CPMT 090308 T6215 – Turning insert, 80° rhombic, CVD-coated (Tungaloy)

The CPMT 090308 T6215 is an ISO rhombic indexable insert designed for external and internal turning, providing wear-resistant cutting performance for stainless steels under stable to lightly interrupted conditions.

• CVD-coated cemented carbide grade T6215
• 80° rhombic geometry for sturdy cutting
• Single-sided chipbreaker for controlled chips
• Cylindrical hole with 40°–60° countersink

Consistent tool life through advanced coating and grade selection

The combination of a CVD-coated cemented carbide substrate and the T6215 grade provides improved wear resistance and predictable performance in serial production. The CVD coating reduces flank wear and helps maintain dimensional stability over longer cutting times, which leads to fewer tool changes and reduced downtime. For operations where process stability is key, this material pairing supports higher productivity and repeatable component quality while simplifying grade selection for turning applications.

Secure clamping and robust geometry for heavy cuts

Featuring an 80° rhombic geometry, the insert offers a balanced edge angle that supports stable cutting forces and good resistance to edge chipping. The form, combined with the 0.8 mm corner radius, increases the contact area at entry, improving edge strength for interrupted cuts and medium-depth passes. This geometry is particularly advantageous when paired with a correctly matched insert holder and clamping set, since compatibility is determined by form, clearance angle, tolerance class, fastening method, size and thickness.

Improved chip control and surface finish for stainless steels

The insert’s single-sided chipbreaker is optimised for chip formation when machining corrosion-resistant alloys, helping to produce short, manageable chips and reducing the risk of surface damage. By selecting the right chipbreaker and machining parameters, the cutting edge maintains its profile longer and supports consistent surface integrity, which is essential when working with work-hardenable materials. The design supports finishing and semi-finishing passes where a predictable chip flow and stable cutting forces contribute directly to better part quality.

System compatibility and practical workshop benefits

As an ISO-standard turning plate, the insert integrates into a modular system consisting of a matching external holder or boring bar, a backing/clamp kit and replacement screws. The CPMT 090308 format with a cylindrical hole and one-sided countersink (40°–60°) simplifies secure fastening and repeatable positioning. Using widely recognised ISO designations makes tool inventory management easier and helps ensure replacement inserts fit known holders without adaptation.

Application guidance and technical support

For turning applications, select the chipbreaker and grade according to workpiece material, cutting depth and machine stability. The CVD-coated T6215 grade is particularly suited for turning stainless steels under stable conditions; for heavily interrupted cuts or extremely high temperatures, alternative grades or coolant strategies may be considered.

FAQ

What materials is this insert best suited for?
The CPMT 090308 T6215 insert is designed primarily for machining stainless steels; the CVD-coated cemented carbide and chipbreaker support wear resistance and controlled chips in such alloys.

How does the 80° geometry affect cutting performance?
An 80° rhombic geometry increases edge strength and supports stable cutting forces, which helps prevent chipping during interrupted cuts and provides reliable performance in turning operations.

Which holders are compatible with this ISO insert?
Compatibility is determined by the insert form, clearance angle, tolerance class, fastening method, size and thickness; the CPMT 090308 fits holders made for the CPMT ISO family when those parameters match.
