• Rhombic DNMG shape, 55° cutting angle
• Corner radius 1.2 mm, with cylindrical hole
• Double-sided chipbreaker for stable chip control

Longer tool life through advanced coating and substrate

The combination of a CVD‑coated surface with a wear‑resistant carbide substrate increases tool life in medium‑steel turning. The chemical vapour deposition layer reduces flank and crater wear while the substrate maintains fracture toughness, permitting higher material removal rates without frequent index changes. This results in lower cost per part and fewer interruptions on the shopfloor, especially in continuous or slightly interrupted cuts where consistent edge integrity is essential. The coating also supports predictable tool‑change intervals, helping to plan production cycles more reliably.

Accurate fit and ISO compatibility reduce setup time

Compatibility with the toolholder is governed by geometric features such as shape, rake angle, tolerance class, fastening method, size and thickness. The DNMG form (ISO 150412) with a 55° cutting angle and 0° free angle ensures a precise fit in common external holders for turning. Correct matching of insert geometry to the clamping system minimises run‑out and positional error, which in turn reduces scrap rates and setup time. Clear adherence to the ISO specification streamlines tool inventory and simplifies holder selection for repeatable, efficient machining.

Stable chip control for improved surface finish and process security

The double‑sided chipbreaker design supports consistent chip formation and evacuation, lowering cutting forces and thermal load on the cutting edge. The presence of a cylindrical mounting hole enhances clamping stability in the seat, reducing vibration and contributing to a steadier cutting process. These characteristics combine to produce improved surface quality and reduced risk of built‑up edge, which is particularly valuable in unattended or high‑volume turning applications where process security and part consistency rank high.

Application range and machining guidance for best results

Designed as a first choice for medium steel machining, the grade balances wear resistance and resistance to chipping, making it suitable for both finishing and more aggressive roughing within its application window. The 1.2 mm corner radius offers a compromise between edge strength and achievable surface finish; increasing depth of cut or feed may call for a larger radius where available. With a plate thickness of 4.76 mm, the insert supports stable clamping and heat dissipation. For optimal performance, select the chipbreaker and grade according to workpiece stability and the cutting conditions—our technical team can advise on parameter windows for speed, feed and depth of cut.

FAQ

What materials is this insert suitable for? The DNMG150412 T9215 insert is primarily intended for medium steel machining; the T9215 grade combines wear resistance with fracture toughness for reliable performance in such materials.

How does the T9215 grade perform compared with other grades? Tungaloy’s T9215 grade (CVD‑coated carbide) offers a balanced combination of high wear resistance and chipping resilience, making it a productive choice where uninterrupted cutting and consistent tool life are required.

What effect does the 1.2 mm corner radius have on results? A 1.2 mm radius strengthens the cutting edge and increases resistance to fracture under heavier loads, while still enabling satisfactory surface finish in typical turning operations.

Is the insert indexable and how many usable edges are there? The rhombic DNMG form is double‑sided and indexable; the chipbreaker arrangement provides multiple usable cutting edges, improving utilisation and cost efficiency.

Which mounting characteristics should be checked for compatibility with a holder? Compatibility depends on form, free‑angle, tolerance class, fastening, size and thickness; the DNMG150412 dimensions, 0° rake and cylindrical hole must match the chosen holder’s seat and clamping system.
