DPMT 070204 AH8015 — DPMT ISO turning insert for turning, Tungaloy

The DPMT 070204 AH8015 is an ISO-standard rhombic turning insert designed for external and internal turning of heat‑resistant alloys, offering a compact geometry for precise, repeatable machining.

• PVD-coated AH8015 carbide for heat-resistant alloys
• Rhombic insert, size 07 with 55° cutting angle
• 0.4 mm corner radius for improved surface finish
• Single-sided chipbreaker with cylindrical hole

Higher throughput with balanced wear and edge stability

The PVD-coated grade AH8015 combines wear resistance and edge stability, making it particularly suited for machining heat‑resistant alloys where sustained cutting performance is required. The PVD-coated surface reduces adhesive wear and increases tool life under elevated temperatures. Selecting this grade contributes to fewer tool changes and steadier cycle times, supporting reliable production rates and predictable maintenance intervals.

Geometry tuned for consistent surface quality and chip control

The rhombic plate form with a 55° cutting angle and 0.4 mm corner radius delivers a compromise between strength and fine surface finish. A small corner radius helps maintain a sharp cutting edge for accurate profiles, while the single-sided chipbreaker manages swarf evacuation to reduce re-cutting and improve surface integrity. The insert’s cylindrical hole with a 40°–60° countersink ensures secure seating and consistent clamping force for repeatable results.

ISO standardisation simplifies holder selection and system integration

As an ISO-standard insert, compatibility with holders is determined by form, clearance angle, tolerance class, fastening, size and thickness—allowing straightforward integration into existing tool systems. The insert forms part of a system comprising a matching external holder or boring bar, a support pad or clamping kit, and replacement fastening screws. For many workshops, this standardisation reduces setup time and simplifies inventory management while maintaining process reliability.

FAQ

Which materials are best machined with this insert?
The DPMT 070204 AH8015 insert is optimised for heat‑resistant alloys thanks to the AH8015 grade and PVD-coated carbide construction, while still performing well on a broad range of alloyed steels.

How does the 0.4 mm corner radius affect the surface finish?
A 0.4 mm corner radius provides a compromise between edge strength and surface quality, improving finish compared with larger radii while maintaining adequate edge robustness for general turning operations.

Will this insert fit existing holders?
Compatibility depends on ISO form, clearance angle, tolerance class, fastening method, size and thickness; the ISO‑standardised design of this insert simplifies matching to compliant holders, but verification of holder specifications is recommended.

What benefits does the single-sided chipbreaker provide?
The single-sided chipbreaker improves chip formation and evacuation during turning, reducing the risk of re-cutting and helping to maintain consistent surface integrity on interrupted or continuous cuts.

Can this insert be used for internal turning?
Yes — the ISO geometry and compact rhombic form allow use in both external and internal turning applications provided a suitable boring bar or holder is selected.
