SNMG 120408 AH8015 Tungaloy turning indexable insert

The SNMG120408 AH8015 is an ISO-standard turning indexable insert engineered for general external and internal turning of heat‑resistant alloys.

• PVD-coated carbide grade AH8015
• ISO SNMG 120408 geometry, 90° form
• 0.8 mm corner radius for stable cutting
• Double-sided insert with cylindrical hole

High‑temperature alloy performance with balanced edge stability

The SNMG120408 AH8015 is supplied in the AH8015 cutting grade, a PVD-coated cemented carbide designed as a first choice for machining heat‑resistant alloys. The coating provides a barrier against thermal and abrasive wear, while the substrate supports mechanical strength; this combination yields predictable tool life and consistent component tolerances. For production environments where cycle time and part repeatability matter, the balanced mix of wear resistance and edge stability reduces unscheduled insert changes and supports uninterrupted throughput.

Geometry and clamping that secure process reliability

The square, 90° insert form and the 0.8 mm corner radius deliver a stable cutting edge suitable for a range of turning tasks. The insert is double‑sided and presented with a cylindrical hole, enabling secure clamping and economical indexability. Compatibility with a holder depends on form, relief angle, tolerance class, fastening method, size and thickness; matching these parameters ensures correct seating and repeatable cutting forces, thereby enhancing surface finish and dimensional control during machining.

Chip control and productivity advantages

Equipped with a chipbreaker profile tailored to general turning, the insert supports controlled chip formation and evacuation even when cutting difficult alloys. The PVD-coated surface also eases built‑up edge tendencies and improves heat dispersion from the cutting zone. These attributes translate into higher effective productivity: longer intervals between indexings, fewer tool changes and more predictable machining windows. Where batch processing demands consistent output, this insert contributes directly to reduced cycle times and lower unit costs.

System setup and recommended applications for efficient use

Intended for both external and internal turning, the insert functions as part of a system consisting of an ISO indexable insert, a compatible external holder or boring bar, a shim/underlay, clamp set and replacement screws. For best results, select the chipbreaker and grade to match workpiece material, machining type and machine stability. The geometry and coating make this insert especially suitable when machining high‑temperature alloys that require a compromise between cutting edge robustness and abrasion resistance.

FAQ

Which materials are suitable for this insert?
The SNMG120408 AH8015 insert from Tungaloy is intended primarily for machining heat‑resistant alloys and other materials where a balance of wear resistance and edge stability is required.

Is this insert compatible with standard SNMG holders?
Compatibility depends on holder form, relief angle, tolerance class, fastening method, size and thickness; the insert follows the ISO SNMG120408 specification and is designed for standard SNMG clamping systems.

How does the AH8015 grade affect tool life?
The AH8015 PVD coating improves resistance to thermal and abrasive wear while the carbide substrate maintains edge strength, resulting in longer usable life and more consistent cutting performance under demanding conditions.

Can the insert be rotated to use multiple cutting edges?
Yes, the square double‑sided design allows indexing to fresh cutting edges, enabling economical use of all available faces for extended service life.

What system components are required for correct installation?
A suitable external holder or boring bar, a shim/underlay, the correct clamp set and replacement screws are required to assemble the complete system with this insert.
