CNMG090408 AH8015 ISO turning insert (rhomboid, PVD‑coated) by Tungaloy

A CNMG090408 AH8015 rhombic turning insert for external and internal turning, optimised for heat‑resistant alloys and general turning operations

PVD-coated carbide grade AH8015 ISO CNMG 090408 rhombic insert Double-sided with cylindrical hole Balanced wear resistance and edge stability

Durable grade for heat‑resistant alloys and general turning performance

The AH8015 grade is a PVD‑coated carbide formulation developed as a first choice for machining heat‑resistant alloys. The coating and substrate balance wear resistance with cutting‑edge stability, which reduces unexpected tool changeovers and keeps cycle times predictable. For workshops processing high‑temperature alloys, this insert offers reliable flank and crater wear behaviour that supports longer uninterrupted runs and helps stabilise overall production efficiency.

Geometry and system compatibility that simplify tool selection

With a rhombic form, 0° clearance, an 80° main angle and a 0.8 mm corner radius, the insert delivers a predictable cutting profile and good access for external and internal turning tasks. Compatibility with holders is determined by form, clearance, tolerance class, fixing method, size and thickness; the insert integrates into standard ISO systems alongside a matching outside holder or boring bar, shim/clamping set and spare screws. Clear geometry reduces setup time and simplifies tool inventory management.

Practical benefits for workshop productivity and quality

The double‑sided design and cylindrical locating hole permit economical use and secure clamping, while the nominal thickness of 4.76 mm and insert size 09 provide mechanical stiffness for stable cutting. The balanced edge stability of the grade minimises edge chipping on interrupted cuts and supports consistent surface finish and dimensional accuracy. For operations prioritising repeatability and low variance, this insert contributes directly to improved process control and fewer in‑process rejects.

FAQ

What materials is this insert best suited for?
The CNMG090408 AH8015 insert is formulated for machining heat‑resistant alloys and covers a broad range of general turning applications where a balance of wear resistance and edge stability is required.

How is the insert clamped in the toolholder?
This rhombic, double‑sided insert locates via a cylindrical hole and is secured by the holder’s clamping screw and shim/clamping set compatible with ISO turning systems.

Can the edge radius be used for finishing passes?
The 0.8 mm corner radius provides a compromise between strength and finish; it is suitable for semi‑finishing and programmes that require stable cutting with good surface integrity.

Is the grade PVD coated and what benefit does that bring?
Yes, the AH8015 is PVD‑coated, which enhances wear resistance and helps maintain cutting‑edge integrity during elevated temperatures and sustained cutting.

Which components are required to assemble a working system?
A complete turning system comprises the insert, a matching outside holder or boring bar, the appropriate shim/clamping set and spare screws; compatibility depends on form, clearance, tolerance class, fixing, size and thickness.
