DNMG150616 AH8015 Tungaloy indexable insert for turning — PVD‑coated carbide, 55° rhombic geometry

DNMG150616 AH8015 Tungaloy indexable insert is an ISO‑compliant rhombic insert designed for external and internal turning of heat‑resistant alloys and general turning tasks

• PVD‑coated carbide AH8015
• Rhombic DNMG 55° geometry
• 1.6 mm corner radius
• Double‑sided, cylindrical hole

Reliable machining of heat‑resistant alloys with balanced tool life

The AH8015 grade is a PVD‑coated carbide designed as a first choice for the general machining of heat‑resistant alloys, offering a balanced compromise between wear resistance and edge stability. This balance reduces unexpected tool failures and contributes to a steadier process window. The coating improves high‑temperature performance and reduces flank wear, which in turn helps to maintain component tolerance and surface quality during extended operations.

Precise fit and ISO compatibility for predictable results

Built to the ISO series for rhombic inserts, the DNMG150616 geometry provides a 55° approach angle that suits both finishing and medium roughing when combined with appropriate cutting parameters. Compatibility with holders depends on the insert’s form, clearance angle (0°), tolerance class, fastening method, size and thickness; these factors determine seating, clamping reliability and cutting direction. The insert’s cylindrical hole and standard dimensions (15 mm size, 6.35 mm thickness) ensure a predictable mechanical interface with ISO‑standard external holders and boring bars.

Operational benefits: economy, flexibility and reduced downtime

As a double‑sided insert with a 1.6 mm corner radius, this plate doubles tool life per index and supports quick index changes, lowering per‑part tooling cost and machine downtime. The rhombic shape enables multiple cutting positions and good access in shoulder and profile turning. Use of a suitable double‑sided chipbreaker helps control chip form across a range of cutting depths, while the PVD surface treatment promotes consistent edge integrity, so fewer interruptions for edge dressing are required and productivity is improved.

Guidance on selecting grade and chipbreaker for specific tasks

Select the AH8015 grade when machining alloys that demand both heat resistance and stable cutting edges; pair the insert with an appropriate chipbreaker type according to workpiece material, mode of machining and machine rigidity. For unstable setups or heavy interrupted cuts, favour more robust edge preparations and conservative cutting data; for stable finishing operations, exploit the insert’s coating and geometry to increase cutting speed and improve surface finish. The series can be combined with matched holders, clamp sets and replacement screws as part of a complete tooling system.

FAQ

What materials suit this insert best?
The DNMG150616 AH8015 Tungaloy indexable insert is optimised for heat‑resistant alloys and general turning of steels and alloys; its PVD coating and carbide substrate suit operations where a balance of wear resistance and edge stability is needed.

Can the insert be used on internal turning operations?
Yes, the rhombic DNMG geometry and 55° approach angle make the plate suitable for both external and internal turning when mounted in a compatible ISO holder.

How does the AH8015 grade compare for productivity and tool life?
AH8015 provides a compromise between wear resistance and edge stability, delivering reliable tool life in a wide range of applications and contributing to steady productivity without excessive compromise on cutting speed.

Is the insert reversible and how many cutting edges are available?
The insert is double‑sided and indexable; each plate provides multiple cutting edges to reduce changeover frequency and lower tooling cost per edge.

What should be considered when pairing with a holder?
Ensure the holder matches the insert’s form, clearance angle (0°), tolerance class, fastening method, size and thickness for correct seating and clamping; the cylindrical hole and standard dimensions aid compatibility.
