DNMG 150402 T9215 turning indexable insert by Tungaloy — CVD-coated carbide, rhombic 55° geometry

DNMG150402 T9215 is an ISO-standard rhombic, double-sided turning insert designed for medium-steel machining, optimised for continuous to slightly interrupted cuts and secure clamping in ISO-compatible holders

• ISO-compatible DNMG150402 geometry
• CVD-coated carbide grade T9215
• 0.2 mm corner radius for fine finishing
• Double-sided chipbreaker with cylindrical hole

High productivity from the T9215 coating and carbide substrate

The combination of a CVD-coated carbide substrate and the T9215 grade is engineered to provide a balanced mix of wear resistance and fracture toughness for medium-steel applications. This results in longer edge life under stable cutting conditions and fewer tool changes per shift, which improves overall productivity. The coating reduces adhesion and abrasion at the cutting edge, while the carbide core sustains cutting forces, making the system particularly well suited to continuous turning and light interruptions without sacrificing component quality.

Geometry and clamping that support consistent surface quality

The insert’s rhombic 55° geometry and 0° clearance angle produce predictable cutting forces and a favourable approach for both external and internal turning. The 0.2 mm corner radius helps achieve a controlled surface finish while still allowing for modest depth of cut. The plate thickness of 4.76 mm and the cylindrical through-hole provide robust, repeatable clamping in compatible ISO holders; compatibility is determined by matching form, free angle, tolerance class, fixing method, size and thickness to the chosen holder. These design choices together reduce vibration and help maintain dimensional accuracy across production runs.

System benefits and recommended applications for machining shops

As part of an ISO insert system, the plate works with a matching external holder or boring bar, plus a suitable clamp set and retaining screw for safe fixation. The double-sided chipbreaker supports reliable chip formation and evacuation, lowering the risk of built-up edge and improving tool life per index. Typical uses include general turning tasks on medium-carbon steels where a cost-effective, high-productivity solution is required. For specific material mixes or more heavily interrupted cuts, select the correct chipbreaker and grade combination to match stability and cutting conditions; Metav Werkzeuge consultants can advise on holder pairing and process parameters.

FAQ

What materials is this insert best suited for? The DNMG150402 T9215 insert is optimised for medium-steel machining; the T9215 grade combines wear resistance and toughness for productive turning.

Can the insert handle interrupted cuts? The T9215 grade and double-sided chipbreaker tolerate light to slight interruptions; for heavily interrupted applications, a more robust setup or alternate grade is recommended.

How many cutting edges are available per insert? The rhombic, double-sided geometry provides two usable cutting edges per index, doubling effective life before replacement.

What should be checked when selecting a compatible holder? Compatibility depends on matching the insert form, clearance angle, tolerance class, fixing method, size and thickness to the holder; ensure the holder accepts DNMG inserts with the specified through-hole style.

Is this insert suitable for internal turning and boring operations? Yes; the insert’s geometry and thickness make it appropriate for both external and internal turning when mounted in the correct ISO-compatible boring bar or holder.
