DNGG150408 GH110 Tungaloy indexable insert for turning (rhombic, 55°)

The DNGG150408 GH110 is an ISO‑compliant indexable carbide insert intended for external and internal turning operations, offering a rhombic form and a robust cutting edge.

• ISO-compliant rhombic geometry, 55° included angle
• GH110 grade for wear resistance and edge stability
• Double-sided chipbreaker for consistent chip control
• Central hole, cylindrical style for secure clamping

Precise ISO geometry for predictable setup and repeatability

The ISO-compliant rhombic shape with a 55° included angle provides a reliable cutting profile that simplifies holder selection and process planning. With a nominal insert size of 15 mm and a thickness of 4.76 mm, the geometry facilitates consistent engagement with the workpiece and predictable tool behaviour. Compatibility with standard toolholders is determined by form, relief angle, tolerance class, fastening and size; this standardisation reduces setup variance and supports repeatable production runs.

Long tool life and stable cutting through the GH110 grade

The chemical and microstructural optimisation of the GH110 grade delivers a balance of hardness and toughness that improves edge stability under typical turning loads. Manufactured in carbide, the grade is designed to resist abrasive wear while retaining sufficient fracture resistance for interrupted cuts. This results in extended usable life per edge and contributes to lower tool consumption over time, supporting cost‑effective machining where lifespan and consistent performance are priorities.

Reliable chip control and secure mounting for surface quality

A double-sided chipbreaker combined with a central cylindrical hole ensures controlled chip formation and positive clamping, reducing the risk of insert movement or vibration. The double-sided design doubles the number of available edges and aids heat dispersion, while the central hole style supports a secure mechanical engagement with many common ISO holders. As a result, finish quality is improved and the likelihood of chatter is diminished, producing surfaces that need less downstream finishing.

Versatile application range with a pragmatic system approach

Designed for turning, the insert is suitable for both external and internal turning when paired with the correct holder and chipbreaker variant; selecting the chipbreaker geometry and grade according to the workpiece material and machining conditions optimises productivity. The standard system setup comprises the indexable insert, a matching external holder or boring bar, a shim or clamping set and replacement screws, enabling straightforward maintenance and rapid edge changes on the shop floor. The compact rhombic form and 0° relief angle make the insert particularly useful where precise edge engagement and repeatable positioning are required.

FAQ

What materials is the insert suitable for? The GH110 grade insert is designed for a broad range of turning tasks; selection of the specific chipbreaker and cutting data should be matched to the workpiece material for best results.

How is the insert clamped in the holder? The insert features a central cylindrical hole that allows secure mechanical clamping in compatible ISO holders and boring bars, ensuring stable fixation during turning.

Can this insert be used for internal turning? Yes, the indexable geometry supports both external and internal turning when installed in an appropriate boring bar or internal holder with correct clearance.

How many cutting edges are available per insert? The double-sided configuration provides multiple usable edges; use of both sides doubles edge availability compared with single-sided designs, extending service intervals.

What does the GH110 designation mean for machining performance? The GH110 designation indicates a Tungaloy carbide grade optimised for a balance of wear resistance and toughness, improving edge life and stability in typical turning operations.
