DNMG 150408 T515 — Turning insert DNMG for economical cast-iron machining (Tungaloy)

A DNMG150408 T515 indexable turning insert designed for ISO-standard holders, optimised for economical external and internal turning of cast iron components.

• ISO rhombic DNMG geometry 55° cutting angle
• CVD-coated carbide grade T515 for cast iron
• Double-sided insert with cylindrical hole
• 0.8 mm corner radius for stable finish

Productivity gains through targeted grade and coating

The combination of a CVD-coated carbide substrate and the T515 grade delivers a balance of tool life and cutting speed that favours cost-effective production. The coating reduces flank wear under interrupted cuts and maintains a stable cutting edge, while the carbide core retains toughness for moderate depths of cut. For workshop planning, this means fewer index changes and longer cycles between tool replacements, supporting continuous machining processes and predictable throughput.

Designed for secure mounting and versatile integration

Built to ISO dimensions, the rhombic DNMG shape and the cylindrical hole enable secure clamping in a broad range of external holders and boring bars. Compatibility is determined by holder form, relief angle, tolerance class, clamping method, size and thickness, so the insert integrates into standard tool systems without custom adapters. The 0° relief angle and the 55° cutting geometry provide a predictable tool orientation that supports repeatable set-up and simpler tool management across multiple machines.

Optimised for cast iron with a double-sided chipbreaker

The insert’s double-sided chipbreaker and application-oriented grade make it particularly suited to cast iron turning, where chip control and edge stability are critical. The chipformer manages swarf into controllable segments, reducing the risk of tangling during high-volume turning. This focused design choice results in safer operation and a cleaner work area, while the insert’s geometry contributes to consistent surface integrity on machined cast-iron parts.

Robust corner radius and finish consistency

A 0.8 mm corner radius offers a compromise between edge strength and surface finish, lending the cutting edge additional resilience against edge chipping while still achieving a fine finish on workpieces. This radius supports moderate feeds without sacrificing component quality, which is advantageous for batch production where dimensional consistency and repeatable surface characteristics are required. The double-sided format also aids economical use of the insert’s available cutting edges.

FAQ

Is the insert compatible with standard DNMG holders?
The DNMG150408 T515 is an ISO-standard rhombic insert; compatibility with DNMG holders depends on matching form, relief angle, tolerance class, clamping and the insert’s size and thickness.

Which materials is this insert best suited for?
This cutting grade and chipbreaker are optimised for cast iron machining; the T515 grade and CVD coating support economical and reliable performance on grey and nodular cast irons.

How does the double-sided design affect edge usage?
The double-sided construction provides additional usable cutting edges; the insert can be rotated or flipped to exploit remaining edges, improving cost efficiency per insert.

What role does the 0.8 mm corner radius play in machining?
A 0.8 mm corner radius increases edge robustness and contributes to a consistent surface finish, balancing strength and finish quality for medium-feed turning operations.

Is the DNMG150408 suitable for interrupted cuts or unstable set-ups?
The CVD-coated carbide and the chosen grade are intended to improve edge stability under varying conditions; for interrupted cuts, selecting appropriate depths of cut and feed rates together with the right holder rigidity is recommended.
