DCMT 070208 GH730 – ISO turning insert for turning by Tungaloy (0.8 mm radius, 7° relief)

A DCMT070208 GH730 ISO rhombic indexable insert engineered for external and internal turning, featuring a single-sided chipbreaker and a cylindrical hole with 40°–60° countersink.

• ISO rhombic insert DCMT 070208 GH730
• 0.8 mm corner radius for precise profiling
• 7° relief angle, single-sided chipbreaker
• Cylindrical hole with 40°–60° countersink

Reliable edge life for steady production

The grade GH730, formulated by Tungaloy, combines carbide substrate performance with a cutting-edge balance of wear resistance and toughness, delivering predictable tool life under mixed turning conditions. For operations that alternate between light finishing and tougher profiling cuts, this balance reduces unexpected downtime and supports consistent batch quality. The result is a turning solution that lowers process variation and enables reliable cycle planning across shifts.

ISO geometry that simplifies holder matching

Built to ISO specifications, the rhombic shape and defined relief ensure compatibility with a wide range of external holders and boring bars; compatibility depends on form, 7° relief, tolerance class, fastening style, size and plate thickness rather than on informal descriptors. The standardised geometry facilitates quick tool changes and helps maintain concentricity and repeatability when paired with the correct clamping kit and replacement screws, reducing set-up time and improving overall machine uptime.

Controlled chip formation and versatile application range

The single-sided chipbreaker and the GH730 grade work together to provide predictable chip control for common turning tasks, especially where a mix of finishing and light to medium roughing is required. The 0.8 mm corner radius supports accurate profiling and interruptions-free edge engagement, while the insert’s construction allows selection of chipbreaker and grade matched to the component material and machining stability, helping to optimise surface quality and reduce rework.

Practical system considerations for efficient procurement

The insert is delivered as part of an ISO system concept: an ISO indexable insert, a matching external holder or boring bar, an underlay/clamping kit and spare screws form the complete toolset. Key specifications such as 2.38 mm plate thickness, size 07, rhombic form and a cylindrical hole with one-sided countersink (40°–60°) should be checked against the chosen holder for secure seating. For bespoke set-ups or questions about achieving the targeted surface finish, our technical advisers can recommend optimal holder geometry and cutting parameters.

FAQ

What types of turning is this insert intended for?
The DCMT070208 GH730 insert is designed for both external and internal turning operations, providing a balance between finishing and moderate roughing tasks.

Which features help control chip formation?
The single-sided chipbreaker combined with the GH730 grade promotes predictable chip control and consistent cutting behaviour during turning.

How is holder compatibility ensured?
Compatibility is determined by ISO geometry: form, relief angle (7°), tolerance class, fastening style, size (07) and plate thickness (2.38 mm); matching the holder to these parameters secures correct seating.

Can the insert be used for interrupted cuts?
The GH730 grade’s combination of toughness and wear resistance supports interrupted cutting, with the 0.8 mm corner radius aiding edge stability under variable load.

What information is needed when ordering replacement inserts?
Provide the ISO designation (DCMT070208), grade (GH730), manufacturer SKU (TUN6820984) and the intended holder type to ensure correct replacements and fast delivery.
