TNMG 160408 GH330 TNMG Turning Insert – 60° triangle, 0.8 mm radius | Tungaloy

A TNMG160408 GH330 ISO turning insert designed for external and internal turning where consistent edge life and reliable chip control are required.

• ISO triangular insert TNMG 60° geometry
• GH330 carbide grade for wear resistance
• 0.8 mm corner radius for precise profile
• Double-sided with cylindrical hole for secure mounting

Consistent performance through a wear‑resistant grade

The cutting grade GH330 is a Tungaloy-engineered carbide designed to combine wear resistance with sufficient toughness for a broad range of turning tasks. This balance reduces unexpected edge breakage and extends effective cutting time, which translates into fewer indexings and less machine downtime. The applied material science reduces flank wear under standard feed and speed ranges, supporting stable component tolerances and predictable dressing intervals for production environments.

Geometry and clamping that preserve accuracy

The 60° triangle insert with a 0.8 mm corner radius and 4.76 mm thickness provides a compact cutting edge suited to profile and finishing passes where dimensional control matters. The insert is double-sided, offering two usable edges per side, and is provided with a cylindrical hole to match common ISO clamping systems; compatibility with a specific holder depends on form, clearance angle, tolerance class, fixing method, size and thickness. The robust edge geometry and secure mounting together contribute to reduced vibration and improved surface finish when the correct holder and clamp set are selected.

Practical advantages in daily turning operations

Designed for general turning, this indexable insert performs in both external and internal operations when paired with an appropriate holder and stable setup. The ISO format enables quick replacement: only the insert is changed rather than the whole tool, which is a cost‑effective strategy for batch production and jobbing shops alike. The double-sided chipbreaker gives flexibility: the same insert supports varied chip control strategies depending on feed, depth of cut and workpiece material, reducing inventory complexity while maintaining process reliability.

Selection guidance and process reliability

Selection of the correct chipbreaker and grade should follow the workpiece material, machining type and fixture stability. When paired with a matched external holder, clamp set and mounting screw, the system ensures process reliability and repeatable edge performance. For less experienced staff, indexable formats simplify tool handling: inserts are easy to identify by ISO designation and the TNMG geometry is widely supported by toolholders, enabling fast setup and consistent results across shifts.

FAQ

What materials is this insert suited for?
The TNMG160408 GH330 insert, with its GH330 carbide composition, is intended for a broad range of turning tasks and offers good wear resistance on common steels and general engineering materials when the correct cutting data and holder stability are observed.

How many cutting edges are available per insert?
The insert is double-sided, providing multiple usable edges; this increases edge life per component and reduces the frequency of insert changes on the toolholder.

Which insert geometry does TNMG denote?
TNMG indicates a triangular insert with a 60° included angle; this geometry is suitable for general turning and offers a balance between strength and accessibility for profile and finishing passes.

How is compatibility with the toolholder determined?
Compatibility is determined by insert form, clearance angle, tolerance class, fixing method, overall size and thickness; confirm these parameters against the chosen external holder or boring bar before mounting.

Is the insert supplied with coating information?
The offered item is specified by the Tungaloy GH330 grade; customers requiring detailed coating or microstructure data should request the technical datasheet for the GH330 grade.
