DNMG150404 T9215 — Turning insert by Tungaloy, CVD-coated carbide, 55° rhomboid

The DNMG150404 T9215 is an ISO-standard, rhomboidal indexable insert for external and internal turning, optimised for medium-steel machining and continuous to light interrupted cuts

• CVD-coated carbide for wear resistance
• 55° rhomboid form, ISO DNMG150404
• 0.4 mm corner radius for precise finishes

Predictable productivity with a CVD-coated cutting grade

The combination of a CVD-coated hardmetal substrate and the T9215 grade offers a balance of wear resistance and fracture toughness aimed at mid-range steel machining. This provides a stable removal rate under continuous and light interrupted cutting conditions, allowing for reliable cycle times and reduced tool changes. The indexable design supports repeatable geometry, which translates into more consistent part tolerances and fewer unplanned stoppages.

Geometry engineered for dimensional accuracy and surface quality

The rhomboidal 55° form and the 0.4 mm corner radius are designed to produce controlled cutting engagement and good surface finishes in common turning operations. A plate thickness of 4.76 mm and an insert size of 15 mm ensure sufficient body stiffness for typical lathe holders; compatibility with a chosen holder depends on form, clearance angle, tolerance class, fastening and thickness. Accurate geometry reduces vibration and helps achieve repeatable part quality.

Secure clamping and effective chip control for process stability

A cylindrical hole and a double-sided chipbreaker ensure consistent seating and reliable chip formation during machining. The chip control geometry reduces the risk of entanglement and supports stable cutting forces, which improves both tool life and surface consistency. This combination is particularly advantageous in production environments where short set-up times and repeatable results are priorities.

Practical choice for production-oriented turning applications

As an ISO-standard insert in the DNMG family, the DNMG150404 T9215 suits shops seeking an economical, high-throughput solution for medium steel workpieces. Selection of the T9215 grade supports long tool life and good process reliability; matching the insert to the correct holder and cutting parameters yields measurable productivity gains and lower per-part tooling cost. For best results, pair the insert with holders specified for DNMG geometry and verified clamping systems.

FAQ

What materials is this insert best suited for?
The DNMG150404 T9215 is designed primarily for medium steel machining; the T9215 grade combines wear resistance and fracture toughness for productive turning of common steel alloys.

Will this insert fit standard DNMG holders?
Compatibility is determined by form, clearance angle, tolerance class, fastening, size and thickness; the DNMG150404 designation indicates the ISO geometry, but holder matching should be verified before use.

Which machining conditions are recommended for this grade?
The T9215 grade performs well in continuous to light interrupted cuts, offering stable wear behaviour and consistent tool life under typical production cutting parameters.

How does the chip control perform with this insert?
The double-sided chipbreaker promotes controlled chip formation and evacuation, contributing to stable cutting forces and improved surface finish during turning cycles.

Is the insert reversible or single-use per edge?
The DNMG150404 is double-sided with chipbreaker geometry on both cutting faces, allowing orientation changes to present a fresh cutting edge as permitted by the insert design.
