TNMG160408 AH8015 Tungaloy Turning Insert — PVD-coated cemented carbide, 60°

A TNMG160408 AH8015 indexable turning insert for versatile external and internal turning of heat-resistant alloys, designed to fit ISO-standard holders and provide reliable cutting performance.

• PVD-coated carbide grade AH8015
• ISO TNMG triangular 60° insert
• 0.8 mm nose radius for precise contours
• Double-sided chipbreaker, with cylindrical hole

Consistent cutting for heat-resistant alloys

The PVD-coated AH8015 grade combines a fine cemented carbide substrate with a wear-resistant surface treatment to deliver balanced wear resistance and reliable edge stability during the machining of heat-resistant alloys. This composition reduces flank wear and maintains cutting geometry over longer intervals, which translates into fewer tool changes and more predictable cycle times. The result is dependable productivity when working on common high-temperature alloys in both roughing and light finishing operations.

Geometry and clamping ensure repeatable accuracy

The triangular ISO-standard form with a 60° cutting angle and a 0° clearance specification allows secure seating in compatible holders; compatibility is determined by form, clearance angle, tolerance class, fastening method, size and thickness. The insert’s 0.8 mm nose radius supports accurate contour generation without excessive tool overhang, while the cylindrical hole and robust plate thickness provide stable clamping and repeatable positioning for batch production. Clear geometry specifications simplify toolholder selection and reduce setup variation.

Efficient chip control and surface quality

Equipped with a double-sided chipbreaker, the insert manages chip formation in a range of cutting conditions and helps avoid tangling or surface damage, particularly when machining long or ductile swarf. The moderate nose radius promotes a good surface finish without sacrificing material removal rate, enabling a single insert to cover both medium-feed semi-finishing and finishing steps when parameters are optimised. Selecting the correct chipbreaker and adjusting feeds ensure consistent part quality and lower rework rates.

System approach for workshop reliability

This insert functions as part of a complete system: an ISO turning insert combined with a suitable external holder or boring bar, support pad or clamp set and spare fastening screws. Keeping matched components on hand reduces downtime and simplifies inventory management. The insert’s PVD surface and carbide core are tuned for general-purpose applications on heat-resistant alloys, offering a practical balance between tool life and edge toughness for everyday production environments.

FAQ

What materials is this insert designed for?
The TNMG160408 AH8015 Tungaloy turning insert is intended primarily for the general machining of heat-resistant alloys, offering a balance of wear resistance and edge stability for those materials.

How does the PVD coating affect performance?
The PVD-coated surface on the AH8015 grade improves wear resistance and reduces built-up edge under elevated temperatures, helping the TNMG160408 insert maintain cutting geometry for longer in demanding turning operations.

Which holder features must match the insert?
Compatibility requires matching the insert form, clearance angle, tolerance class, fastening method, size and thickness; using an ISO-compliant holder that accepts TNMG plates ensures secure clamping and repeatability.

Can this insert be used for both external and internal turning?
Yes, the triangular design and chipbreaker make the indexable insert suitable for both external and internal turning, provided the correct holder or boring bar and process parameters are selected.
