CCMT09T308 T9215 – CCMT indexable turning insert, CVD-coated carbide, 0.8 mm radius (Tungaloy)

A CCMT09T308 T9215 indexable turning insert for external and internal turning, optimised for medium steel machining and compatible with ISO toolholders.

• CVD-coated carbide for high wear resistance
• Optimised for medium steel machining
• Rhombic CCMT shape with 0.8 mm radius
• Cylindrical hole with 40°–60° countersink

Delivering consistent productivity through wear-resistant coating

The combination of a CVD coating on a carbide substrate provides a balance of wear resistance and fracture toughness that supports sustained cutting performance in continuous and lightly interrupted cuts. This translates into longer tool life and fewer index changes, which reduces downtime and contributes to more predictable production schedules. The coating chemistry is selected to maintain edge integrity at elevated temperatures typical of medium steel turning, helping to preserve surface finish and dimensional stability.

Straightforward compatibility and secure clamping for reliable operation

Built to the ISO CCMT format, the insert is designed for compatibility with standard ISO external holders and boring bars. The rhombic geometry combined with a cylindrical hole and a one-sided countersink (40°–60°) ensures secure clamping and repeatable seating, reducing the risk of movement under load. Clearances such as the 7° relief angle and the specified tolerance classes determine fit; matching holders by form, thickness and fastening method guarantees a safe, stable assembly and consistent cutting behaviour.

Practical explanation of geometry and cutting behaviour

A 0.8 mm corner radius provides a compromise between edge robustness and the ability to maintain smaller radii for fine profiles. The rhombic CCMT form gives versatile approach angles for both external turning and light boring operations, while the one-sided chipbreaker supports controlled chip formation when machining medium steel. For users with limited metallurgical background: chipbreakers mechanically shape the chip to prevent long, entangling swarf and to optimise heat evacuation from the cutting edge, improving safety and surface quality.

Application guidance to maximise process efficiency

Select the T9215 grade when machining general medium steels where a balance of wear resistance and toughness is required; the grade is suited to continuous to slightly interrupted cuts. Combining this insert with appropriate speeds, feeds and coolant strategies yields improved tool life and surface integrity. For process planners, the predictable wear pattern of this CVD-coated grade simplifies tool-change intervals and inventory planning, supporting higher throughput and lower unit costs in series production.

FAQ

What materials is this insert best suited for?
The Tungaloy CCMT09T308 T9215 insert is optimised for medium steel machining; the CVD-coated carbide grade offers a good balance of wear resistance and toughness for continuous to lightly interrupted cuts.

How is the insert clamped in a holder?
Clamping requires a matching ISO CCMT holder that accommodates the rhombic form, plate thickness (3.97 mm) and the cylindrical hole with countersink; the specified countersink angle (40°–60°) supports secure, repeatable seating.

What does the T9215 designation mean for performance?
T9215 is a CVD-coated carbide grade selected to combine high wear resistance with good fracture tolerance, making it a first choice for productive machining of medium steels while maintaining edge stability.

Can this insert be used for interrupted cuts?
Yes; the grade and geometry handle continuous to slightly interrupted cuts. For heavily interrupted operations, a different geometry or a more shock-resistant grade should be considered.

Which holders are compatible with this insert?
Any ISO-compatible CCMT external holder or boring bar that matches the plate form, size 09, thickness 3.97 mm and relief angle will be compatible; correct matching of tolerance class and clamping method is essential.
