SNMG 120412 AH8015 Tungaloy indexable insert — for turning, ISO square 90° geometry, 1.2 mm corner radius

SNMG120412 AH8015 is an ISO-standard square indexable insert designed for external and internal turning of heat-resistant alloys, offering a balanced mix of wear resistance and cutting-edge stability in a PVD-coated carbide grade.

• ISO-standard SNMG geometry for universal holders
• PVD-coated AH8015 for heat-resistant alloys
• Double-sided with 90° square form
• 1.2 mm corner radius for versatile finishing

High productivity on heat-resistant alloys through balanced grade design

The PVD-coated carbide grade AH8015 combines wear resistance with edge stability to deliver consistently productive machining of heat-resistant alloys. In practice, this means longer tool life and fewer interruptions for insert changes, which increases uptime on the machine. The coating stabilises the cutting edge at elevated temperatures while the carbide substrate maintains toughness, so the insert sustains good performance under intermittent or continuous cutting. For processes where cycle time and repeatability matter, this grade reduces the need for frequent rework and supports predictable output.

Straightforward compatibility and secure clamping for predictable results

Designed to ISO dimensions, the square form and 90° geometry ensure broad compatibility with standard external holders and boring bars when the correct pocket and fastening are used. The insert is supplied with a cylindrical hole and a 4.76 mm thickness, features that support secure clamping and repeatable positioning in the toolholder. Compatibility depends on form, clearance angle, tolerance class, fastening method, size and thickness; selecting a holder that matches those parameters avoids play and helps preserve tolerances in the workpiece. Clearances and fit are especially important when machining thin-walled or long components where stability is limited.

Cost-effective shop-floor performance and chip control in turning operations

The double-sided, reversible design reduces per-edge costs and simplifies inventory management, while the 1.2 mm corner radius provides a compromise between roughing strength and fine finishing capability. The insert’s double-sided chipbreaker concept supports improved chip control when the correct chipbreaker and feed are selected for the workpiece material and setup rigidity. For both external and internal turning tasks, this leads to fewer rejects, better surface quality and a lower total cost per part. The Tungaloy grade AH8015 is particularly suited where moderate to high temperatures occur, making it a practical first choice for general-purpose turning of heat-resistant alloys.

FAQ

What materials is this insert suitable for? The SNMG120412 AH8015 insert is formulated for machining heat-resistant alloys; the PVD-coated grade AH8015 balances wear resistance and edge stability for those materials.

Is the insert reversible and how does that affect costs? The insert is double-sided and reversible, which halves the number of inserts needed per cutting edge compared with single-sided designs and lowers the total tooling cost.

Which holders fit this ISO insert? Holders and boring bars that accept SNMG ISO geometry with matching pocket dimensions, fastening and tolerance class are suitable; correct clamping ensures repeatable positioning and machining accuracy.

How does the 1.2 mm corner radius influence surface finish? A 1.2 mm corner radius provides a blend of strength and surface quality, allowing stable cutting under moderate feeds while still achieving good finishes on turned components.

Can this insert be used for internal boring as well as external turning? Yes, the square 90° geometry and secure clamping via the cylindrical hole allow use in both external turning and internal operations when the appropriate boring bar and setup rigidity are provided.
