DNMG110412 T9215 DNMG 110412 turning insert by Tungaloy — CVD-coated carbide, 55° rhombic

The DNMG110412 T9215 is an ISO rhombic turning insert engineered for reliable external and internal turning, optimised for medium steel machining.

• CVD-coated carbide for high wear resistance
• Designed for medium steel machining
• 55° rhombic geometry with 1.2 mm radius
• Double-sided insert; cylindrical hole for secure fit

Proven performance for productive turning

The CVD-coated carbide grade T9215 provides a balance of wear resistance and fracture toughness that favours uninterrupted production runs. As an ISO rhombic indexable insert, this turning solution reduces tool changes compared with edge-style tooling while delivering repeatable results. The combination of coating and substrate allows for higher cutting speeds under stable conditions, which translates directly into improved cycle times and lower cost per part. The specification emphasises predictable wear behaviour and a robust cutting edge for mid-range steel alloys.

Secure fit and geometry that supports machining stability

The 55° rhombic geometry and 1.2 mm corner radius are selected to provide a compromise between edge strength and surface finish. The insert is double-sided, featuring a cylindrical hole for positive location in compatible holders; compatibility is determined by form, clearance angle, tolerance class, clamping method, size and thickness. With a 0° clearance angle and a standard ISO designation, the insert suits common external and internal turning set-ups where stable clamping and repeatability are priorities. This geometry helps to control cutting forces and vibration, supporting a more consistent surface quality.

Coating and substrate benefits explained

The insert’s CVD coating forms a hard, wear-resistant layer that improves abrasion resistance and thermal stability at the cutting edge. Beneath the coating, the carbide substrate absorbs shock and resists chipping, enhancing service life during continuous and lightly interrupted cuts. For medium steel applications, this pairing ensures effective chip formation and manageable heat distribution, reducing the need for frequent index changes and maintaining component tolerances across batches. The result is reliable tool life and consistent dimensional accuracy.

Application advice for efficient integration

Designed for turning operations, this insert performs best when matched to a suitable external holder or boring bar and supported by a stable machine set-up. Choosing the appropriate chipbreaker and grade to match workpiece material and cutting strategy will further optimise productivity. Where process security and repeatability matter, the insert’s ISO conformity simplifies tool selection and inventory management. For production-focused environments, the insert contributes to fewer interruptions, predictable maintenance intervals and a smoother overall workflow.

FAQ

What materials is this insert best suited for?
The DNMG110412 T9215 insert is specified for medium steel machining; the T9215 CVD-coated carbide grade combines wear resistance and toughness for this material class.

How does the T9215 coating affect tool life?
The CVD-coated carbide surface of the Tungaloy DNMG110412 reduces abrasive wear and helps maintain edge integrity, extending effective tool life during continuous and lightly interrupted cuts.

Is this insert reversible or indexable on both sides?
Yes, the insert is double-sided, allowing indexing to a fresh cutting edge and offering a cost-effective use of available cutting edges.

Which geometry and corner radius does the insert have?
This ISO rhombic insert uses a 55° geometry with a 1.2 mm corner radius, balancing edge strength and achievable surface finish for turning operations.

What should be considered when selecting a holder for this insert?
Holder compatibility depends on insert form, clearance angle, tolerance class, clamping method, size and thickness; ensure the external holder or boring bar matches the ISO designation DNMG110412 to secure correct fit and repeatability.
