TNMG160412 AH8015 turning insert by Tungaloy

TNMG160412 AH8015 — a triangular ISO insert engineered for external and internal turning of heat-resistant alloys with reliable edge stability and versatile chip control

• PVD coating AH8015 for heat-resistant alloys
• ISO TNMG 160412 triangular insert, 16 mm
• 60° cutting angle with 0° clearance
• Double-sided chipbreaker and cylindrical hole

High-performance grade for heat-resistant alloys and long service intervals

The PVD-coated AH8015 grade combines wear resistance with a stable cutting edge to handle elevated temperatures and abrasive alloying elements. Designed as a cemented carbide insert, it provides a predictable balance between flank wear and edge chipping resistance, which translates into fewer unexpected tool changes and improved process uptime. Specified for turning applications, this geometry supports steady material removal rates and helps maintain machining schedules when processing demanding alloys.

Geometry and edge design that improve productivity and surface quality

A 60° principal cutting angle and a 0° clearance geometry ensure a secure cutting face engagement that reduces vibration in unstable setups. The 1.2 mm corner radius increases edge strength for interrupted cuts while still allowing controlled chip formation for plain turning. Together, these features contribute to consistent surface finish and reduced rework. The insert’s double-sided chipbreaker promotes repeatable chip segmentation, easing chip evacuation and lowering the risk of built-up edge on the cutting face.

ISO compatibility and system integration for straightforward toolroom use

Manufactured to ISO dimensions as a TNMG 160412 triangular insert with a 16 mm inscribed circle and 4.76 mm thickness, the component fits a wide range of standard external holders and boring bars. The cylindrical hole and standard fixing interface enable secure clamping and rapid index changes, supporting lean tooling procedures. Because compatibility depends on form, clearance angle, tolerance class, fixing method, size and thickness, this insert is best used within matched toolholder systems for predictable performance.

Application focus and selection advice for reliable machining results

Recommended primarily for turning (external and internal), the insert works well where heat resistance and a balance between wear and edge stability are required. Choose the chipbreaker and an appropriate cutting data set according to workpiece material and machine rigidity to achieve the best results. For less experienced teams, selecting a slightly reduced cut depth and moderate speeds when first implementing the grade helps confirm process windows. Technical consultation is available to align grade, geometry and cutting parameters with the production goal.

FAQ

What materials is this insert best suited for?
The TNMG160412 AH8015 Tungaloy turning insert is optimised for heat-resistant alloys and mixed alloy steels where a balance of wear resistance and edge stability is required.

Can the insert be used for both external and internal turning?
Yes. The TNMG160412 AH8015 insert is specified for external and internal turning when paired with the appropriate holder or boring bar.

How does the 1.2 mm radius influence cutting?
A 1.2 mm corner radius increases edge strength for interrupted cuts and supports improved surface finish while maintaining acceptable cutting forces.

Is the insert reversible or single-use?
The insert is double-sided, enabling index changes to a fresh cutting edge; secure clamping using the cylindrical hole and proper screws is essential.

Which holder features are necessary for compatibility?
Compatibility requires a holder that matches ISO form, clearance angle, tolerance class, fixing method, size and thickness; using standard ISO TNMG holders ensures correct fit and reliable clamping.
