DNMG150412 T9215 ISO turning insert (rhombic, 55°, CVD-coated) by Tungaloy

The DNMG150412 T9215 is an ISO-standard rhombic indexable insert designed for external and internal turning of medium steels, offering a balance of wear resistance and fracture toughness for continuous to lightly interrupted cuts.

• CVD-coated carbide grade T9215
• 55° rhombic geometry with 1.2 mm radius
• Double-sided with cylindrical hole and 4.76 mm thickness

Reliable compatibility for established ISO tool systems

The insert is supplied as an ISO turning insert, ensuring straightforward integration into standard holders; compatibility is determined by form, clearance angle, tolerance class, fixing method, size and thickness, which simplifies replacement planning and inventory management. As an ISO-conforming component, this insert supports predictable seating and clamping behaviour in established toolholders, reducing setup variability. The rhombic 55° geometry provides versatile cutting angles for general turning tasks, while the cylindrical hole supports secure fastening and repeatable positioning on the clamping system.

Optimised cutting performance for medium steels

Made from CVD-coated carbide in the T9215 grade, the insert combines high wear resistance with impact stability to maintain cutting-edge integrity under production loads. The coating improves resistance to abrasive wear and thermal softening during elevated cutting speeds, which directly contributes to longer effective tool life and fewer tool changes. For machining medium steel, this grade offers a pragmatic compromise between hardness and toughness—suitable for high-productivity environments where consistent surface finish and dimensional control are required.

Design choices that increase process reliability

A 1.2 mm corner radius provides a balance between strength and form accuracy: it increases edge robustness for roughing passes while still allowing for acceptable profile detail in finishing operations. The plate thickness of 4.76 mm improves stiffness in the tool assembly and reduces the risk of vibration on overhung setups. The double-sided chipbreaker delivers two usable cutting edges per side, supporting cost-effective indexing and predictable chip control. Together, these design elements reduce process pauses and enhance throughput in batch and continuous production.

Practical benefits and selection advice

Using this insert within a matched tool system helps achieve consistent component quality and lowers overall machining costs through extended service intervals. For applications with occasional interrupted cuts, the T9215 grade offers resistance to edge chipping while preserving an acceptable wear rate. When selecting a holder and operating parameters, match the insert form and 0° clearance specification with the clamping geometry and intended feeds to fully exploit the insert’s capability. For bespoke process parameters or material mixes, technical consultation is recommended to fine-tune cutting data and secure the best balance of productivity and tool life.

FAQ

What materials is this insert optimised for?
The DNMG150412 T9215 insert is optimised for medium steel machining; its CVD-coated T9215 grade balances wear resistance and toughness for productive turning operations.

How does the 1.2 mm corner radius affect machining?
A 1.2 mm radius strengthens the cutting edge for roughing and intermittent cuts while still permitting acceptable profile control during finishing passes.

Is the insert compatible with standard ISO holders?
Yes — as an ISO turning insert, compatibility depends on matching the form, clearance angle, tolerance class, fixing method, size and thickness to the chosen holder.

What benefits does the CVD coating provide?
The CVD coating improves resistance to abrasive wear and thermal effects at higher cutting speeds, resulting in longer tool life and more consistent surface quality.

How many edges are available before indexing?
The insert features a double-sided chipbreaker, providing multiple usable cutting edges to extend service life and reduce tool change frequency.
