CNMG120412 GH330 Tungaloy – ISO turning insert for external and internal turning, rhombic 80°

CNMG120412 GH330 Tungaloy is an ISO‑normed indexable insert for conventional and precision turning, designed to balance wear resistance and edge stability with broad material applicability

• ISO‑normed CNMG120412 form
• GH330 Tungaloy carbide grade
• 80° rhombic geometry, 1.2 mm nose radius
• Double‑sided chipbreaker with cylindrical hole

Reliable tool life through a wear‑resistant grade

The insert's GH330 Tungaloy grade is formulated for turning applications where a combination of wear resistance and edge toughness is required. In practice this means longer intervals between indexing and reduced frequency of insert changes, which supports consistent cycle times and improved productivity. The substrate of the insert is carbide, offering thermal stability during sustained cuts and reliable performance across interrupted and continuous turning. For production environments, the material choice translates into fewer process interruptions and a stable surface finish on the workpiece.

Precise fit and repeatable clamping for process stability

Built to the ISO CNMG120412 specification, the plate form and the cylindrical hole ensure compatibility with a wide range of external holders and boring bars when the holder matches by form, clearance angle and tolerance class. The 0° clearance angle and the 80° geometry deliver predictable cutting engagement, while the plate thickness of 4.76 mm and a defined 1.2 mm corner radius support rigidity at the cutting edge. This precision in geometry and fit reduces vibration and improves repeatability when the insert is clamped and indexed, making it suitable for both job shop and series production environments.

Adaptable chip control and application versatility

The double‑sided chipbreaker arrangement permits indexing to a fresh edge and helps control chip formation for a range of turning operations. Selecting the correct chipbreaker and the GH330 grade according to workpiece material and machining conditions enables efficient chip evacuation and consistent surface quality. The ISO series construction allows straightforward replacement and inventory management, while the rhombic CNMG shape is appropriate for both external profiling and light internal turning. Technical teams benefit from the balance of cutting performance and operational simplicity that this insert provides.
