DNMG150408 T6215 — ISO turning insert for stainless-steel turning (Tungaloy)

DNMG150408 T6215 is an ISO-form indexable insert designed for stable to slightly interrupted turning of stainless steel, offering a CVD-coated carbide grade optimised for wear resistance and steady tool life

• CVD-coated carbide grade T6215
• For stainless steel machining
• 0.8 mm corner radius for fine finishing
• 55° rhombic geometry, ISO DNMG form

Increased productivity for stainless‑steel turning

The CVD-coated carbide grade T6215 provides a balance of wear resistance and reliable cutting-edge stability, making it suitable for continuous and lightly interrupted turning of stainless steel. The coating reduces flank wear under typical turning conditions, which translates into longer tool life and fewer indexings per part — a direct contribution to higher process efficiency. For shops seeking reproducible results, the combination of a robust substrate and sophisticated coating helps maintain dimensional consistency and surface finish while lowering overall tooling costs.

Geometry that improves surface finish and chip behaviour

The 55° rhombic geometry with a 0.8 mm corner radius yields a positive cutting action that is particularly effective for finishing and medium-feed operations. The integrated double-sided chipbreaker ensures controlled fragmentation and evacuation of chips, reducing the risk of built-up edge and improving surface quality. For readers unfamiliar with chipformers: these are small, machined topographies on the insert face that direct and break the chip into shorter, safer segments — essential when machining ductile alloys like stainless steel where long chips can disrupt production.

Easy integration into standard toolholders and reduced downtime

Manufactured to ISO dimensions, the ISO DNMG150408 form fits a wide range of external holders and boring bars when the holder’s form, relief angle, tolerance class, fastening method, size and thickness are matched. The insert’s 4.76 mm thickness and with cylindrical hole design permit secure clamping and simple indexing; being double-sided, the insert effectively doubles the number of usable edges compared with single-sided types, minimising changeover frequency and maintaining spindle uptime. Compatibility notes in the technical literature explain how holder selection influences cutting parameters and achieve repeatable clamping accuracy.

Reliable choice backed by material and brand engineering

Tungaloy’s approach to grade development focuses on consistent performance and predictable wear progression, which supports stable production runs and simpler process planning. The insert’s CVD-coated surface and carbide substrate are engineered for repeatable results and straightforward edge preparation. For shops aiming to balance tool life and surface integrity, this insert offers a pragmatic option that pairs well with standard coolant strategies and proven machining parameters to enhance overall throughput and part quality.

FAQ

What steels is this insert suitable for?
The Tungaloy DNMG150408 T6215 insert is specified for machining stainless steel under stable to lightly interrupted conditions and performs best when paired with appropriate feeds and speeds.

How does the chipbreaker affect machining?
The double-sided chipbreaker on this indexable insert promotes shorter, controlled chips and improved evacuation, which helps maintain surface finish and reduces the risk of chip entanglement in turning operations.

Can the insert be used in standard DNMG holders?
Yes — the insert conforms to ISO DNMG dimensions; compatibility depends on matching holder form, relief angle, tolerance class, fastening, size and thickness to ensure secure clamping and correct cutting geometry.

How many cutting edges are available per insert?
Being double-sided, the insert offers multiple usable edges before replacement; this reduces downtime and improves cost-efficiency compared with single-sided alternatives.

Is the grade suitable for interrupted cuts?
The CVD-coated T6215 grade is intended for stable to slightly interrupted cutting; heavy interruptions may require a different grade or thicker geometry for optimal performance.
