DNMG 150412 T5115 Tungaloy turning insert — CVD-coated carbide for cast iron, rhombic DNMG 55°

The DNMG150412 T5115 is a rhombic, ISO-standard turning insert engineered for general external and internal turning of cast iron, featuring a double-sided chipbreaker and a cylindrical centre hole for secure clamping

• CVD-coated carbide grade T5115
• Optimised for cast iron machining
• Rhombic DNMG shape with 55° cutting angle
• Double-sided chipbreaker, cylindrical hole

Longer tool life through balanced coating and grade

The combination of a CVD-coated surface and a universal T5115 grade creates a dependable balance between wear resistance and cutting-edge stability. This balance reduces flank wear during extended cycles and supports consistent component tolerances in series production. For workshops seeking measurable gains in uptime, the coated cemented carbide offers a cost-effective route to longer tool life while maintaining predictable regrind intervals.

Stable chip control for reliable turning performance

A double-sided chipbreaker designed for cast iron yields controlled chip formation and evacuation, lowering the risk of built-up edge and surface damage. The rhombic DNMG geometry with a 55° cutting angle provides a versatile cutting orientation that suits both facing and light profiling. In practical terms, improved chip control means fewer interruptions, more consistent surface quality and higher overall process stability on lathes and bar-fed machines.

Compatibility and mounting guidance for shop floor use

Compatibility with a toolholder depends on form, relief angle, tolerance class, clamping style, size and thickness. The DNMG format with a cylindrical centre hole and a 0° relief angle is compatible with standard DNMG external holders and boring bars when the holder matches the ISO dimensions. The insert thickness of 4.76 mm and an insert size of 15 mm should be checked against the holder pocket and clamp to ensure correct seating and torqueing of the screw.

Practical advantages for cast iron applications

Designed as a universal solution for cast iron, this insert supports a wide range of turning tasks from roughing to finishing when feed and speed are adapted to the workpiece and machine rigidity. The corner radius of 1.2 mm contributes to edge strength and improved surface integrity on interrupted cuts. By choosing this CVD-coated grade, manufacturers benefit from reproducible cutting behaviour and simplified grade management across similar cast iron operations.

FAQ

What materials is this insert intended for?
The DNMG150412 T5115 insert is formulated as a universal grade for cast iron, providing balanced wear resistance and edge stability for typical cast iron turning applications.

How does the T5115 grade affect tool life?
The T5115 CVD-coated grade enhances wear resistance while maintaining edge robustness, which together extend effective cutting life under standard turning conditions.

Is the insert compatible with standard DNMG holders?
Compatibility depends on the holder matching ISO dimensions for form, relief angle, tolerance class, clamping and thickness; the DNMG150412 fits standard DNMG pockets when those criteria are met.

What is the corner radius and how does it influence cutting?
The insert has a 1.2 mm corner radius, which increases edge strength and improves surface finish stability, especially on interrupted cuts in cast iron.

Does the insert come with a chipbreaker suitable for finishing?
Yes, the insert features a double-sided chipbreaker designed to control chips across a range of feeds and depths, supporting both roughing and light finishing operations.
