DCMT070204 AH8015 — ISO turning insert, 55° rhombic (Tungaloy)

The DCMT070204 AH8015 is a rhombic ISO insert for external and internal turning, optimised for general machining of heat‑resistant alloys.

• ISO-compliant 55° rhombic geometry
• PVD-coated carbide AH8015 grade
• 0.4 mm corner radius for precision
• Single-sided chipbreaker with through-hole

Higher productivity through balanced grade and coating

The combination of the AH8015 grade and a PVD-coated carbide surface delivers a balanced mix of wear resistance and cutting-edge stability that benefits serial and jobbing environments. The coating reduces adhesion and improves thermal resistance during interrupted cuts, which in turn extends usable life and reduces tool-change frequency. For operations that prioritise throughput, this balance yields fewer unplanned stops and a more consistent machining rhythm.

Reduced set-up time with standardised geometry

Conformance to ISO dimensions and the 55° rhombic geometry ensures straightforward interchangeability with compatible holders. The standardised form, clearance angle and tolerance class simplify insert selection and reduce set‑up time while maintaining repeatable results. With a 0.4 mm corner radius and a 2.38 mm thickness, the insert provides predictable cutting forces and enables reliable component tolerances when used in appropriately rated toolholders.

Controlled chip formation and dependable surface quality

The single-sided chipbreaker and the specified hole with a cylindrical bore plus a one-sided countersink (40°–60°) support stable clamping and consistent chip control in turning applications. This configuration promotes a consistent surface finish and stable cutting behaviour when machining alloys that can produce long, stringy chips. In practice, the system—comprising the ISO insert, the correct external holder or boring bar, a backing shim/clamping set and replacement screws—ensures both security and repeatable performance.

Clear application scope and system considerations

Designed primarily for turning, the insert is a suitable first choice for general machining of heat‑resistant alloys where a compromise between edge life and toughness is required. Compatibility with a specific holder is determined by form, clearance angle, tolerance class, clamping method, size and thickness; matching these parameters avoids fitment issues and secures the expected performance.
