DNMG150612 T9225 turning insert — ISO turning insert by Tungaloy

The DNMG150612 T9225 is an ISO‑standard rhombic, double‑sided turning insert designed for medium to heavy steel turning operations, offering a combination of toughness and stable chip formation for interrupted or variable cutting conditions.

• CVD-coated carbide grade T9225
• 55° rhombic insert with 1.2 mm corner radius
• Cylindrical central hole, compatible with ISO holders
• Double-sided chipbreaker for medium to heavy steel

Longer edge life with consistent cutting performance

The CVD coating on the cemented carbide substrate provides a balanced combination of hardness and toughness, which translates into improved wear resistance without sacrificing edge security. For machining steel under medium to heavy cut depths, this composition reduces flank wear and preserves the cutting edge under fluctuating engagement. The T9225 grade has been specified as a robust universal grade that copes well with slightly interrupted cuts, helping to maintain cycle times and minimise unplanned tool changes.

Seamless integration into ISO tool systems

The rhombic 55° geometry and the cylindrical central hole ensure straightforward compatibility with standard ISO turning holders; compatibility is determined by form, clearance angle, tolerance class, fastening method, size and thickness. With a plate size of 15 mm and a thickness of 6.35 mm, the insert fits common external and internal turning toolholders. The 0° clearance angle and standard ISO designation make selection and replacement simple in established turning tool setups, reducing setup time and avoiding adapter rework.

Reliable chip control and adaptable cutting behaviour

The double-sided chipbreaker is engineered to produce stable, controllable chips in a range of cutting conditions, improving swarf evacuation and surface finish when stability is adequate. Selecting the appropriate chipbreaker and taking the insert’s 1.2 mm corner radius into account will influence both part geometry and surface quality: a larger radius supports higher feed rates and deeper cuts with improved tool support, while the chipformer design helps avoid long, stringy chips that impede productivity.

Cost-efficiency through durability and predictable performance

Using a robust universal grade reduces the need for frequent grade changes across mixed production runs. The combination of CVD-coated cemented carbide and a proven chipformer delivers longer intervals between indexings and predictable machining results, which lowers per-part tooling costs and minimises downtime. Backed by a recognised manufacturer, the insert supports reproducible processes and contributes to overall workshop efficiency.

FAQ

Which materials is the DNMG150612 T9225 suited for?
The DNMG150612 T9225 turning insert (Tungaloy, SKU 6780742‑Tungaloy) is optimised for medium to heavy steel machining; the CVD‑coated cemented carbide grade provides toughness for variable or mildly interrupted cuts.

Is the insert compatible with standard ISO turning holders?
Yes — the DNMG150612 follows ISO geometry conventions; compatibility depends on holder form, clearance angle, tolerance class, fastening method, size and thickness, aided by the cylindrical central hole and rhombic 55° shape.

How does the 1.2 mm corner radius affect results?
A 1.2 mm radius increases edge support and enables higher feeds and deeper cuts with improved surface finish; it also helps distribute cutting forces to reduce the risk of edge chipping in heavy cuts.

What benefits does the T9225 grade offer in production?
The T9225 grade delivers robust universal performance, stable chip formation and good wear resistance for a wide range of steels, reducing the frequency of grade swaps and supporting predictable cycle times.

How many usable cutting edges are available per insert?
The insert is double‑sided with an indexable geometry, providing multiple indexed cutting edges to extend service life before replacement.
