DNMG150412 T6215 indexable turning insert by Tungaloy — ISO 150412, CVD-coated grade for Turning

The DNMG150412 T6215 is an ISO rhombic indexable insert designed for external and internal turning of stainless steel under stable to lightly interrupted cutting conditions, offering a robust combination of wear resistance and dimensional stability.

• CVD-coated carbide grade T6215
• Designed for stainless steel turning
• Double-sided chipbreaker for stability
• ISO rhombic DNMG 15, 55° lead angle

Consistent cutting performance for stainless steel with low tool-change frequency

The CVD-coated carbide substrate in this insert provides a balanced combination of hardness and toughness that reduces flank wear when machining stainless steel, improving component consistency over longer tool lives. With a double-sided chipbreaker, the geometry controls chip shape to maintain stable cutting forces and reduce vibration, which directly translates into fewer interruptions and lower tooling costs per part. The insert’s corner radius of 1.2 mm supports moderate feed rates while preserving edge strength for finish passes, making it suitable for shops seeking predictable, repeatable results.

ISO compatibility and secure clamping for efficient tool set-up

Built to ISO dimensions, the rhombic form and cylindrical hole ensure compatibility with a wide range of external holders and boring bars when the correct form, relief angle and tolerance class are observed. The nominal thickness of 4.76 mm and 15 mm seat size match many standard DNMG pockets; the 0° relief angle and 55° lead angle define the insert’s cutting orientation and should be matched to the holder to achieve the specified cutting geometry. This standardisation reduces set-up time and simplifies tool inventory management for production and maintenance planners.

Durable coating and practical applications for improved productivity

Grade T6215 is a CVD-coated variant optimised for wear resistance under continuous contact with stainless steel, offering good edge stability in operations ranging from light finishing to medium turning cycles. The insert’s geometry supports both external and internal turning operations; the robust core and coating help maintain surface quality and dimensional control, particularly on longer runs. The result is higher uptime, fewer indexings and a measurable improvement in process reliability for everyday workshop use.

FAQ

What materials is this insert best suited for? The DNMG150412 T6215 insert from Tungaloy is optimised for machining stainless steel in stable to lightly interrupted conditions, providing good wear resistance and surface quality.

Which machine holders are compatible with this insert? Compatibility depends on the ISO form, relief angle, tolerance class, clamping method, size and thickness; DNMG-form holders and standard DNMG pockets with matching seat geometry suit this insert.

Is the insert suitable for finishing passes? Yes — with an appropriate feed and depth of cut, the 1.2 mm corner radius and the T6215 coating allow fine surface finishes on stainless steel during finishing operations.

How does the T6215 coating affect tool life? The CVD-coated T6215 grade improves wear resistance and edge retention on stainless steel, leading to extended tool life and fewer indexings in continuous production.
