CNMG 120402 AH8015 indexable turning insert for Drehen by Tungaloy

CNMG120402 AH8015: an ISO‑format indexable insert engineered for general turning applications, especially suited to heat‑resistant alloys.

• PVD-coated carbide AH8015 for heat-resistant alloys
• Rhombic form with 80° approach angle
• Double-sided chipbreaker for economical indexing
• 0.2 mm corner radius for balanced edge strength

Consistent performance on heat‑resistant alloys

The grade is a PVD-coated carbide AH8015, selected as a first choice for the general machining of heat‑resistant alloys. The coating improves surface hardness and wear resistance, which translates into longer tool life under high temperatures and reduced flank wear. For production environments this means fewer insert changes and higher process stability; the technical balance between wear resistance and edge stability supports repeatable results in series turning.

Geometry and holder compatibility explained

Compatibility with the toolholder depends on the insert form, 0° relief angle, tolerance class, clamping method, size and thickness. The rhombic shape and 80° approach angle offer a universal geometry for both axial and radial engagements, while the standard ISO format simplifies sourcing and holder selection. When choosing a holder, match the plate thickness of 4.76 mm and the size designation to ensure secure clamping and correct cutting line.

Robust cutting edge and chip control for productivity

A 0.2 mm corner radius provides a compromise between edge strength and finish. Combined with a double-sided chipbreaker, the insert enables controlled chip formation across a range of cutting conditions. This yields efficient evacuation of swarf and consistent surface quality in both outer and inner turning operations. The two usable cutting edges per side improve economy without compromising the stable cutting edge required for interrupted cuts or tougher alloys.

Practical selection and machining guidance

Choose the chipbreaker and grade depending on the workpiece material, machining type and set‑up stability. For moderate to high cutting speeds the PVD-coated carbide performs reliably; for very unstable set‑ups favour larger radii and reduced depths of cut. Because the insert is ISO‑format, replacement and reordering follow standard industrial practice, simplifying inventory management and operator training. Where high process reliability is critical, selecting the appropriate insert geometry reduces scrap and increases throughput.
