DCGT 070200 J740 Tungaloy indexable insert for turning (ISO rhombic 07, 7° clearance)

DCGT070200 J740 Tungaloy indexable insert designed for ISO-compliant external and internal turning with a rhombic geometry and single-sided chipbreaker

• ISO rhombic insert DCGT070200 J740
• 7° clearance angle for versatile turning
• Single-sided chipbreaker for consistent chips
• Cylindrical hole with 40°–60° countersink

Dependable cutting for stable production cycles

The indexable insert delivers a predictable balance of wear resistance and toughness thanks to the J740 carbide grade. The combination of this grade with a rhombic ISO geometry ensures stable cutting across a broad range of turning tasks. Use of a dedicated single-sided chipbreaker reduces chip entanglement and supports smooth evacuation, which in turn helps maintain cycle times and reduces unexpected downtime. Benefits are most apparent in serial production where repeatability and tool life contribute directly to cost efficiency.

Secure seating and precise geometry for repeatable accuracy

Compatibility with a holder depends on form, clearance angle, tolerance class, fixing method, size and thickness; these factors are all taken into account by the ISO system. The 7° clearance and 55° main angle of the insert provide predictable cutting engagement and help avoid rubbing on the flank, supporting superior surface finish and dimensional control. The cylindrical hole with a 40°–60° countersink gives reliable clamping and repeatable seat position, which reduces variability between indexings and supports consistent process quality.

Material technology and tool behaviour explained

Manufactured from high-quality carbide, the insert’s modern cutting-material composition is tuned for turning applications where a mix of abrasion resistance and edge stability is required. The J740 specification is selected to complement geometry by offering controlled wear progression and sufficient toughness to withstand intermittent loads. For users unfamiliar with carbide grades: the designation indicates a tailored microstructure and coating/finish that together influence tool life, edge retention and performance on different steels and non-ferrous materials.

Practical integration and selection guidance

When integrating this insert into a toolset, match the insert to the holder form and tolerance class specified by the machine tool supplier. The ISO designation DCGT070200 simplifies selection of compatible holders and clamping kits. For optimisation, choose the chipbreaker and grade that suit the workpiece material and the stability of the setup—short overhangs and rigid toolholding increase achievable cutting parameters. If needed, Metav Werkzeuge can advise on the correct mating holder or replacement screws to ensure correct assembly and maximum tool performance.

FAQ

What materials is this insert suitable for?
The Tungaloy DCGT070200 J740 insert is designed for turning and provides a broad material coverage thanks to the J740 carbide grade; it performs particularly well on standard steels and mixed production runs where wear resistance and edge stability are required.

How does the chipbreaker affect performance?
A single-sided chipbreaker on this insert results in consistent chip formation and controlled evacuation, which supports uninterrupted production and reduces the risk of chip interference in confined workspaces.

What must be checked for holder compatibility?
Compatibility depends on insert form, clearance angle, tolerance class, fixing method, size and thickness; ensure the holder matches the ISO DCGT geometry and uses the correct clamping screws and backing pad.

Can this insert be used for internal turning as well as external turning?
Yes, the insert’s rhombic shape and geometry allow for both external and internal turning applications where the holder and overhang permit stable cutting conditions.

How does the 7° clearance angle influence machining results?
The 7° clearance helps prevent flank contact and reduces rubbing, contributing to improved surface finish and reduced heat generation at the tool edge during turning operations.
