DNGG 110408 GT720 — ISO Turning Insert for Turning by Tungaloy

A DNGG110408-01 GT720 indexable insert engineered for finishing to light machining of steel, offering high surface quality and consistent dimensional accuracy in ISO-compatible turning systems

• Cermet grade GT720 for superior surface finish
• Rhombic geometry with 55° cutting angle
• Corner radius 0.8 mm for fine detail and tolerance control
• Cylindrical-hole design for secure clamping

Consistent finishing performance for precision turning

The GT720 grade is a cermet engineered for finishing to light machining of steel; it prioritises surface finish and dimensional accuracy while maintaining even wear across the cutting edge. In production environments where repeatability matters, a coated cermet substrate delivers lower built-up edge tendencies and stable cutting behaviour over long runs. The insert meets ISO plate standards, which means seating, size and thickness tolerances are predictable and compatible with standard external holders and boring bars, reducing setup time and the risk of misfit during tool changes.

Geometry tuned for fine surfaces and secure clamping

A rhombic plate with a 55° main cutting angle and 0° rake is optimised for close-tolerance external and internal turning where small depths of cut and clean edges are required. The 0.8 mm corner radius supports fine surface texture without sacrificing edge strength; smaller radii reduce cutting forces and help achieve target tolerances in finishing passes. The insert is supplied with a cylindrical hole, enabling secure fastening in a wide range of ISO-geometry holders and ensuring consistent seating and repeatable orientation. The listed spanbreaker style (01) enhances chip control in light cutting regimes, improving process stability.

System-level benefits and recommended applications

Used as part of a system—insert, compatible external holder or boring bar, support shim and appropriate clamping screw—this indexable plate contributes to predictable tool life and straightforward maintenance. The carbide substrate combined with the GT720 cermet coating supports stable wear for serial finishing of steel components, yielding fewer reworks and higher first-pass acceptance. Typical applications include precision external turning, internal profiling and fine-diameter operations where a combination of surface integrity and dimensional conformity is required. For selection between different grades or chipbreakers, consider workpiece material, machine rigidity and desired feed/speed strategy to match the insert to the process.

FAQ

What materials is this insert suitable for?
The DNGG110408-01 GT720 insert is specified for finishing to light machining of steel, with the GT720 cermet grade prioritising surface quality and consistent wear for such materials.

How does the rhombic 55° geometry affect cutting performance?
A 55° rhombic geometry provides a balanced approach between edge strength and access for fine turning tasks; it is well suited to external and internal finishing where a small contact area and accurate geometry control are required.

Does the insert fit standard ISO holders?
Yes, the insert follows ISO plate dimensions and is compatible with holders that match its form, clearance angle, tolerance class, fastening method, size and thickness; the cylindrical hole design supports secure clamping.

What advantages does the GT720 cermet offer over conventional carbide?
GT720 cermet is optimised for improved surface finish and dimensional control in finishing operations; it tends to produce even wear and reduced built-up edge compared with some uncoated carbide grades in light cutting scenarios.

Which system components are required for reliable assembly?
A complete system typically includes the indexable insert, a compatible external holder or boring bar, a support shim or clamp set and replacement fastening screws to ensure repeatable seating and safe operation.
