CVD-coated T9215 grade enhances wear resistance and reduces flank and crater wear on the carbide substrate, resulting in longer tool life under appropriate cutting parameters.

Can this insert be used for finishing passes?
Yes—thanks to the 0.8 mm nose radius and rhombic geometry, the insert provides a consistent surface finish when cutting conditions and holder rigidity are suitable.

What role does the chipbreaker play for this insert?
The single-sided chipbreaker controls chip formation and evacuation, lowering cutting forces and helping to maintain stability and predictable tool performance.
