DNMG 150612 AH6235 turning insert (ISO) by Tungaloy — 55° rhombic, PVD-coated carbide

The DNMG150612 AH6235 is an ISO-standard indexable turning insert designed for external and internal turning operations, offering a robust grade for applications with increased breakout risk.

• PVD-coated carbide for rostfreier Stahl applications
• 55° rhombic geometry for versatile turning
• Double-sided chipbreaker for interrupted cuts
• Tough AH6235 grade for increased edge stability

Consistent machining of rostfreier Stahl and other challenging alloys

The PVD-coated carbide composition and the AH6235 grade are engineered for demanding environments, particularly when machining rostfreier Stahl and other work-hardened alloys. The tougher substrate of this grade reduces susceptibility to chipping under fluctuating cutting conditions, extending effective tool life. This results in fewer insert changes and a more predictable production rhythm, which contributes directly to lower process costs and improved line efficiency.

Secure seating and dimensional stability for reproducible results

Manufactured to ISO dimensions, the rhombic form and the cylindrical hole ensure exact positioning and secure clamping in compatibleholders. With a 6.35 mm thickness and a 1.2 mm radius, the geometry provides a stable cutting edge while the 55° approach angle supports a balance between cutting force and surface finish. Compatibility is determined by form, relief angle, tolerance class, fastening, size and thickness, so pairing the insert with the correct external holder and clamping set is essential for repeatable accuracy.

Improved chip control and resistance in interrupted cuts

The double-sided chipbreaker is optimised for interrupted cuts and applications with elevated breakout risk, guiding chips away from the workpiece and reducing heat concentration at the cutting edge. The PVD-coated surface enhances wear resistance and adhesion control, which is beneficial during medium to high cutting speeds. For shops aiming to maintain high throughput, this combination reduces downtime caused by edge failure and supports consistent part quality.

System considerations and selection guidance for productive turning

An efficient tooling system includes the ISO insert, a matched external holder or boring bar, a support/lock set and spare clamping screws. Selecting the correct chipbreaker and grade according to workpiece material and machining stability will yield the best results; for example, the AH6235 grade suits interrupted cutting in rostfreier Stahl, while different breakers or grades might be preferable for heavy roughing or finishing runs. Clear documentation of holder type and tolerance class simplifies reordering and reduces set-up time on repeat jobs.

FAQ

What workpiece materials is this insert best suited for?
The DNMG150612 AH6235 insert is optimised for rostfreier Stahl and other alloys that require a tougher grade to resist edge breakout; the PVD coating further improves wear resistance.

How does the 55° geometry affect cutting performance?
A 55° rhombic approach provides a balance between cutting forces and surface finish, making the insert versatile for both external and internal turning operations.

Is the insert reversible and how is it clamped?
This is a double-sided indexable insert with a cylindrical hole for secure clamping; the design supports two cutting edges per indexation to extend usable life.

Which components are needed to build a complete tool system?
A matching ISO external holder or boring bar, the appropriate support/klemmsatz and replacement clamping screws are required to assemble a functional system around the insert.

Can the AH6235 grade handle interrupted cuts?
Yes, the AH6235 grade is formulated to withstand interrupted cuts and applications with higher breakout risk, delivering stable edge behaviour under variable loads.
