DCMT11T302 AH8015 ISO rhombic turning insert by Tungaloy — PVD‑coated, 0.2 mm radius

The DCMT11T302 AH8015 is an ISO‑format rhombic insert designed for precision external and internal turning of heat‑resistant alloys, combining wear resistance with cutting‑edge stability for general machining.

• ISO rhombic insert, 55° cutting geometry
• PVD‑coated AH8015 for heat‑resistant alloys
• 0.2 mm corner radius for accurate profiling
• Cylindrical hole with one‑side countersink for secure clamping

Reliable wear resistance with balanced edge stability

The combination of a PVD coating and the AH8015 grade delivers a balance between wear resistance and edge robustness, making this insert well suited to machining heat‑resistant alloys. PVD (physical vapour deposition) forms a thin, hard layer that reduces adhesive and abrasive wear under elevated temperatures; this helps to extend tool life and maintain consistent part quality. The single‑sided chipbreaker minimises built‑up edge and promotes predictable chip formation, which supports efficient material removal and repeatable surface finish.

Secure clamping and geometries that reduce vibration

ISO compatibility is ensured by the standardised geometry: the rhombic form with a 55° cutting angle and 7° relief provides stable cutting engagement, while the 3.97 mm plate thickness and 0.2 mm corner radius aid in producing fine profiles and radiused features. The insert is supplied with a cylindrical hole and a one‑side countersink (40°–60°), allowing secure fastening with appropriate screws and seatings. Stable clamping reduces chatter and improves tool life, which in turn lowers machining downtime and scrap rates.

Practical application guidance for productive turning

Intended for general turning, including both external and internal operations, this insert performs best when the chipbreaker and grade are matched to the workpiece material and machining conditions. The AH8015 grade is recommended as a first choice for many heat‑resistant alloys due to its balanced properties; selecting a stiffer holder and optimised cutting parameters will enhance repeatability and surface integrity. For shops seeking dependable, economical machining, the combination of PVD‑coated carbide, standard ISO sizing and a modest corner radius offers a pragmatic route to consistent results and simplified tool inventory.

FAQ

Is this insert suitable for machining heat‑resistant alloys?
The DCMT11T302 AH8015 insert is specifically recommended for the general machining of heat‑resistant alloys, as the AH8015 grade provides a balanced combination of wear resistance and edge stability.

Which holder characteristics must be checked for correct fit?
Compatibility depends on holder form, relief angle, tolerance class, attachment method, size and plate thickness; the insert conforms to ISO dimensions, so confirm these parameters against the intended external or internal turning holder.

What advantage does the PVD coating offer on this grade?
The PVD coating on the AH8015 carbide reduces adhesive and abrasive wear at elevated temperatures, supporting longer cutting life and more consistent surface quality during continuous turning cycles.

Can the insert be used for both external and internal turning?
Yes — the geometry and neutral chip control make the DCMT11T302 suitable for both external and internal turning when the correct holder and cutting parameters are chosen.

What does the hole and countersink specification mean for clamping?
The cylindrical hole with a one‑sided countersink (40°–60°) allows reliable engagement with standard clamping screws and seats, ensuring secure fixation and reduced risk of insert movement under load.
