CCMT 09T308 AH8015 indexable turning insert — PVD-coated carbide for turning (Tungaloy)

A CCMT09T308 AH8015 indexable insert designed for ISO-compliant external and internal turning of heat-resistant alloys, offering a balanced combination of wear resistance and cutting-edge stability for productive machining.

• PVD-coated AH8015 carbide for wear resistance
• ISO CCMT 09T308 form, rhombic plate 09
• 0.8 mm corner radius with 7° clearance
• Cylindrical hole with single-side countersink
• One-sided chipbreaker for stable chip control

High-performance grade for heat-resistant alloys

The PVD-coated AH8015 grade is engineered as a first-choice solution for the general machining of heat-resistant alloys. The PVD-coated surface enhances wear resistance while the underlying carbide substrate maintains edge toughness, producing a balance between tool life and edge stability. This specification reduces the frequency of insert changes and supports consistent cycle times, making it suitable where repeatable performance and reduced downtime are required.

Precise ISO form and secure mounting for reliable repeatability

Manufactured to ISO geometry as CCMT 09T308, the insert features a rhombic plate format with a plate size of 09 and thickness of 3.97 mm, ensuring compatibility with standard ISO holders. The cylindrical hole with single-side countersink (40°–60°) permits secure clamping and predictable seating; combined with the 7° clearance angle and 0.8 mm corner radius, this yields controlled engagement with the workpiece and predictable tool behaviour under varying feed and depth-of-cut conditions.

Controlled chips and consistent surface quality

Equipped with a one-sided chipbreaker, the insert promotes orderly chip formation and evacuation during both external and internal turning operations. Improved chip control contributes directly to surface finish consistency and reduced risk of re-cutting or entanglement, translating into fewer interruptions and higher throughput. The chipbreaker geometry is matched to the grade to maintain a stable cutting edge even when encountering temperature-sensitive alloys.

System-level efficiency and practical assembly

The insert forms part of an ISO-based system comprising a matching external holder or boring bar, clamping pad and screws; correct selection of holder geometry, tolerance class and fastening ensures full benefit from the insert’s design. The balanced combination of AH8015 grade and the insert geometry supports lower overall tooling cost per component by extending service intervals and simplifying tool inventory through wide material applicability.

FAQ

What materials is this insert intended to machine?
The CCMT09T308 AH8015 insert is optimised for machining heat-resistant alloys and general turning tasks where a balance of wear resistance and edge stability is required.

How does the AH8015 grade affect tool life?
The AH8015 PVD-coated carbide grade delivers enhanced wear resistance while maintaining cutting-edge stability, resulting in extended tool life and more consistent production runs with the Tungaloy turning insert.

Which holder types are compatible with this insert?
Compatibility depends on holder form, free angle, tolerance class, fastening method, size and thickness; the ISO CCMT form permits use with standard ISO external holders and boring bars designed for 09-sized rhombic plates.

What is the purpose of the single-side countersink on the hole?
The cylindrical hole with a single-side countersink (40°–60°) ensures correct seating and secure clamping, supporting repeatable insert location and stable cutting conditions.

Can this insert be used for internal turning as well as external turning?
Yes, the geometry and chipbreaker design make the insert suitable for both external and internal turning applications, provided the selected holder offers appropriate support and rigidity.
