DNMG 150416 T515 Turning insert by Tungaloy — 55° rhombic geometry, CVD-coated carbide

DNMG150416 T515 — a precision ISO‑standard turning insert designed for efficient machining of cast iron in general turning applications

• CVD-coated carbide grade T515 for cast iron
• ISO rhombic DNMG 55° geometry
• 1.6 mm corner radius, double-sided chipbreaker

Higher productivity for cast iron turning with consistent chip control

The CVD‑coated carbide of grade T515 is formulated for the economical machining of cast iron, combining wear resistance with predictable edge performance. Inserting the DNMG150416 into a properly matched holder provides productive turning through consistent chip formation and reduced edge flaking, especially under interrupted cuts. The double‑sided chipbreaker helps maintain short, controllable chips which simplifies swarf handling and reduces cycle time, translating into measurable process efficiency gains on batch and single‑piece production.

ISO compatibility and straightforward installation for reliable set‑up

As an ISO rhombic insert with 55° main cutting geometry, the DNMG150416 is compatible with a wide range of standard external holders and boring bars when matched by form, clearance angle, tolerance and fastening. The insert’s specifications — 0° relief angle, plate thickness 4.76 mm and cylindrical hole mounting — ensure secure clamping and repeatable positioning. Clear identification of the insert size and tolerance simplifies tool selection and reduces set‑up variability for production environments with multiple machines and operators.

Longer tool life and cost‑effective performance under variable conditions

The combination of a CVD coating and a robust carbide substrate results in balanced wear behaviour: resistance to abrasive wear while preserving edge stability. That balance yields longer tool life and fewer indexings, which lowers tooling costs per component. The 1.6 mm corner radius offers a compromise between strength and surface finish, permitting higher feeds for improved productivity without compromising dimensional control. Choosing the insert grade and chipbreaker according to workpiece stability and cutting speed optimises the overall cost‑benefit ratio in daily shopfloor use.

Suitable applications and selection guidance for practical use

Designed primarily for turning operations on cast iron, the insert is suitable for both external and internal turning when the cutting parameters and holder rigidity match the operation. For unstable set‑ups or heavy interruptions, selecting a lower cutting speed and ensuring solid toolholding will preserve the edge life of the grade T515. When replacing or reindexing, verify the holder’s seat and fastening parts for wear; correct clamping ensures the repeatable performance intended by the ISO‑standard geometry.

FAQ

What materials is this insert best suited for?
The DNMG150416 T515 insert is optimised for machining cast iron; the CVD‑coated carbide substrate and the chipbreaker geometry promote stable chip control and wear resistance in these materials.

Which geometry and mounting features does the insert have?
The insert features a 55° rhombic geometry with a 0° relief angle, a 1.6 mm corner radius, plate thickness 4.76 mm and a cylindrical hole for secure ISO‑standard mounting.

Is the insert single‑ or double‑sided and how does that affect life?
This DNMG insert is double‑sided, allowing indexing to a fresh cutting edge; combined with the T515 grade, this typically reduces tooling cost per part through extended overall edge life.

How should the holder be selected for best results?
Selection depends on form, clearance angle, tolerance, fastening and thickness; matching the holder to the insert’s ISO DNMG form and ensuring rigid clamping delivers the repeatable performance intended.

What benefit does the CVD coating provide in everyday use?
The CVD coating on the T515 grade improves abrasive wear resistance while maintaining edge strength, which is particularly advantageous when machining abrasive cast iron grades.
