CCMT 09T308 T9215 indexable turning insert — rhombic CCMT, 0.8 mm corner radius (Tungaloy)

CCMT09T308 T9215 is an ISO-standard indexable insert for external and internal turning, optimised for medium-steel machining and continuous to lightly interrupted cuts.

• CVD-coated carbide T9215 grade
• ISO rhombic CCMT 09 form
• 0.8 mm corner radius for versatile finishing
• Cylindrical hole with 40°–60° countersink

High productivity through wear-resistant grade and coating

The T9215 grade, a CVD-coated carbide, is specified for medium-steel applications where a balance of wear resistance and fracture toughness is required. This combination reduces flank and crater wear under steady cutting conditions and supports longer index intervals, which directly lowers tool-change frequency and increases machine uptime. The result is measurable productivity gains in batch production and serial turning, with fewer interruptions for insert replacement and consistent part-to-part quality.

Consistent seating and repeatability with ISO geometry

The rhombic CCMT form follows ISO-standard dimensions and ensures compatibility with common turning holders when the form, clearance angle, tolerance class, fastening method, size and thickness are matched. The insert features a 7° clearance angle and a 3.97 mm thickness, which together provide stable seating and predictable cutting behaviour. For workshops that value repeatable tolerances, using ISO-compliant indexable inserts makes tool inventory and holder selection straightforward and reduces set-up variability.

Controlled chip formation and reliable surface finish

A single-sided chipbreaker combined with a 0.8 mm corner radius delivers a balance between strength at the cutting edge and a refined surface finish on workpieces. The rhombic geometry supports both external profiling and internal boring operations where access is limited, while the cylindrical hole with a one-sided countersink (40°–60°) secures the insert in the pocket to maintain alignment under higher cutting forces. These features help achieve stable chip flow and minimise the risk of edge chipping during light interruptions.

Application guidance and practical selection advice

Designed for turning, the insert is best matched with chipbreaker and grade selection according to workpiece material, machining stability and cut type. For medium-steel operations with continuous cuts, the CVD-coated carbide grade is a first choice; for heavier interruptions or unstable setups, consider a more robust geometry or a reinforced clamping solution. For precise holder matching and cutting-parameter recommendations, technical specifications and compatibility information are available to support process planning and to safeguard cutting performance.

FAQ

What materials is this insert intended for?
The CCMT09T308 T9215 insert is specified primarily for medium-steel machining, where the CVD-coated carbide grade combines wear resistance with edge strength.

Is the insert compatible with standard CCMT holders?
Compatibility requires matching the insert form, 7° clearance angle, thickness and fastening style; the CCMT09T308 conforms to ISO dimensions for CCMT-type holders.

How does the 0.8 mm corner radius affect part finish?
A 0.8 mm corner radius provides a compromise between edge robustness and surface finish, improving edge strength while enabling good finishing on turned surfaces.

Can it be used for internal turning as well as external?
Yes, the rhombic shape and single-sided chipbreaker make the insert suitable for both external profiling and internal turning operations where access permits.

What fastening style does the insert require?
The insert features a cylindrical hole with a one-sided countersink (40°–60°) and needs a matching pocket and screw for secure clamping.
