CPMT090304 T6215 CPMT indexable insert for Turning by Tungaloy — CVD-coated carbide, 0.4 mm radius, 80°

The CPMT090304 T6215 is an ISO rhombic insert designed for external and internal turning; it combines a wear-resistant CVD-coated carbide grade with a single-sided chipbreaker and an 80° approach geometry for consistent machining of stainless steels under stable to lightly interrupted conditions.

• CVD-coated carbide for wear resistance
• Compatible with ISO rhombic 09 holders
• 0.4 mm corner radius for reliable edge strength
• Single-sided chipbreaker with 80° geometry

Consistent tool life from the CVD-coated carbide grade

The insert is manufactured in a CVD-coated carbide grade (T6215) developed to resist abrasive wear and preserve cutting-edge integrity when machining stainless steels. The chemical vapour deposition layer provides a hard, adherent surface that reduces flank wear and helps to maintain dimensional stability across longer batches. As a result, process reliability improves and interruptions for tool changes are less frequent; this translates into more predictable machining cycles and fewer quality deviations.

Geometry and clamping designed for secure, repeatable performance

A precise 0.4 mm corner radius and the rhombic 09 form contribute to good edge strength and predictable cutting forces. The insert features an 80° approach geometry with a 3.18 mm plate thickness and an 11° clearance angle, providing mechanical robustness and secure seating in ISO-standard holders. The insert’s cylindrical hole with a one-sided countersink (40°–60°) ensures correct clamping alignment and repeatability; compatibility is determined by form, clearance angle, tolerance class, fastening, size and thickness, so matched holders and clamping kits are essential for full performance.

Process suitability and measurable production benefits

This grade and geometry combination is optimised for turning operations where stability is available—typical tasks include finishing and semi-finishing of corrosion-resistant alloys and similar materials. The single-sided chipbreaker assists in chip control under moderate depths of cut, reducing the risk of built-up edge and minimising rework. Specifying the correct chipbreaker and grade for the part material and machine rigidity supports higher productivity, reduces scrap rates and helps maintain surface quality without overcomplicating tool management.

Practical handling, selection advice and compatibility checks

The insert is supplied as an ISO-standard indexable plate and must be paired with a matching external holder, clamp set and replacement screws. For internal turning, select a stable boring bar with the corresponding ISO seat; for external operations, ensure that the holder geometry matches the rhombic 09 seating and 80° approach.

FAQ

Is this insert suitable for machining stainless steels? Yes. The CPMT090304 T6215 insert is specified for stainless steels, with a CVD-coated carbide grade and chipbreaker geometry optimised for stable to lightly interrupted turning operations.

Which holders are compatible with this insert? Compatibility requires holders that accept the rhombic 09 insert form with an 80° approach and matching seat dimensions; correct fit depends on form, clearance angle, tolerance class, fastening, size and thickness.

What does the grade designation T6215 indicate? T6215 denotes a CVD-coated carbide grade engineered for wear resistance and stable cutting when turning stainless steels; the coating improves flank and crater wear performance.

Can this insert be used for internal as well as external turning? Yes; the insert suits both external and internal turning tasks provided the holder or boring bar offers sufficient rigidity and the correct ISO seating and clamping are used.

How should the chipbreaker be chosen for specific parts? Select the chipbreaker based on workpiece material, depth of cut and machine stability; the single-sided chipbreaker on this insert supports effective chip control for many stainless-steel finishing and semi-finishing scenarios.
