DNMG150412 AH6225 ISO 150412 rhombic indexable turning insert for turning – Tungaloy

The DNMG150412 AH6225 is an ISO rhombic, double-sided indexable insert engineered for dependable external and internal turning of rostfreier Stahl and similar materials

• ISO rhombic DNMG 55° geometry
• PVD-coated AH6225 grade for rostfreier Stahl
• 1.2 mm corner radius for versatile profiles
• Double-sided insert with cylindrical hole

Predictable cutting performance for rostfreier Stahl machining

The combination of a PVD-coated surface and a high-quality carbide substrate delivers a balance of wear resistance and edge sharpness that is particularly suited to rostfreier Stahl. The AH6225 grade is designed to maintain a stable cutting edge under changing cutting conditions, reducing the frequency of insert changes and supporting predictable cycle times. PVD coating provides a thin, hard layer that improves resistance to adhesive wear and heat, while the carbide core preserves toughness. In practical terms, this means fewer interruptions for tool changes and a more consistent surface finish on turned components.

Faster changeovers and reliable holder compatibility

Standardised ISO geometry simplifies toolroom logistics: the DNMG shape and the ISO 150412 designation match common external holders and boring bars, so replacement is straightforward when the insert requires indexing. The rhombic 55° lead angle offers a compromise between strength and access, while the double-sided design effectively doubles the usable cutting edges compared with single-sided inserts. The cylindrical centre hole and defined thickness ensure secure clamping and repeatable positioning, which in turn helps to maintain dimensional accuracy and reduce set-up time during shift changes or batch swaps.

Practical guidance to extend tool life and improve output

Selecting the correct chipbreaker and machining parameters is essential: choose the chipbreaker style that matches the workpiece ductility and the stiffness of the set-up. The medium-duty profile of this grade is intended for moderate cutting depths and intermittent conditions; optimised feeds and speeds for rostfreier Stahl will reduce built-up edge and improve edge life. The modest corner radius 1.2 mm supports a favourable balance between edge strength and detail reproduction on turned contours. For shops aiming to increase throughput without sacrificing surface quality, the combination of AH6225 and an appropriate chip control geometry is a pragmatic, cost-effective choice.

FAQ

What materials is this insert suited for?
The AH6225 grade is formulated for rostfreier Stahl and similar alloys; the DNMG150412 geometry supports a range of turning tasks on these materials.

What does the 1.2 mm corner radius mean in practice?
A 1.2 mm corner radius provides increased edge strength for medium-duty turning while still allowing the reproduction of profile details on external and internal contours.

Will this insert fit existing ISO holders?
The ISO DNMG150412 designation and standard plate dimensions mean the insert is compatible with holders designed for DNMG plates, subject to matching form, thickness and clamping method.

What chip control does the insert provide?
The plate is supplied with a double-sided chipbreaker; selecting the appropriate chipbreaker orientation and feed rates helps maintain stable chips and reduces rework.

How can tool life be optimised with this grade?
Optimising cutting speed, feed and depth of cut for rostfreier Stahl, ensuring a rigid set-up and using the correct chipbreaker will extend edge life and enhance process stability.
