SNMG 120408 AH8015 Turning Insert — PVD‑coated carbide, 90° square, Tungaloy

The SNMG120408 AH8015 is an ISO‑standard square indexable turning insert designed for external and internal turning, optimised for machining heat‑resistant alloys.

• PVD‑coated carbide for heat resistance
• Double‑sided with 0.8 mm corner radius
• Cylindrical centre hole for secure clamping
• ISO SNMG form with 90° square geometry

Higher productivity through balanced grade and coating

The combination of the AH8015 grade and a PVD‑coated carbide substrate provides a practical balance between wear resistance and cutting‑edge stability, which reduces downtime from frequent index changes. The PVD layer acts as a hard, thin barrier against abrasive wear and chemical attack at elevated temperatures; as a result, tool life is extended under interrupted cuts and elevated cutting speeds. This makes the insert particularly suitable where consistent cycle times and predictable tool behaviour are priorities in production.

Faster setup and consistent clamping with ISO compatibility

Adherence to the ISO designation ensures straightforward interchangeability: the SNMG120408 geometry, 90° square form and a cylindrical centre hole match a wide range of holders when matched for form, relief angle, tolerance class, fastening and thickness. The insert is double‑sided, offering economical use of cutting edges, while the defined 0° relief angle and a 0.8 mm corner radius deliver a consistent cutting profile. These specifications lower setup time and support reproducible results across batches, which benefits process planning and tool inventory control.

Practical guidance for workshop selection and machining

For external and internal turning of heat‑resistant alloys, select the SNMG120408 variant with the double‑sided chipbreaker suited to the workpiece material and the required surface finish. The square geometry with a 90° cutting angle is advantageous for shoulder cuts and general turning operations, providing robust support against vibration. Where higher temperature resistance is needed, the PVD coating and AH8015 grade help to maintain edge integrity; choose compatible clamping hardware and replace screws and underplates as specified to secure repeatable performance.

FAQ

What materials is this insert intended for?
The SNMG120408 AH8015 insert is specified as a first choice for the general machining of heat‑resistant alloys, offering a balance of wear resistance and edge stability for such materials.

Will the SNMG120408 fit my existing SNMG holder?
Compatibility is determined by form, relief angle, tolerance class, fastening, size and thickness; the ISO‑standard SNMG120408 form and cylindrical centre hole ensure fit with holders specified for that geometry.

What advantage does the PVD coating provide?
The PVD coating on the AH8015 grade offers improved resistance to abrasive wear and heat, extending tool life and maintaining cutting‑edge performance in demanding conditions.

Is the insert reversible or single‑use per side?
The insert is double‑sided, which allows use of both faces; correct indexing and clamping are essential to achieve the intended number of usable cutting edges.

Which operations are most suitable for this insert?
Designed for external and internal turning, the square SNMG geometry with 90° cutting angle is well suited to shoulder cuts and general turning where robustness and repeatability are required.
