CPMT 080204 T9215 indexable insert for turning by Tungaloy

A CPMT 080204 T9215 ISO-compliant indexable insert engineered for external and internal turning in medium-steel applications.

• CVD-coated carbide grade T9215
• Optimised for medium steel turning
• Rhombic insert, 80° approach angle
• One-sided chipbreaker, 0.4 mm radius

Consistent wear resistance through CVD coating for higher throughput

The CVD-coated carbide composition delivers a balance of wear resistance and fracture toughness, making the insert suitable for continuous and lightly interrupted turning. Chemical vapour deposition (CVD) produces a uniform hard layer that reduces abrasive wear during sustained cutting, which translates into longer edge life and fewer tool changes on the production line. For process planners this means predictable tool performance and improved machine uptime when working with medium-grade steels.

Geometry and chip control that stabilise the cut

The 80° rhombic geometry combined with an 11° clearance supports stable cutting forces and accurate tool positioning in both external and internal machining. The one-sided chipbreaker is optimised for medium steels to promote reliable chip formation and evacuation, reducing the likelihood of built-up edge and rework. A 0.4 mm corner radius gives a compromise between edge strength and achievable surface finish; smaller radii favour lighter finishes, while this radius enhances robustness where interrupted cuts occur.

Mounting compatibility and system composition for fast tool changeovers

Compatibility with a toolholder depends on form, clearance angle, tolerance class, fastening method, size and thickness. The product is supplied as an ISO-indexable plate designed to interface with the usual external holder or boring bar, plus the required shim/clamping set and replacement screws in a typical system. The insert’s cylindrical hole with single-sided countersink (40°–60°) ensures secure clamping and repeatable positioning, simplifying inventory management and reducing assembly time at the machine.

Practical guidance for application and process optimisation

The T9215 grade has been chosen as a first option for mid-range steel machining where a combination of productivity and reliable wear performance is required. Select the chipbreaker and cutting parameters according to component rigidity and machining stability; the insert performs best when paired with an appropriate holder and correct feed/speed for the chosen material. Regular monitoring of flank wear will provide clear criteria for tool change and support consistent component quality.

FAQ

What materials is this insert best suited for?
The Tungaloy CPMT 080204 T9215 insert is optimised for medium steel machining, combining wear resistance and fracture toughness for productive turning operations.

How does the chipbreaker affect performance?
The one-sided chipbreaker on this insert promotes stable chip formation and evacuation in medium-steel turning, helping to reduce built-up edge and improve surface quality.

What does the CPMT080204 designation mean for holders?
CPMT080204 identifies the insert geometry, size and hole arrangement; matching the insert to a holder requires checking form, clearance angle, tolerance class, fastening method, size and thickness to ensure compatible seating and clamping.

Is the insert suitable for interrupted cuts?
Yes. The T9215 grade and the 0.4 mm corner radius provide a balance of toughness and wear resistance that is appropriate for continuous and lightly interrupted cutting conditions.

What is the purpose of the countersunk hole?
The cylindrical hole with a single-sided countersink (40°–60°) ensures secure clamping and repeatable positioning when mounted in the appropriate ISO holder, simplifying reassembly after index changes.
