DNMG 150404 T515 DNMG Turning Insert — CVD-coated carbide for cast iron — Tungaloy

The DNMG150404 T515 is a rhombic ISO turning insert optimised for economical machining of cast iron, featuring a double-sided chipbreaker and a cylindrical hole for secure clamping.

• Rhombic ISO geometry with 55° lead angle
• CVD-coated carbide for cast iron machining
• Double-sided chipbreaker for reliable chip control
• Cylindrical-hole design and 0.4 mm corner radius

Economical, high-speed machining of cast iron with predictable tool life

The CVD-coated carbide grade T515 is engineered for productive machining of cast iron, offering a balance between wear resistance and cost-efficiency. A chemical vapour deposition layer increases thermal stability and reduces flank wear during continuous cutting, which enables higher cutting speeds and longer intervals between indexings. In production contexts where cycle time and repeatability matter, this coating supports a stable process window and reduces overall tooling consumption. The result is more consistent component quality with lower running costs when processing grey and nodular cast irons.

Consistent chip control and secure clamping reduce downtime

The double-sided chipbreaker integrated into the insert geometry aids controlled chip formation across a range of depths of cut and feed rates, improving evacuation in both continuous and semi-interrupted cuts. The rhombic shape combined with a 0.4 mm corner radius offers a compromise between edge strength and surface finish, making the insert suitable for finishing and medium-duty turning. The cylindrical hole and ISO mounting form ensure positive location in the toolholder; when used with the correct shim and screw, the assembly delivers repeatable clamping force and minimal vibration, which together reduce edge chipping and unplanned tool changes.

Seamless integration into ISO turning systems for reliable production

Designed as part of the ISO turning inserts family, the DNMG format provides straightforward compatibility with standard holders when dimensions and tolerance classes match. Key dimensions — 15 mm size, 4.76 mm thickness, 55° lead angle and 0° clearance angle — determine suitability for a given toolholder. System components typically include the insert, a matching external holder or boring bar, an underlay or clamp set, and replacement screws. Selection of the correct chipbreaker variant and grade should be based on component stability, the presence of interrupted cuts and the desired cutting speed; the grade T515 is recommended for economical, high-throughput cast iron applications.

FAQ

Which materials is this insert best suited for?
The T515 grade is optimised for machining cast iron; the DNMG150404 geometry offers good performance on grey and nodular cast irons in both continuous and semi-interrupted cuts.

What are the key geometric features to note?
The insert is rhombic with a 55° lead angle, 0.4 mm corner radius, 15 mm size and 4.76 mm thickness, and it comes with a cylindrical hole for secure clamping.

How does the chipbreaker influence performance?
The double-sided chipbreaker provides consistent chip control across feeds and depths of cut, improving evacuation and helping to maintain surface quality while reducing the risk of chip entanglement.

How is holder compatibility ensured?
Compatibility for an ISO insert depends on matching the holder by form, clearance angle, tolerance class, attachment method, size and thickness; select holders that correspond to the DNMG form and tolerance for correct seating.
