DNMG110408 AH6225 turning insert — PVD-coated carbide for stainless steel turning (Tungaloy)

The DNMG110408 AH6225 Tungaloy insert is an ISO rhombic indexable insert designed for external and internal turning where a sharp, stable edge and reliable chip control are required.

• PVD-coated carbide AH6225
• Optimised for stainless steel machining
• 55° rhombic DNMG110408 geometry
• Double-sided chipbreaker, 0.8 mm radius

Reliable cutting performance for stainless steels

The combination of a PVD-coated surface and the AH6225 carbide grade delivers a balance of edge sharpness and toughness that suits changing conditions in stainless steel turning. The coating reduces built-up edge and improves consistency at medium cutting depths, while the substrate material maintains a stable cutting edge under interrupted or variable feed conditions. This results in predictable component quality and fewer tool changes during batch production, supporting higher uptime and stable cycle times.

Precise ISO geometry for secure clamping and quick indexability

Built to ISO standards, the DNMG110408 geometry with a 55° rhombic shape and a cylindrical hole simplifies holder compatibility and repeatable seating. The standardised form, clearance angle of 0° and the defined tolerance class reduce setup variation and make replacement straightforward in modular tool systems. As a result, tool changeovers are faster and reproducibility between stations is improved, which benefits process reliability in job-shop and production environments.

Effective chip control and consistent surface finish

The double-sided chipbreaker is matched to mid-range turning and offers controlled chip formation when paired with the right feeds and speeds. The 0.8 mm corner radius balances edge strength and surface quality, helping to reduce chatter and deliver a consistent finish on ferritic and austenitic stainless steels. Combined, these features support a repeatable machining process with lower scrap rates and improved first-pass yield.

Practical application and integration into workflows

Suitable for both external and internal turning, the insert integrates easily into existing tooling systems. Selection of the appropriate chipbreaker and clamping arrangement should be based on component geometry and machine stability. Spare part stocking is simplified by the ISO reference and the manufacturer SKU, facilitating rapid replenishment and minimal production interruptions. For tailored cutting data and feed-speed recommendations, technical consultation is available to align the insert’s strengths with specific production goals.
