CNMG190616 AH8015 — ISO turning indexable insert, PVD‑coated carbide, Tungaloy

CNMG190616 AH8015 is an ISO‑standard rhombic insert engineered for external and internal turning of heat‑resistant alloys in general machining operations.

• PVD‑coated carbide AH8015
• ISO‑standard CNMG190616 form
• 0° clearance, 80° rhombic geometry
• Double‑sided insert with cylindrical hole

Consistent edge life for hard‑to‑cut materials

The AH8015 grade is a PVD‑coated carbide specifically balanced for machining heat‑resistant alloys. The coating improves wear resistance while the substrate maintains edge stability, so the insert sustains cutting performance longer under elevated temperatures. This balance reduces the frequency of index changes and tool changes, which leads to more predictable cycle times and a lower cost per component in batch production. For operations that require a compromise between abrasive resistance and chipping avoidance, this grade offers a reliable middle ground.

Geometry and dimensions that support rigidity and repeatability

The rhombic shape with an 80° included angle and 0° clearance provides a stable cutting orientation suitable for a wide range of turning tasks. Key dimensions — 19 mm inscribed circle, 6.35 mm thickness and a 1.6 mm corner radius — increase the contact area with the toolholder, improving rigidity and enabling higher metal removal rates where fixturing and machine stiffness permit. The cylindrical centre hole ensures repeatable clamping and accurate positioning in compatible holders; compatibility depends on form, clearance, tolerance class, fastening method, size and thickness, so confirm fitment with the chosen outside holder or boring bar.

Process advantages and recommended system setup

Designed as a double‑sided insert with an integrated chipbreaker, this grade supports cost‑effective turning by providing two usable edges per index position. Typical applications include both external and internal turning; select the chipbreaker and grade to match the workpiece material, machining strategy and assembly stability. The complete system comprises the ISO insert, a matching outside holder or boring bar, a support shim or clamp set and replacement screws for secure fixing. Using this configuration helps to improve surface finish consistency and overall productivity, especially in serial production where process stability is essential.

FAQ

What materials is this insert best suited for?
The CNMG190616 AH8015 insert from Tungaloy is optimised for heat‑resistant alloys, offering a balanced combination of wear resistance and cutting‑edge stability for general machining tasks.

How does the insert’s 1.6 mm corner radius affect machining?
A 1.6 mm corner radius on the CNMG190616 AH8015 increases edge strength and contributes to improved surface finish and part integrity when turning with appropriate feed and speed settings.

Is the insert reversible and how many cutting edges are available?
The CNMG190616 AH8015 is double‑sided, providing multiple indexed edges per insert which reduces tooling costs per edge and extends the effective service life in production.

Which toolholder characteristics must be checked for compatibility?
Compatibility depends on the insert form and dimensions; ensure the selected holder matches the CNMG190616 form, 0° clearance, tolerance class, clamping style and the 6.35 mm plate thickness for secure and repeatable mounting.
