DNMG150612 AH6225 Tungaloy — Indexable Insert for Turning, PVD-coated Carbide

A DNMG150612 AH6225 indexable insert engineered for external and internal turning, optimised for stainless steel with a sharp yet stable cutting edge

• PVD-coated carbide for stainless steel
• 55° rhombic geometry for versatile turning
• Double-sided chipbreaker ensures stable chips
• ISO DNMG150612 — broad holder compatibility

Consistent cutting performance for stainless steels

The combination of a PVD-coated carbide grade and a geometry tailored to turning yields a reliable balance between edge sharpness and robustness. The AH6225 grade is developed as a universal option for stainless steel, offering good wear resistance under fluctuating cutting conditions and during medium-depth cuts. This means enhanced process stability and fewer interruptions for tool changes, translating into steady productivity for batch and single-piece production alike. The coating reduces built-up edge and improves heat resistance, supporting repeatable surface finish quality.

Geometry and mountability that simplify tooling decisions

The rhombic DNMG form with a 55° geometry delivers versatility across external and internal turning tasks. A 1.2 mm corner radius provides a compromise between strength and surface finish, while the 6.35 mm thickness and cylindrical hole align with ISO holder standards for straightforward mechanical clamping. Compatibility to a holder is determined by insert form, relief angle, tolerance class, fastening method, size and thickness; the ISO designation ensures the insert fits a wide range of commercially available turning holders, reducing the need for custom adapters and making tooling logistics simpler.

Better chip control, repeatability and system integration

Equipped with a double-sided chipbreaker, this indexable insert controls chip formation and evacuation, which reduces tool wear and stabilises machining forces. The insert’s two usable faces extend indexable life and lower tooling costs per edge. As part of a complete system — ISO insert, matching outer holder or boring bar, shim/clamping set and replacement screws — the component integrates easily into existing setups. Choosing the correct chipbreaker and grade according to workpiece material and machining stability optimises cycle time and component quality.

FAQ

Which materials is this insert best suited for?
The DNMG150612 AH6225 insert by Tungaloy is a universal grade developed for stainless steel and performs well when machining a wide range of stainless steels thanks to its PVD-coated carbide composition.

What advantages does the 55° geometry offer in turning operations?
A 55° rhombic geometry provides versatility for both external and internal turning, enabling effective approach angles for varied profiles while maintaining edge strength for medium-depth cuts.

How can I check if the insert matches my existing holder?
Compatibility depends on form, relief angle, tolerance class, fastening, size and thickness; the ISO DNMG designation of this insert simplifies matching to standard holders that accept DNMG-format inserts.

What benefit does the double-sided chipbreaker provide?
The double-sided chipbreaker improves chip control and evacuation, stabilising cutting forces and enhancing tool life; using both sides extends useful edge count and reduces tooling cost-per-part.

Which dimensions are essential to verify before ordering replacements?
Confirm geometry (DNMG150612), corner radius (1.2 mm), thickness (6.35 mm), insert size (15 mm), hole style (cylindrical hole) and relief angle (0°) to ensure correct fit and function.
