DNMG150404 AH6235 Tungaloy turning insert for turning

The DNMG150404 AH6235 Tungaloy turning insert is an ISO‑standard rhombic insert designed for external and internal turning, optimised for stainless steels and applications prone to built-up edge or intermittent cuts.

• ISO DNMG geometry, rhombic 55° approach angle
• PVD-coated carbide grade AH6235
• Optimised for stainless steels and interrupted cuts
• Double-sided chipbreaker, cylindrical hole

Reliable performance for demanding turning operations

The DNMG‑style insert combines a 55° approach angle with a rhombic profile to deliver stable cutting in both external and internal turning. The PVD-coated carbide substrate provides a balance between toughness and wear resistance, which is particularly beneficial when machining stainless steels where work-hardening and edge breakdown are common. This geometry and coating pairing reduces the risk of premature edge failure and supports predictable tool life, meaning longer uninterrupted production runs and fewer insert changes.

Clear compatibility and secure clamping reduce setup time

ISO‑standardisation ensures straightforward selection of a matching holder: form, free angle, tolerance class, fixing method, size and thickness must be coordinated. The insert’s cylindrical hole and standard hole style facilitate positive clamping and repeatable seating in compatible toolholders, reducing the chance of vibration-induced wear. Specifying the correct holder and clamping set alongside the insert minimises deflection and improves surface finish, translating technical fit into measurable productivity gains.

Tailored grade and chip control for stainless steels

The AH6235 grade is a tougher PVD-coated carbide developed to manage the ductility and work-hardening tendencies of stainless steels. Its double-sided chipbreaker helps to fragment and evacuate chips even under interrupted cutting conditions, lowering the risk of built-up edge and improving dimensional stability. For operators less familiar with metallurgical terms: the coating increases surface hardness and thermal resistance, while the core carbide provides the mechanical strength to withstand shock and vibration.

Practical selection and application advice

When choosing this insert, match the 0° clearance and the 0.4 mm corner radius to the component’s tolerance and edge strength requirements; a larger radius gives more edge strength at the cost of slightly higher cutting forces, while a smaller radius favours finer finishes. The 4.76 mm thickness and 15 mm size are typical dimensions that affect rigidity—thicker and larger inserts provide higher stability for interrupted cuts. For efficient implementation, select a chipbreaker and grade aligned with material, feed rate and stability rather than relying solely on cutting speed charts.
