CNMG090408 AH8015 Tungaloy indexable insert — PVD-coated carbide for turning, 0.8 mm corner radius

The CNMG090408 AH8015 Tungaloy insert is an ISO-indexed turning insert engineered for external and internal turning applications; its ISO CNMG geometry and PVD-coated grade suit machining of heat-resistant alloys.

• ISO CNMG090408 geometry for standard holders
• PVD-coated AH8015 carbide for heat-resistant alloys
• 0.8 mm corner radius for robust cutting edges
• Double-sided insert with cylindrical hole

Consistent cutting performance for demanding turning

The CNMG090408 AH8015 insert combines an ISO CNMG geometry with a PVD-coated AH8015 carbide grade, delivering a balance between wear resistance and edge stability. This composition makes the insert particularly suitable for the general machining of heat-resistant alloys, where thermal loads and edge degradation can limit productivity. The PVD layer reduces adhesive wear and helps maintain a predictable cutting behaviour at elevated temperatures, supporting longer uninterrupted runs and fewer insert changes.

Shop-floor advantages that raise productivity

A double-sided design and the presence of a cylindrical hole for secure clamping reduce tooling cost per cutting edge and simplify indexation. The 0.8 mm corner radius increases resistance to chipping and is advantageous for semi-finish turning where a robust edge improves cycle stability. The ISO standard form ensures broad holder compatibility; selecting the correct holder and clamping kit according to form, clearance and tolerance class enables consistent tool performance and quick changeover.

Practical selection guidance for reliable results

Compatibility depends on holder form, free/relief angle, tolerance class, clamping and plate thickness. The indexable plate is offered in the ISO series intended for turning; a matching outside holder or boring bar, appropriate shim/clamp set and fastening screw complete the system. Choose the chipbreaker and grade to match the workpiece, machining strategy and machine stability — the right combination reduces vibration, improves surface finish and lengthens insert life for predictable, cost-effective production.

FAQ

Is this insert suitable for heat-resistant alloys?
The CNMG090408 AH8015 Tungaloy indexable insert (SKU 6946673-Tungaloy) is specified as a first choice for general machining of heat-resistant alloys due to its balanced wear resistance and edge stability.

Can the insert be used for both external and internal turning?
Yes, the insert is intended for external and internal turning; compatibility with a given holder or boring bar must be checked to ensure proper form, free angle and clamping.

What advantage does the 0.8 mm corner radius offer?
A 0.8 mm corner radius provides a robust cutting edge that resists chipping, improving stability in semi-finish operations and during interrupted cuts.

Is the insert reversible and how does that affect cost?
The insert is double-sided, allowing a second cutting edge to be used after indexing; this reduces cost per edge and extends productive tool life.

How to ensure correct clamping and fit in the holder?
Check holder compatibility against the ISO CNMG090408 form, the relief (free) angle, tolerance class, clamp system and plate thickness; proper clamping and a matching shim or clamp set ensure secure fixation and repeatable performance.
