SNMG120408 AH8015 Tungaloy — ISO turning insert for heat-resistant alloys

The SNMG120408 AH8015 is a square ISO turning insert designed for external and internal turning of heat-resistant alloys, offering a stable cutting edge and reliable chip control.

• SNMG120408 ISO square insert for turning
• PVD-coated carbide grade AH8015 for alloys
• Double-sided chipbreaker for stable chips
• 0.8 mm corner radius, 90° cutting geometry

Reliable cutting performance for heat-resistant alloys

The PVD-coated AH8015 carbide grade combines wear resistance and edge stability to deliver predictable tool life when machining heat-resistant materials. This grade is selected for its balanced properties, reducing unexpected tool changes and supporting a steady production rhythm. The insert’s PVD coating increases resistance to oxidation at elevated cutting temperatures, which benefits process stability and minimises thermal edge degradation during longer or rougher passes.

Stable chip control and secure clamping for consistent results

A double-sided chipbreaker and indexable design enable repeatable chip formation and efficient evacuation, which improves surface finish and reduces risk of built-up edge. The insert’s compatibility with holders is determined by shape, clearance angle, tolerance class, fastening, size and thickness; matching these parameters to the toolholder ensures secure clamping and consistent cutting performance. The cylindrical hole and the standard 90° cutting geometry contribute to reliable seat location and predictable cutting forces in turning applications.

ISO interchangeability and economical machining

As an ISO standard insert with 4.76 mm thickness and a square form, the component is easy to replace and index, supporting quick changeovers and reduced downtime. The 0.8 mm corner radius provides a robust edge for moderate depth-of-cut operations while still allowing acceptable surface quality. System integration is straightforward: the insert works within the common system setup of insert, compatible outer holder or boring bar, shim/clamping set and replacement screws, enabling pragmatic retrofitting into existing toolsets and promoting economical, productive machining.

FAQ

What materials is this insert best suited for?
The SNMG120408 AH8015 Tungaloy insert is formulated for machining heat-resistant alloys and other demanding materials where a balance of wear resistance and edge stability is required.

How does the AH8015 grade benefit production?
AH8015, as a PVD-coated carbide, provides extended resistance to elevated temperatures and wear, which helps the Tungaloy insert maintain dimensional stability and reduce unexpected tool changes during continuous operation.

Can the SNMG120408 be used in existing ISO holders?
Yes — the SNMG120408 conforms to ISO dimensions; compatibility depends on matching the holder by form, clearance angle, tolerance class, fastening, size and thickness to ensure secure clamping and correct seat location.

What advantages does the double-sided chipbreaker provide?
The double-sided chipbreaker on this insert promotes stable chip formation and easier evacuation, improving surface finish and reducing the likelihood of chip-related interruptions in turning operations.

How many indexable edges does the insert offer and what is the effect on costs?
As a square, indexable insert with a double-sided design, the SNMG120408 AH8015 Tungaloy insert offers multiple usable cutting edges, enabling indexation and extending tool life, which supports lower tooling costs per component over time.
