DNMG110412 AH6225 indexable turning insert – ISO rhombic, PVD-coated carbide by Tungaloy

The DNMG110412 AH6225 is an ISO-standard indexable insert for external and internal turning, engineered for stable cutting in variable conditions and optimised for stainless steels.

• PVD-coated carbide for long tool life
• Sharp, stable cutting edge
• ISO-standard rhombic geometry
• Cylindrical hole with double-sided chipbreaker

Greater process reliability through a robust cutting grade

The AH6225 grade combines a PVD-coated carbide substrate with a cutting geometry designed for reliable metal removal when turning. This configuration promotes stable chip formation and extends tool life under medium cutting parameters, resulting in fewer insert changes and less downtime. The PVD layer increases wear resistance while maintaining an edge that resists chipping during interrupted cuts, which supports predictable cycle times and improved throughput for everyday production tasks.

Easy integration into ISO-compatible tool systems

The rhombic plate format and standardised dimensions ensure ISO compatibility with a wide range of external tool holders and boring bars. The DNMG110412 form factor, including the cylindrical centre hole, fastens securely to common clamping systems and benefits from a consistent tolerance class for repeatable seating. This predictability reduces setup time and facilitates quick insert indexation, enabling efficient changeovers and steady component quality across batches.

Optimised for stainless steels and variable conditions

AH6225 is a universal grade tailored to stainless steels, delivering a combination of a sharp, stable cutting edge and a double-sided chipbreaking geometry. The 55° plate angle and 1.2 mm corner radius produce a balance between surface finish and edge strength, helping to avoid built-up edge formation on adhesive materials. The double-sided chipbreaker assists in controlled chip segmentation during both continuous and interrupted cuts, reducing the risk of workpiece damage and easing chip evacuation.

FAQ

What material is the AH6225 grade aimed at?
The AH6225 grade is formulated for machining stainless steels, offering a balance of wear resistance and edge stability for medium turning operations.

Can the DNMG110412 fit standard ISO holders?
Yes — the DNMG110412 is an ISO-standard rhombic insert and is compatible with common external holders and boring bars that accept DNMG geometry.

How does the PVD coating benefit tool life?
The PVD-coated carbide surface on the DNMG110412 AH6225 reduces abrasive wear and improves thermal resistance, resulting in longer in-service life and fewer insert changes.

Is this insert suitable for interrupted cuts?
The combination of a stable cutting edge and the double-sided chipbreaker on the DNMG110412 AH6225 supports interrupted cutting conditions by resisting chipping and promoting controlled chip formation.

What are the key dimensions to check when selecting a holder?
Verify the insert size (11 mm), plate thickness (4.76 mm), corner radius (1.2 mm) and the plate angle (55°) to ensure correct seating and clamping in the chosen holder.
