CPMT090304 T6215 Tungaloy indexable insert for turning (ISO CPMT090304, CVD-coated carbide)

CPMT090304 T6215 is an ISO rhombic indexable insert designed for robust external and internal turning of stainless steels under stable to lightly interrupted conditions

• CVD-coated carbide grade T6215
• ISO CPMT090304 rhombic 80° insert
• Suitable for stainless steel turning
• Cylindrical hole with 40°–60° countersink

Proven wear resistance for consistent production

The CVD-coated carbide composition of the insert delivers wear resistance and predictable tool life under continuous and lightly interrupted cuts. The T6215 grade is engineered to maintain edge integrity when machining stainless steels, which tend to work-harden; this reduces tool changes and supports longer uninterrupted production runs. The chemical vapour deposition layer improves thermal stability at the cutting zone, so surface finish and dimensional repeatability remain consistent even when feeds and speeds vary slightly.

Precise fit and clamping for secure cutting

Compatibility with ISO toolholders depends on the insert’s shape, relief angle, tolerance class, fastening and thickness; the CPMT090304 geometry ensures secure locating in standard CPMT pockets. The insert features an 80° rhombic form, 11° relief angle, a 0.4 mm nose radius and a cylindrical hole with single-sided countersink (40°–60°), enabling reliable clamping and repeatable positioning. Correct selection of the matching holder, backing shim and screw eliminates movement during cutting, which in turn reduces vibration and improves tool life and part quality.

Productivity gains through application-focused design

The single-sided chipbreaker and the combination of coating and substrate are optimised for chip control when turning stainless steels; this fosters stable chip formation and reduces the risk of built-up edge. By choosing the appropriate grade and chipbreaker for the workpiece and machining stability, cycle times can be shortened and insert usage maximised. The ISO standard format also simplifies inventory management and allows quick replacement without special adapters, supporting efficient setup changes on high-mix production lines.

FAQ

What materials is the insert suitable for?
The Tungaloy CPMT090304 T6215 insert is specified for machining stainless steels; the T6215 CVD-coated carbide provides the wear resistance needed for these alloys.

Which holders are compatible with this ISO insert?
Compatibility is determined by form, clearance angle, tolerance class, fastening, size and thickness; the CPMT090304 geometry fits standard CPMT pockets designed for 09-size rhombic inserts.

How does the chipbreaker affect performance?
The single-sided chipbreaker on this insert promotes controlled chip formation for turning stainless steels, helping to avoid long, stringy chips and improving surface finish.

What are the key dimensions to check before fitting the insert?
Verify the insert designation (CPMT090304), thickness 3.18 mm, corner radius 0.4 mm and the hole/counterbore details to ensure a secure and repeatable clamp in the chosen holder.
