DPMT 070208 AH8015 ISO turning insert, PVD‑coated carbide, 55° rhombic – Tungaloy

The DPMT 070208 AH8015 is an ISO‑norm rhombic indexable insert designed for external and internal turning, offering a balanced mix of wear resistance and cutting‑edge stability for heat‑resistant alloy machining.

• ISO‑normed DPMT 070208 form
• PVD‑coated AH8015 carbide grade
• 55° rhombic geometry, 11° relief angle
• One‑sided chipbreaker for stable chips

High productivity on heat‑resistant alloys with balanced edge life

The PVD‑coated AH8015 grade delivers a balanced combination of wear resistance and cutting‑edge stability, making the insert a solid choice for general machining of heat‑resistant alloys. The coating supports consistent edge behaviour under elevated temperatures, which translates into longer tool life and fewer indexings. In practice, this means steady cycle times and fewer unscheduled tool changes when turning demanding alloys.

Secure clamping and straightforward holder selection

As an ISO‑normed cutting tip, compatibility with a toolholder is governed by form, relief angle, tolerance class, attachment type, size and thickness. Matching these parameters ensures correct seating and repeatable positioning, reducing vibration and runout. For workshops that standardise on ISO inserts, integration into an existing holder inventory is straightforward and supports reliable component tolerances during series production.

Geometry and chip control that protect the cutting edge

The 55° rhombic shape combined with a 0.8 mm corner radius and an 11° relief angle offers a compromise between strength and finishing capability. The single‑sided chipbreaker guides chips away from the cut, improving surface quality and reducing the risk of built‑up edge. The insert’s cylindrical mounting hole with a single‑side countersink (40°–60°) and a plate thickness of 2.38 mm contribute to stable clamping and predictable cutting behaviour during both roughing and finishing passes.

Practical system setup and application advice

The insert forms one element of a complete turning system: indexable insert, matched external holder or boring bar, backing/clamping set and replacement screws. Selection of the appropriate chipbreaker and grade should be guided by the workpiece material, machining operation and machine stability. For standard external and internal turning tasks where heat‑resistant alloys are encountered, this insert represents a pragmatic balance between productivity and edge robustness.
