SNMG 120408 AH8015 – ISO turning insert by Tungaloy, PVD-coated carbide

SNMG 120408 AH8015 is an ISO‑standard indexable insert for external and internal turning, designed for reliable machining of heat‑resistant alloys.

• PVD-coated carbide grade AH8015
• ISO SNMG120408, square 90° geometry
• Double-sided chipbreaker, secure cylindrical hole
• 0.8 mm corner radius for stable cutting edge

Consistent performance with PVD-coated carbide

The PVD-coated AH8015 grade combines wear resistance and edge stability to deliver consistent results when machining heat‑resistant alloys. The coating increases thermal and abrasive resistance, which supports longer tool life under elevated cutting temperatures. For general turning operations, this balance between hardness and toughness reduces the frequency of insert changes and helps maintain component tolerances without sacrificing surface quality.

ISO conformity and predictable holder compatibility

As an ISO SNMG120408 plate, the insert fits standard square holders when the holder’s form, relief angle, tolerance class, fastening method, size and plate thickness match. The ISO designation simplifies procurement and toolroom logistics, while the clear indication of geometry and fit promotes predictable set‑up times. Where clamping accuracy and clearance angles are controlled, the result is repeatable tool position and reduced set‑up variability.

Edge geometry engineered for stability and surface quality

The square form with a 90° included angle and a 0.8 mm corner radius provides a robust cutting edge that supports medium to heavy roughing as well as finishing passes, depending on the cutting data. The double‑sided chipbreaker design helps control chip formation across a range of feeds, improving evacuation and reducing the risk of built‑up edge on difficult alloys. Together, these features contribute to a consistent surface finish and fewer reworks.

Practical benefits for workshop productivity

With a plate thickness of 4.76 mm and a cylindrical hole for secure fastening, the insert is straightforward to index and reuse, reducing downtime. The combination of square geometry and a PVD carbide substrate enables broad material coverage while simplifying inventory: one insert type addresses multiple turning tasks. For production environments seeking stable process windows and lower tooling costs per component, the design supports higher productivity and predictable component quality.

FAQ

What materials is this insert best suited for?
The SNMG 120408 AH8015 insert is optimised for machining heat‑resistant alloys thanks to the PVD‑coated AH8015 carbide, offering a balance of wear resistance and edge strength.

How does the 0.8 mm corner radius affect performance?
A 0.8 mm corner radius improves edge robustness and allows stable cutting under variable loads, helping to extend insert life while maintaining acceptable surface quality.

Is this insert compatible with standard SNMG holders?
Yes, the ISO SNMG120408 designation indicates compatibility with standard holders, provided the holder’s form, relief angle, tolerance class, fastening and thickness match the insert specifications.

Can the insert be indexed to present a fresh cutting edge?
The square form and double‑sided chipbreaker permit indexing to further cutting edges, enabling efficient reuse and reducing tooling change intervals.

What fastening type does the plate require?
The insert features a cylindrical hole for secure clamping; correct fastening is essential to achieve the ISO‑specified positional stability.
