TNMG 160408 GH330 — ISO turning insert (60° triangle, 0° rake) by Tungaloy

A TNMG 160408 GH330 ISO turning insert designed for general external and internal turning, compatible with ISO toolholders where form, clearance angle and size match

• GH330 grade: wear resistance and edge stability
• 60° triangular insert, 0° rake angle
• Double-sided with cylindrical hole for secure clamp
• Carbide construction, 0.8 mm corner radius

Stable machining through geometry and material choices

The insert combines a 60° triangular shape with a precisely defined 0° rake, delivering a balanced cutting action for a wide range of turning tasks. Manufactured from cemented carbide, the component offers a compromise between hardness and toughness that supports consistent chip formation and predictable wear. The ISO-series design ensures that the insert fits standard indexable holders when form, clearance angle, tolerance class, fastening method, size and thickness correspond, so workshop planners can rely on established tooling systems for integration and repeatable set-up.

Improved process reliability with chip control and clamping

Equipped with a double-sided chipbreaker and a cylindrical hole for positive clamping, the insert helps maintain secure fixation and effective chip evacuation even under interrupted cuts. The 0.8 mm corner radius and a plate thickness of 4.76 mm add rigidity at the cutting edge, reducing vibration and improving surface finish. These measurable characteristics translate into fewer tool changes and a steadier cycle time in serial production; selecting the correct chipbreaker and grade for the workpiece material further enhances tool life and component quality.

Practical selection and application guidance for workshop use

Intended for turning operations, the insert is suitable for both external and internal applications when matched with the correct holder and cutting data. The GH330 grade supplements the insert geometry by supplying the desired mix of wear resistance, toughness and cutting-edge stability, so it is a good starting point for general-purpose turning. For optimal results, pair the insert with a holder that matches the ISO designation, confirm the clamping system accommodates the cylindrical hole and select cutting parameters based on material, rigidity and stability of the set-up to achieve the best balance of productivity and surface quality.
