DNMG150612 AH6225 indexable turning insert — rhombic, 55°, PVD-coated | Tungaloy

The DNMG150612 AH6225 is an ISO-format indexable turning insert engineered for external and internal turning operations, optimised for stainless steels and medium cutting conditions

• ISO rhombic insert, 55° cutting angle
• PVD-coated carbide grade AH6225
• Double-sided insert with cylindrical hole
• Suitable for external and internal turning

Consistent cutting performance with a wear-resistant grade

The PVD-coated AH6225 carbide grade combines a sharp, stable cutting edge with good wear resistance under varying conditions. As an ISO-format rhombic insert, the item provides repeatable performance in medium-duty turning of stainless steels, where a balance between edge strength and toughness is required. The coating reduces adhesion and built-up edge on challenging alloys, improving component quality while maintaining cutting efficiency. This results in fewer index changes and predictable tool life, supporting a steady production flow.

Geometry and system compatibility that reduce setup time

The rhombic DNMG geometry with a 55° approach ensures reliable engagement and accessible relief for many holder designs. The insert’s cylindrical hole and tolerance profile conform to ISO clamping conventions, so replacement and indexing are straightforward within compatible holders and boring bars. Being double-sided, the insert doubles available cutting edges per index, lowering per-edge cost and simplifying inventory management. Clear system compatibility reduces downtime and simplifies holder selection for routine turning tasks.

Measurable benefits in component quality and process stability

Applied correctly, this insert improves chip control and surface integrity during medium cuts, contributing to consistent surface finish and dimensional repeatability. The built-up edge resistance offered by the PVD-coated grade helps sustain feed and speed settings for longer cycles, while the stable edge reduces vibration risk in less rigid set-ups. For varied production runs, selecting a matching chipbreaker and ensuring stable clamping yields faster cycle times and fewer rework operations.

FAQ

Which materials is this insert suitable for?
The DNMG150612 AH6225 insert is designed primarily for stainless steels and performs well in medium machining operations where a balance of edge sharpness and robustness is required.

Is the insert single- or double-sided and how many cutting edges are available?
This is a double-sided indexable insert; the geometry allows two usable faces per side depending on indexing, effectively increasing the number of available cutting edges.

What is the corner radius and how does it affect the machined surface?
The corner radius is 1.2 mm; this radius supports good load distribution and contributes to a stable surface finish while allowing adequate strength at the cutting edge for medium cuts.

Does the DNMG150612 fit standard ISO holders?
Yes, the insert follows ISO turning insert dimensions and the cylindrical hole and tolerance class make it compatible with holders and boring bars that accept the DNMG form.

What benefits does the AH6225 PVD coating bring in production?
The PVD-coated AH6225 grade enhances wear resistance and reduces built-up edge on stainless steels, leading to more consistent tool life and improved process stability.
