DPMT11T308 AH8015 — ISO turning insert, PVD‑coated carbide (Tungaloy)

The DPMT11T308 AH8015 is an ISO‑standard indexable insert engineered for efficient external and internal turning of heat‑resistant alloys.

• DPMT11T308 ISO insert, 55° rhombic
• AH8015 PVD‑coated carbide for heat‑resistant alloys
• 11° clearance, 0.8 mm corner radius
• Cylindrical hole with single‑side countersink

Increased productivity through balanced grade and geometry

The combination of the AH8015 grade and PVD‑coating on a carbide substrate delivers a controlled compromise between wear resistance and edge stability, which directly supports longer cutting intervals and more consistent surface finish in demanding alloys. The rhombic 55° seating offers versatile engagement for both light profiling and medium‑depth turning, while the 0.8 mm corner radius reduces the risk of chipping on interrupted cuts. This balance is particularly beneficial where cycle time and repeatability are priorities, translating technical specification into measurable production gains.

Secure clamping and ISO compatibility for reliable setup

Compatibility with standard holders is determined by form, relief angle, tolerance class, fastening method, size and thickness; the ISO designation guarantees straightforward matching to ISO‑compliant external holders or boring bars. The insert’s cylindrical hole with a one‑sided countersink (40°–60°) ensures positive seating and stable fastening, reducing vibration and improving tool life. The nominal 3.97 mm thickness and standardised geometry simplify inventory and reduce setup time across mixed fleets of ISO holders.

Grade and coating explained for practical decision making

The AH8015 sort is specified as a first choice for general machining of heat‑resistant alloys, offering an even compromise between flank wear resistance and cutting edge support. The PVD surface treatment enhances surface hardness and thermal barrier properties without excessively reducing toughness, making the grade suitable for a wide range of thermal loads. For customers with limited metallurgical experience, this means a robust everyday option that reduces the need for frequent re‑selection and supports process stability.

Choosing the right chipbreaker and application notes

This insert is supplied with a single‑side chipbreaker suitable for a range of turning operations; selection of chipbreaker and grade should be matched to workpiece material, cutting mode and machine stability for optimal results. The ISO‑format insert is intended for both external and internal turning; in unstable setups, a smaller depth of cut and conservative feed help protect the cutting edge, while stable machines can exploit the insert’s balanced properties to increase material removal rate. Clear documentation of holder compatibility prevents mismatches and supports consistent machining outcomes.

FAQ

What materials is this insert suitable for?
The DPMT11T308 AH8015 insert is engineered primarily for heat‑resistant alloys; the AH8015 grade balances wear resistance and edge stability to perform well in such materials.

How does the insert secure to a holder?
The insert uses a cylindrical hole with a one‑sided countersink; correct matching of holder form, tolerance and fastening ensures secure seating for the DPMT11T308 AH8015.

Which geometric details are most relevant for holder compatibility?
Seating angle (55°), relief angle (11°), plate thickness (3.97 mm) and plate form are the decisive parameters when selecting a compatible ISO holder for this indexable insert.

Is the AH8015 coating suitable for interrupted cuts?
The AH8015 PVD‑coated carbide provides a compromise between toughness and wear resistance, offering improved resistance to chipping compared with harder, more brittle coatings; it is therefore a practical option for many interrupted turning tasks.

What is the corner radius and how does it affect the finish?
The insert has a 0.8 mm corner radius; this radius improves edge strength and contributes to a better surface finish on medium‑feed turning passes.
