DNMG150408 GH330 Tungaloy ISO turning insert — rhombic 55°, double-sided, with cylindrical hole

The DNMG150408 GH330 Tungaloy is an ISO-standard rhombic turning insert designed for external and internal turning; compatibility with holders is determined by form, clearance angle, tolerance class, attachment, size and thickness.

• ISO rhombic insert, 55° cutting geometry
• GH330 grade with balanced wear resistance
• Double-sided insert with cylindrical hole for secure clamping
• 0° clearance angle for stable cutting

Consistent machining performance through a wear‑resistant grade

The GH330 grade combines wear resistance with sufficient toughness to maintain edge stability across interrupted and continuous cuts. Designed as a cemented carbide grade, the specification delivers a controlled compromise between life and reliability, which reduces the frequency of index changes and supports steady cycle times. Because the grade is optimised for general turning, the insert is particularly suitable where repeatable tool life and consistent surface quality are required.

Cost efficiency and secure clamping for productive turning

The double-sided geometry increases the number of usable edges per insert, improving cost-per-cut economics without compromising stability. The cylindrical hole and standard clamping interfaces ensure a secure seat in ISO-compatible holders; this stable fixation supports higher material removal rates where machine and workpiece stability allow. The rhombic 55° form gives a favourable approach for both finishing and medium-duty turning tasks while the 0° clearance angle helps maintain a repeatable cutting line in robust set-ups.

System-level compatibility and straightforward tool selection

The insert is intended for use as part of a turning system: ISO insert, matching external holder or boring bar, shim/clamping set and replacement fastening screws. Compatibility is determined by form, clearance angle, tolerance class, fastening method, size and thickness, so correct holder selection is essential. Select the chipbreaker and grade to match the workpiece material, cutting strategy and machine rigidity; this approach yields stable chip formation and consistent surface finish with minimal adjustment.

FAQ

What applications suit this insert best?
The DNMG150408 GH330 Tungaloy insert is intended for external and internal turning where a rhombic 55° geometry and balanced wear resistance are required; it performs well in general turning operations.

How does the GH330 grade influence tool life?
The GH330 grade provides a compromise of wear resistance and toughness, so the DNMG150408 GH330 Tungaloy insert gives consistent edge stability and predictable tool life across a range of turning tasks.

Is the insert compatible with standard ISO holders?
Yes — compatibility is governed by form, clearance angle, tolerance class, fastening method, size and thickness; the DNMG150408 GH330 Tungaloy insert is designed for ISO-standard holders.

What advantages does the cylindrical hole provide?
The cylindrical hole ensures secure clamping and correct seating in the holder, which improves repeatability and reduces the risk of insert movement during cutting when using the DNMG150408 GH330 Tungaloy insert.

How many cutting edges are available per insert?
The double-sided design provides multiple indexable edges, offering economical re‑indexing and reduced tooling cost per edge for the DNMG150408 GH330 Tungaloy insert.
