CPMT 09T302 T6215 — Tungaloy indexable turning insert for turning, CVD-coated carbide, 0.2 mm

The CPMT09T302 T6215 is an ISO-form indexable insert designed for external and internal turning; its geometry and grade suit stainless-steel machining under stable to slightly interrupted conditions.

• CVD-coated carbide for high wear resistance
• Optimised for stainless-steel turning
• Rhombic 80° shape, 11° relief angle
• Single-sided chipbreaker for reliable chips
• Cylindrical hole with countersink 40°–60°

Consistent machining performance through a wear-resistant grade

The combination of a CVD-coated carbide substrate and the T6215 grade delivers improved resistance to abrasive and adhesive wear when machining stainless steels. This means longer intervals between index changes and a predictable edge life, which supports stable cycle times and reduced process interruptions. The coated substrate reduces flank wear and helps maintain surface finish quality over longer tool life, translating into lower overall operating costs for medium to high-volume turning.

Geometric design that enhances dimensional accuracy

The rhombic plate with an 80° included angle and an 11° relief provides a balance between strength and accessibility for diverse turning tasks. The small 0.2 mm nose radius helps achieve fine detail and tight tolerances while the plate thickness of 3.97 mm ensures sufficient support in the holder for stable cutting. Together, these geometric features improve repeatability and help maintain consistent workpiece dimensions even under moderate interruptions.

Practical compatibility and handling for workshop use

The insert follows the ISO designation and is compatible with holders according to form, clearance angle, tolerance class, fastening method, size and thickness. The single-sided chipbreaker is matched to the grade to promote controlled chip formation during turning, easing chip evacuation and reducing heat concentration. The cylindrical hole with a single-sided countersink (40°–60°) ensures secure clamping and easy replacement. For best results, choose the chipbreaker and grade according to the workpiece material and the rigidity of the set-up.

FAQ

What materials is this insert recommended for?
The CPMT09T302 T6215 insert is recommended primarily for stainless steels, where its CVD-coated carbide grade T6215 provides wear resistance and good surface finish under stable cutting conditions.

Which toolholders are compatible with this ISO insert?
Compatibility depends on holder form, clearance angle, tolerance class, fastening and size; the CPMT09T302 follows ISO conventions and fits holders made for CPMT-style rhombic inserts.

How does the chipbreaker affect machining?
The single-sided chipbreaker on this insert promotes controlled chip formation and evacuation during turning, reducing the risk of built-up edge and improving process stability with the T6215 grade.

Is the insert suitable for interrupted cuts?
The insert is designed for stable to slightly interrupted conditions; heavy interruptions may require a different geometry or a tougher grade.

How should the nose radius be chosen for precision tasks?
The 0.2 mm nose radius offers fine detail and tighter tolerance control; for heavier stock removal a larger radius would be preferable, but that changes the cutting forces and may affect finish.
