CPMT 09T304 AH8015 indexable insert for turning — PVD-coated carbide, Tungaloy

CPMT 09T304 AH8015 is an ISO-standard rhombic indexable insert intended for external and internal turning of heat-resistant alloys and general turning applications.

• ISO rhombic insert CPMT 09T304
• PVD-coated AH8015 carbide grade
• 0.4 mm corner radius for precision
• Single-sided chipbreaker for reliable chips

Higher productivity on heat-resistant alloys

The AH8015 grade combines a PVD coating with a wear-resistant carbide substrate to deliver an effective balance between edge stability and abrasion resistance when machining heat-resistant alloys. This results in longer tool life under intermittent heat exposure and fewer insert changes, which raises productive uptime. The controlled coating structure also improves consistency across batches, so process parameters remain stable over longer series runs.

Predictable fit and straightforward integration

ISO standardisation ensures the insert’s form, clearance and tolerance classes align with common holders and boring bars, making fixture selection and setup straightforward. The rhombic shape with an 80° approach angle and defined 11° clearance reduces the need for extensive trial cuts. As compatibility depends on form, relief angle, size and thickness, the standardised geometry supports fast changeovers and predictable cutting behaviour on established toolholders.

Geometry tuned for chip control and surface finish

A 0.4 mm corner radius and a single-sided chipbreaker deliver a compromise between edge strength and surface finish: the modest radius enhances finishing capability while the chipbreaker steers chips away from the cutting zone for safer swarf handling. The insert thickness (3.97 mm) contributes to mechanical rigidity, reducing vibration and supporting consistent surface quality in through-feed and interrupted cuts.

Application-oriented material performance

Designed primarily for turning, the insert’s PVD-coated carbide composition makes it a first choice for general-purpose turning of heat-resistant alloys while maintaining versatility across a range of steels and alloys. The single-sided chipbreaker and the option of secure clamping via the central hole with a cylindrical bore and single-sided countersink (40°–60°) ensure stable seating and repeatable performance in both external and internal operations.

FAQ

What materials is the CPMT 09T304 AH8015 insert suitable for?
The CPMT 09T304 AH8015 insert is formulated for turning heat-resistant alloys and performs well in a wide range of steels and alloys due to its balanced PVD-coated carbide grade.

How does the AH8015 grade affect tool life and surface quality?
AH8015 provides a compromise between wear resistance and edge stability, extending tool life under elevated temperatures while supporting consistent surface finish during finishing passes.

Is special clamping required for this insert given the countersink design?
No special method is required; the insert uses a central cylindrical hole with a single-sided countersink (40°–60°) for secure, repeatable clamping in compatible ISO holders.

Can the insert be used for both external and internal turning?
Yes, the geometry and chip control features of this insert make it suitable for both external and internal turning operations, provided the holder matches the ISO form and size.

What is the advantage of the 0.4 mm corner radius?
A 0.4 mm corner radius strengthens the cutting edge for improved durability while still allowing for good surface quality in semi-finishing and finishing operations.
