DNMG 150412 T5105 Turning Insert by Tungaloy

A DNMG150412 T5105 turning insert for ISO-standard external and internal turning, optimised for high-speed machining of cast iron under stable conditions.

• ISO rhombic insert DNMG150412
• CVD-coated cemented carbide T5105
• Double-sided chipbreaker for stable cuts
• Cylindrical hole and 0° clearance angle

High-speed cast-iron performance with controlled wear

The CVD-coated cemented carbide grade T5105 is developed for high-speed turning of cast iron where stability and predictable tool life are essential. The CVD-coated layer improves wear resistance by forming a hard, thermally stable barrier between the cutting edge and abrasive workpiece material, which reduces flank wear and extends effective machining time. For production environments that prioritise uptime and repeatable surface finish, this grade provides a measured balance between edge stability and toughness, making it a rational choice for operations seeking lower tooling costs per component.

Reliable clamping and ISO compatibility for straightforward integration

The insert follows ISO geometry for rhombic indexable plates, so compatibility with holders is determined by form, free angle, tolerance class, fastening, size and thickness. The plate features a cylindrical hole, a double-sided chipbreaker and a 0° clearance configuration with an included angle of 55°, creating a secure seating and predictable rake behaviour in a matched holder. These mechanical design choices reduce setup time and simplify index changes: once the correct external holder or boring bar and clamping set are selected, the plate can be rotated to present a fresh cutting edge without altering cutter-body geometry, supporting uninterrupted production routines.

Improved chip control and consistent surface quality

A 1.2 mm corner radius increases edge strength and helps maintain dimensional stability during interrupted cuts or when machining irregular cast-iron surfaces. The double-sided chipbreaker promotes reliable chip formation and evacuation at the speeds this grade is designed for, which reduces the risk of built-up edge and thermal damage to the cutting edge. With a plate thickness of 4.76 mm and a nominal size of 15 mm, this insert provides the rigidity required for stable external and internal turning while still allowing multiple indexes per plate, improving cost-efficiency. Specifying the correct chipbreaker and grade for the application leads to fewer tool changes and a higher first-pass yield.

FAQ

Which materials is this insert intended for?
The DNMG150412 T5105 Tungaloy insert (SKU 6852968-Tungaloy) is intended primarily for high-speed machining of cast iron under stable cutting conditions, with the grade optimised for abrasive, hard microstructures.

What does the 1.2 mm corner radius mean for component finish?
A corner radius of 1.2 mm on the DNMG150412 T5105 insert increases edge strength and improves dimensional stability, helping to deliver consistent surface quality while resisting chipping on interrupted cuts.

Is the plate indexable and how many usable edges does it offer?
Yes, the DNMG150412 plate is double-sided with a chipbreaker on each side; the design allows rotation to fresh cutting edges, which extends the usable life of each plate and reduces tooling change frequency.

Which holder types are compatible with this ISO plate?
Compatibility depends on matching holder form, free angle, tolerance class, fastening, size and thickness; the insert conforms to ISO DNMG geometry, so suitable ISO external holders or boring bars with the correct pocket and clamping system are required.

Can this insert be used for internal turning as well as external turning?
Yes, the DNMG150412 T5105 Tungaloy insert is suitable for both external and internal turning operations, provided the holder and process parameters are adapted to the specific machining situation.
