DNMG150412 T5115 ISO turning insert for turning by Tungaloy

DNMG150412 T5115 is an ISO-indexable turning insert designed for stable, economical machining of cast iron in ISO-standard holders.

• CVD-coated carbide for cast iron
• ISO rhombic 55° geometry
• 1.2 mm nose radius, 4.76 mm thickness
• Double-sided chipbreaker with cylindrical hole

Consistent chip control for productive cast-iron turning

The CVD-coated carbide grade T5115 delivers a balanced mix of wear resistance and cutting-edge stability, making it suitable for typical cast-iron turning tasks. The coating reduces flank wear and improves thermal resistance compared with uncoated grades, so the cutting edge retains its geometry over longer features and interrupted cuts. As a result, cycle times can be maintained with fewer tool changes, supporting more efficient shop-floor routines and predictable batch output.

Geometry and rigidity that support precise external and internal turning

The insert’s ISO rhombic 55° form and a 1.2 mm nose radius provide a stable engagement in both external and internal turning operations. The 55° approach angle balances axial and radial cutting forces, while the 0° clearance (relief) should be matched with the correct holder geometry to ensure reliable chip flow and minimal chatter. Compatibility with the clamping system is determined by form, clearance angle, tolerance class, fixing type, size and thickness; using the correct holder and shim ensures repeatable positioning and consistent surface finish.

Economical handling and quick indexing for continuous production

Being double-sided and fitted with a cylindrical hole, the insert permits easy indexing and secure clamping in standard DIN/ISO toolholders, reducing downtime during tool changes. The 4.76 mm plate thickness enhances bending resistance under heavier depths of cut, while the reversible nature of the insert improves tool utilisation per part. For operations where stability and cost-effectiveness are priorities, this grade and geometry combination helps keep tooling costs predictable and machine uptime high.

Practical selection hints for process optimisation

Select the double-sided chipbreaker style and the T5115 grade according to the component’s material and the machining strategy: roughing requires robust edge strength and generous chip control, while finishing benefits from the smaller nose radius and stable edge condition. The insert is part of a system comprising the insert, a matching external holder or boring bar, a shim/clamp set and replacement screws; ensuring correct combinations reduces assembly time and enhances process reliability. For complex workpieces, trial cuts with conservative feed rates reveal the optimal balance of surface finish and tool life.

FAQ

Is this insert suitable for cast iron machining?
The T5115 grade is a universal CVD-coated carbide developed for casting materials; the DNMG150412 insert is therefore suitable for cast-iron turning where balanced wear resistance and edge stability are required.

Can the insert be used in any DNMG holder?
Compatibility depends on holder form, clearance, tolerance class, fixing type, size and thickness; using a holder specified for DNMG 150412 geometry ensures correct clamping and positioning.

How many times can the insert be indexed?
The insert is double-sided, offering two usable cutting edges per index; actual lifetime per edge depends on cutting data, material, and machine stability.

What is the meaning of the 55° geometry for machining performance?
A 55° approach angle balances axial and radial loads, improving chip control and allowing stable cutting across a range of depths and feeds in turning operations.
