DPMT 070208 AH8015 Tungaloy indexable turning insert — ISO rhombic 55° geometry, PVD-coated carbide

The DPMT070208 AH8015 insert is an ISO-standard indexable turning insert designed for external and internal turning, optimised for heat‑resistant alloys and general turning tasks

• ISO rhombic 55° geometry
• PVD-coated carbide AH8015
• 0.8 mm corner radius for robust edge
• Single-sided chipbreaker with countersink

Reliable chip control with rhombic 55° geometry

The rhombic 55° profile delivers a balanced cutting angle that reduces radial loads while maintaining accessibility for shoulder and profile turning. The combination of ISO-standard geometry and a single-sided chipbreaker yields consistent chip formation; the chipbreaker directs swarf away from the cutting zone, lowering the risk of re-cutting and contributing to longer toolfixture life. For users unfamiliar with chipbreaker design, this means fewer interruptions from clogged chips and more predictable machining cycles.

Balanced grade for heat‑resistant alloys and general turning

The AH8015 grade is a PVD-coated carbide optimised as a first choice for machining heat‑resistant alloys. It balances wear resistance and edge stability, which supports longer continuous cuts and reduces frequency of insert changes. In practice, this grade helps to maintain surface finish and dimensional control during medium-duty turning operations, allowing for consistent throughput without resorting to overly conservative cutting parameters.

Secure clamping and simple mounting for production use

The insert is supplied with a cylindrical hole and a one‑sided countersink (40°–60°), enabling reliable centring and secure clamping in standard holders or boring bars. The plate thickness of 2.38 mm and the size designation 07 align with widely used ISO holders, making retrofitting straightforward where form, relief angle and tolerance class match. Clear compatibility reduces setup time and minimises the need for special fixtures, which supports efficient shopfloor workflows.

Robust edge preparation for repeatable results

With a 0.8 mm corner radius the cutting edge gives enhanced stability under variable feed, improving resistance to chipping during interrupted cuts or unstable clamping conditions. Edge preparation combined with the PVD coating mitigates adhesion and built‑up edge when machining sticky or work‑hardening alloys, thereby preserving geometry and helping to achieve repeatable part quality with fewer reworks.

FAQ

What materials is this insert suited for?
The insert with grade AH8015 is intended primarily for heat‑resistant alloys and general turning operations; it provides a compromise between wear resistance and edge stability for such materials.

How does the 55° rhombic geometry affect machining?
A rhombic 55° geometry reduces radial cutting forces and improves access for shoulder and profile turning, which benefits process stability when using this insert.

Is the insert compatible with standard ISO holders?
The ISO designation DPMT070208 and the size 07 are designed to fit compatible ISO holders when form, relief angle and tolerance class match; the cylindrical hole with countersink supports secure clamping.

What is the benefit of the AH8015 PVD coating?
The PVD-coated AH8015 grade enhances wear resistance and reduces adhesion on the cutting edge, improving performance during continuous cuts in demanding alloys.

Can the 0.8 mm corner radius be used for finishing passes?
A 0.8 mm corner radius is primarily chosen for robust edge stability; for fine finishing, a smaller radius may provide better surface finish depending on the application.
