DCMT 070202 AH8015 ISO turning insert — Tungaloy

DCMT 070202 AH8015 is an ISO rhombic turning insert designed for general turning applications, engineered to balance wear resistance and cutting-edge stability for heat-resistant alloys.

• PVD-coated carbide AH8015 for heat-resistant alloys
• Rhombic ISO insert, size 07, radius 0.2 mm
• 7° relief and 55° geometry for stable cutting
• One-sided chipbreaker, countersunk hole

Higher productivity through material and coating benefits

The PVD-coated carbide grade AH8015 is formulated as a first choice for the general machining of heat-resistant alloys, offering a balanced compromise between wear resistance and edge strength. This balance enables moderately higher cutting speeds and extends tool life compared with uncoated grades, translating into reduced tool-change frequency and improved process economics. The combination of coating technology and carbide substrate helps to maintain a consistent edge geometry under thermal load, which is particularly advantageous where stability of cut and component tolerances are critical.

Predictable fit and wide applicability for turning operations

As an ISO-standard rhombic insert, the plate is compatible with a broad range of external holders and boring bars; compatibility is determined by form, relief angle, tolerance class, fixation method, size and thickness. The rhombic shape and 55° included angle support both external and internal turning operations, while the one-sided chipbreaker improves chip formation and evacuation in interrupted and continuous cuts. The insert’s hole arrangement — cylindrical hole with a single-sided countersink (40°–60°) — supports secure clamping and repeatable seating in standard clamping systems, reducing the risk of misalignment and enabling consistent machining results.

Operational reliability and handling advantages on the shop floor

Key geometry values such as the 0.2 mm corner radius and the plate thickness of 2.38 mm contribute to edge robustness and enhanced surface finish when machining thin-walled or heat-resistant components. The 7° relief angle reduces rubbing at the flank, lowering cutting temperature and vibration under many turning conditions. Chip control benefits from the dedicated chipbreaker geometry, which aids in forming manageable chips and reduces tool nose wear. Together, these characteristics support a reliable, repeatable process that is easy to integrate into existing tool inventories and production routines.

FAQ

What materials is this insert intended for?
The DCMT 070202 AH8015 insert is optimised for the general machining of heat-resistant alloys while also providing balanced performance across a broad range of materials when appropriate cutting data are used.

Which holders are compatible with this ISO insert?
Compatibility depends on holder form, relief angle, tolerance class, fixation and plate thickness; the rhombic ISO geometry and the cylindrical hole with countersink ensure secure seating in standard clamping systems designed for DCMT-type inserts.

How does the AH8015 grade affect tool life and cutting speed?
The PVD-coated AH8015 grade combines wear resistance and edge stability to permit stable cutting at elevated speeds compared with uncoated grades, often resulting in longer tool life and fewer tool changes in production environments.

What benefit does the one-sided chipbreaker provide?
The one-sided chipbreaker improves chip formation and evacuation, promoting safer chip control and reducing risk of entanglement or build-up, which supports consistent surface finish and tool performance.

Is this insert suitable for internal boring as well as external turning?
Yes; the rhombic shape and 55° geometry make the insert suitable for both external and internal turning operations when used with the corresponding holders and correct cutting parameters.
