SNMG120402 AH8015 ISO turning insert — PVD-coated carbide by Tungaloy

The SNMG120402 AH8015 is an ISO-standard square indexable insert for general turning applications, optimised for machining heat-resistant alloys.

• ISO SNMG 120402 form, 12 mm square
• PVD-coated carbide AH8015
• Balanced wear resistance and edge stability
• Double-sided chipbreaker, 0.2 mm corner radius

Reliable performance on heat-resistant alloys

The AH8015 grade is a PVD-coated carbide developed as a first choice for the general machining of heat-resistant alloys. Its composition offers a measured compromise between wear resistance and edge stability, which translates into longer effective cutting periods and fewer unscheduled insert changes. The coating reduces adhesive wear at elevated temperatures and improves resistance to crater wear; this results in steadier cutting forces and more consistent part quality when turning demanding alloys on conventional and CNC lathes.

Consistent holder compatibility for predictable setups

As an ISO SNMG insert, compatibility with toolholders is determined by form, clearance angle, tolerance class, fastening, size and thickness. The square 12 mm format with a 4.76 mm thickness and a nominal 0.2 mm corner radius suits many external holders and boring bars. The insert features a cylindrical hole and a 90° included angle, with a listed clearance angle of 0°; selecting a matching holder and correct clamping set is essential for secure fixation and repeatable concentricity. Correct pairing reduces vibration, preserves the cutting edge and supports reproducible surface finish.

Better chip control and economical use at the machine

The double-sided chipbreaker design delivers effective chip control across a range of cutting conditions, helping to prevent entanglement and improving shop-floor safety. Being double-sided also provides an economic benefit: the insert can be indexed to present a fresh cutting edge, lowering cost per cutting edge compared with single-use solutions. The balanced geometry promotes a good surface finish in both external and internal turning operations, while the moderate corner radius supports light interrupted cuts and general-purpose profiling.

Metav Werkzeuge can advise on matching holders, clamping sets and cutting parameter windows to align the insert’s strengths with specific machine set-ups and workpiece materials; if in doubt, ask for the suitable chipbreaker and grade for the intended machining task.

FAQ

What materials is this insert designed for?
The SNMG120402 AH8015 insert is intended primarily for the general turning of heat-resistant alloys; the AH8015 grade provides a balance of wear resistance and edge stability suitable for such materials.

How is the insert fixed to a holder?
The insert uses a cylindrical hole and is secured by the holder’s clamping system; compatibility depends on form, clearance, tolerance class, fastening type, size and thickness.

Can the insert be used for both external and internal turning?
Yes, the geometry and chipbreaker make the insert suitable for both external and internal turning when paired with an appropriate external holder or boring bar.

What advantage does the double-sided chipbreaker offer?
The double-sided chipbreaker enables indexing to fresh edges and improves chip control, which lowers operating costs and enhances process reliability.

Is the AH8015 coating suitable for high-temperature cutting?
The PVD-coated AH8015 grade is formulated for improved performance on heat-resistant alloys and offers enhanced resistance to adhesive and crater wear at elevated temperatures.
