DNMG150416 T9215 — Rhombic indexable insert for turning, Tungaloy (CVD-coated carbide, 55°)

The DNMG150416 T9215 is an ISO-standard rhombic indexable insert engineered for external and internal turning, optimised for medium steel machining with a dual-sided chipbreaker and secure cylindrical hole fixing

• CVD-coated carbide for high wear resistance
• T9215 grade for medium steel machining
• Rhombic form with 55° cutting angle
• Double-sided chipbreaker, cylindrical hole

Boosted productivity through a wear‑resistant grade

The combination of a CVD-coated carbide substrate and the T9215 grade provides a balance between wear resistance and fracture toughness, which translates into longer tool life and fewer indexings during series production. For continuous to lightly interrupted turning of medium-strength steel, this configuration reduces unplanned downtime and keeps cycle times steady. The robust coating and substrate chemistry support stable edge behaviour under elevated cutting loads, so operators and process engineers can rely on reproducible results and reduced tooling costs per component.

Predictable system compatibility and simple selection

Being an ISO-standard insert, compatibility with the clamping system is defined by the insert’s form, clearance angle, tolerance class, fixing method, size and thickness. The rhombic geometry with a 55° main cutting angle provides a widely supported seating in standard DNMG pockets, while the cylindrical hole and defined thickness ensure secure clamping and repeatable positioning. When selecting a holder, match the insert's dimensional and tolerance data to the toolholder specifications to guarantee correct seating and cutting edge support for accurate turning.

Secure mounting and controllable chip formation

The insert’s double-sided chipbreaker allows consistent chip control on both indexable faces, helping to maintain surface quality and evacuation in long cuts. A corner radius of 1.6 mm adds strength at the cutting edge for stable roughing passes, while the 4.76 mm thickness contributes to bending resistance under higher radial depths of cut. Together, these attributes support higher material removal rates with manageable vibration and improved process reliability, especially when paired with a suitably rigid holder and machine setup.

Application focus and machining advice

Designed as a first choice for medium steel machining, this insert performs best under continuous and slightly interrupted cutting conditions where a balance between edge life and toughness is required. The insert’s properties encourage consistent surface finish and dimensional repeatability in production turning tasks. For process optimisation, pair the insert with a holder rated for the intended depth of cut and prefer cutting parameters that maintain chip compression within the chipbreaker’s effective range; this will exploit the grade’s wear resistance without compromising the edge’s fracture strength.

FAQ

Is this insert compatible with standard DNMG holders?
Compatibility is governed by the insert form, clearance angle, tolerance, fixing method and size; the DNMG150416 T9215 insert fits holders designed for DNMG 15×15 profiles and secures via a cylindrical hole, so a matching ISO DNMG pocket and clamp ensure correct seating.

Which materials is the T9215 grade suitable for?
The T9215 grade is formulated as a first choice for medium steel machining; the CVD-coated carbide substrate delivers high wear resistance while maintaining fracture toughness for productive turning of non‑hardened steel.

How does the 1.6 mm corner radius affect machining?
A 1.6 mm corner radius provides a stronger cutting edge for higher feed and roughing passes, improving tool life and part consistency, though it may increase cutting forces compared with smaller radii.

Can the insert handle interrupted cuts?
Yes — the balance of wear resistance and toughness in this grade supports continuous to slightly interrupted cuts; for heavy interruptions, choose a grade and geometry optimised for impact resistance.

What is the difference between the rhombic 55° form and other geometries?
The rhombic form with a 55° main cutting angle offers versatility for general turning operations and is commonly used for both external and internal turning, providing a compromise between accessibility and edge strength.
