CNMG 120408 AH8005 Turning Insert — ISO rhombic, 0.8 mm radius, Tungaloy

CNMG120408 AH8005 indexable turning insert for external and internal turning of demanding materials in ISO-compatible tool systems

• PVD-coated carbide AH8005 for high wear resistance
• ISO rhombic CNMG form with 0° clearance angle
• 0.8 mm corner radius for stable cutting results
• Double-sided chipbreaker with cylindrical hole

Reliable wear resistance for heat-resistant alloys and hard materials

The insert's PVD coating on a carbide substrate provides a combination of surface hardness and thermal stability that reduces flank wear under elevated cutting temperatures. This makes the component particularly suited to machining heat-resistant alloys and tougher steels where conventional grades wear prematurely. Fewer insert changes translate into longer uninterrupted running times and a more predictable production rhythm. The coating also improves resistance to built-up edge formation, which supports consistent dimensional accuracy during longer turning cycles.

Geometry and clamping for predictable cutting behaviour

The rhombic geometry and the inclusion of a 0.8 mm corner radius deliver a balance between edge strength and form accuracy, enabling stable chip formation in many turning operations. The 0° clearance angle reduces radial cutting forces in certain set-ups, while the cylindrical hole and standard ISO form ensure secure seating in compatible holders. Compatibility depends on holder shape, clearance, tolerance class, fastening method, size and thickness; confirming these parameters prevents assembly issues and secures repeatable performance at the toolpost.

Practical efficiency and straightforward handling in production

As a double-sided indexable insert, the component permits economical rotation to a fresh cutting edge once wear occurs, effectively doubling service life for each insert body and reducing tooling costs per part. The ISO-series design supports rapid replacement with standard screws and clamping kits, minimising downtime. For users less familiar with indexable tooling: an insert is a replaceable cutting tip mounted in a holder, offering fast edge changes without regrinding. Selecting the appropriate chipbreaker and grade for the workpiece and machining stability is key to maximising tool life and surface quality.

FAQ

What materials is this insert suitable for?
The CNMG120408 AH8005 insert is formulated for machining heat-resistant alloys and harder workpiece materials, offering improved wear resistance under elevated temperatures.

How does the double-sided design affect tool life?
The double-sided configuration allows rotating the insert to a second cutting edge, effectively extending service life and reducing the number of inserts required for a given production run.

Is this insert compatible with standard CNMG holders?
Yes; the insert follows ISO CNMG dimensions and seats in holders that match the form, tolerance class, fastening method, size and thickness specified by ISO standards.

What is the benefit of the 0.8 mm corner radius?
A 0.8 mm corner radius increases edge robustness for interrupted cuts and improves stability, helping to maintain dimensional accuracy during heavier or less stable turning operations.

How should the chipbreaker be matched to the application?
Selecting a chipbreaker tailored to the workpiece material and machining stability is essential; the double-sided chipbreaker on this insert aids consistent chip control across a range of turning tasks.
