DNMG150408 AH6225 Tungaloy turning insert — PVD-coated carbide, rhombic ISO insert for turning

The DNMG150408 AH6225 is an ISO-standard rhombic turning insert designed for external and internal turning of rostfreier Stahl, offering a sharp, stable cutting edge optimised for medium machining and variable conditions.

• ISO rhombic insert DNMG150408
• PVD-coated carbide AH6225 grade
• 0.8 mm corner radius for fine detail
• Double-sided chipbreaker, cylindrical hole

Maximum process reliability from the coating and grade

The PVD-coated carbide AH6225 delivers a balanced combination of sharpness and edge stability for routine to demanding turning tasks. The coating enhances wear resistance and thermal stability, which translates into longer intervals between indexings and fewer unscheduled tool changes. For machining rostfreier Stahl, this universal grade helps maintain a consistent surface finish while resisting edge deformation under fluctuating cutting conditions. The result is predictable component quality and reduced downtime, supporting efficient production workflows.

Seamless integration with ISO turning systems

Designed to conform to ISO geometry, the rhombic shape with a 55° cutting angle and a cylindrical hole ensures compatible clamping in standard DNMG toolholders. The insert thickness of 4.76 mm and the nominal plate size simplify selection of matching holders, underplates and clamping kits. Because holder compatibility depends on form, free angle, tolerance class, fastening and size, the ISO standardisation minimises setup uncertainty and supports repeatable clamping force — essential for stable cutting and reproducible results.

Improved chip control and operational stability

The double-sided chipbreaker geometry promotes stable chip formation across a range of feeds and depths of cut, reducing the risk of built-up edge and facilitating chip evacuation in both external and internal turning. The 0.8 mm corner radius provides a compromise between edge strength and finishing capability, enabling medium-accuracy work with improved tool life. For shops aiming to increase throughput without sacrificing finish, this insert supports steady material removal rates while keeping forces and vibrations in check.

Practical recommendations for selection and use

Select the DNMG150408 geometry together with the AH6225 grade when machining rostfreier Stahl under conditions where both edge sharpness and robustness are required. Match the insert to a rigid holder and appropriate clamping hardware to exploit the ISO-standard fit; choose feeds and speeds conservatively at first, then increase as process stability is confirmed. For changing workpiece materials or heavier cuts, consider a more robust grade or an alternate chipbreaker adapted to chip form and evacuation. For tailored advice on the best holder and process parameters, technical consultation is available.

FAQ

What materials is this insert suited for?
The DNMG150408 AH6225 insert is formulated as a universal grade for rostfreier Stahl and performs well in medium turning operations where a balance of sharpness and edge stability is required.

How is the insert mounted in standard toolholders?
Mounting follows ISO conventions for rhombic inserts: the DNMG150408 geometry, cylindrical hole and plate thickness align with matching DNMG toolholders and clamping kits to ensure secure, repeatable fixation.

What surface finish can be expected with the AH6225 grade?
With proper holder rigidity and optimised cutting data, the AH6225 grade supports consistent surface finishes in medium machining, aided by the 0.8 mm corner radius and the PVD coating that reduces edge wear.

How many indexing positions are available on the insert?
The insert is double-sided with a chipbreaker on both faces, providing multiple usable edges; indexing frequency depends on application severity and observed wear.

Which SKU should be ordered for this item?
Order using SKU 6947076-Tungaloy or manufacturer SKU TUN6947076 to ensure the correct DNMG150408 AH6225 Tungaloy insert is supplied.
