DNMG150408 AH8005 ISO rhombic turning insert — PVD-coated carbide, double-sided chipbreaker (Tungaloy)

The DNMG150408 AH8005 is an ISO rhombic turning insert designed for stable external and internal turning of heat-resistant alloys and hard materials using standard ISO turning holders

• PVD-coated wear-resistant grade AH8005
• Suitable for heat-resistant alloys and hard materials
• Double-sided chipbreaker for stable cutting
• ISO rhombic 55° with 0.8 mm corner radius

Consistent performance for demanding turning operations

The combination of a PVD-coated carbide substrate and the AH8005 grade provides improved wear resistance at elevated temperatures, making the insert well suited to machining heat-resistant alloys and other challenging materials. The PVD layer reduces flank and crater wear, which directly contributes to longer tool life and more consistent component quality. In practical terms, this means fewer changeovers and more predictable cycle times when working under stable cutting conditions with robust clamping.

Designed for reliable clamping and simple system integration

Compatibility with a turning holder depends on form, free angle and tolerance class as well as fixing method, size and thickness. The insert features an ISO rhombic geometry with a 55° approach angle, 4.76 mm thickness and a cylindrical hole for secure mounting. These measurable attributes support straightforward selection of a matching external holder or boring bar. Descriptions such as form and thickness are crucial: they ensure the insert seats correctly, transmits cutting forces safely and maintains repeatable positioning across tool changes.

Optimised chip control and surface finish for efficient production

A double-sided chipbreaker integrated into the topography improves fragmentation and evacuation of chips in a broad range of feeds and depths of cut. Together with the 0.8 mm corner radius, this leads to balanced edge strength and surface quality during both finishing and medium-turning operations. The controlled chip flow reduces the risk of built-up edge on the insert and minimises secondary finishing work, delivering an efficient balance between productivity and component integrity.

FAQ

Which materials is the insert suitable for?
The insert is specified for heat-resistant alloys and other hard materials; the AH8005 grade and PVD-coated carbide substrate provide the required wear resistance for these applications.

What operations suit this insert?
The geometry and chipbreaker are optimised for external and internal turning where stable clamping and repeatable cutting conditions are available.

How does the chipbreaker help in production?
The double-sided chipbreaker improves chip fragmentation and evacuation, reducing the risk of entanglement and supporting steady surface finish and tool life.

How is the insert mounted in the holder?
Mounting depends on matching form, free angle, tolerance class, fixing method, size and thickness; the insert’s cylindrical hole and ISO dimensions facilitate correct seating in compatible holders.

What distinguishes the AH8005 grade?
The AH8005 grade is a wear-resistant PVD-coated carbide designed to withstand higher cutting temperatures and to provide consistent performance in demanding materials.
