DNMG 110412 AH6225 Tungaloy turning insert — PVD-coated carbide, 55° rhombic

The DNMG110412 AH6225 is an ISO turning insert engineered for external and internal machining of stainless steels, offering a balance of sharpness and edge stability for medium cutting conditions.

• ISO rhombic insert DNMG 55° geometry
• PVD-coated carbide grade AH6225
• Optimised for stainless steel turning
• Double-sided chipbreaker, indexable design

High-performance cutting for stainless steels

The DNMG110412 AH6225 insert combines a PVD coating with a carbide substrate to deliver a sharp, stable cutting edge that resists abrasive wear and maintains form under variable conditions. This results in predictable cutting forces and improved process stability when turning stainless steels, with a noticeable improvement in surface finish and repeatability. The 55° rhombic geometry helps to distribute cutting loads and supports efficient chip formation, which reduces the need for frequent tool changes and keeps cycle times low.

System compatibility and application flexibility

Designed as an ISO-norm insert, compatibility with a holder is defined by form, relief angle, tolerance class, fastening type, size and thickness. The rhombic shape and 0° clearance suit a wide range of external and internal turning operations; the double-sided design provides two usable edges per index for economical machining. Selection of the chipbreaker and grade should match workpiece material, machining type and setup rigidity to achieve consistent results in both stable and interrupted cutting conditions.

Durable coating and economical tool life

The AH6225 grade is a universal PVD-coated option optimised for a difficult-to-machine family such as stainless steels, offering good edge security at medium cutting parameters. The insert’s 1.2 mm corner radius and 4.76 mm thickness contribute to robust edge support, while the cylindrical hole ensures secure clamping and accurate repeatability. An indexable, double-sided format extends tool life per insert and reduces tooling costs, supporting continuous productivity and fewer machine stops for insert changes.

FAQ

What materials is this insert suitable for?
The DNMG110412 AH6225 insert from Tungaloy is primarily designed for stainless steels, offering a universal grade that balances edge sharpness and wear resistance for medium machining tasks.

Can the insert be used for both external and internal turning?
Yes, the rhombic DNMG geometry and indexable, double-sided layout make it suitable for both external and internal turning operations when paired with a compatible ISO holder.

What advantages does the PVD coating provide?
The PVD-coated carbide construction of the AH6225 grade enhances wear resistance and edge life, which leads to more consistent machining outcomes and longer tool life under variable conditions.

How does the corner radius affect the machining result?
The 1.2 mm corner radius provides stronger edge support for interrupted cuts and roughing operations, improving robustness and reducing the risk of chipping during demanding stainless-steel turning.

Which parameters determine compatibility with a toolholder?
Compatibility depends on insert form, relief angle, tolerance class, fastening method, size and thickness; matching these parameters ensures secure clamping and correct cutting geometry with the selected holder.
