TNMG 160404 GH330 indexable turning insert by Tungaloy — triangular ISO insert for external and internal turning, 60° geometry

TNMG160404 GH330 Tungaloy turning insert is an ISO-standard triangular indexable insert designed for general turning operations, offering balanced wear resistance and edge stability for a wide range of machining tasks.

• ISO-standard triangular insert with hole
• GH330 wear-resistant Tungaloy grade
• 60° geometry for stable cutting
• 0.4 mm corner radius for versatile finishes

Reliable wear resistance for continuous production

The GH330 grade, developed by Tungaloy, combines enhanced wear resistance with sufficient toughness to resist chipping under normal to demanding turning conditions. The carbide substrate ensures consistent cutting behaviour over multiple indexings, which reduces changeover frequency and supports a smoother production flow. Choosing this grade helps to extend tool life while maintaining part quality, especially when combined with the appropriate chipbreaker and machining parameters.

Secure clamping and ISO compatibility for predictable setup

The triangular form with a cylindrical hole and the ISO designation ensure compatibility with a wide range of standard external holders and boring bars. The 60° cutting angle and specified 0.4 mm corner radius facilitate repeatable seating and predictable cutting engagement. Compatibility is determined by insert form, clearance angle, tolerance class, fastening method, size and thickness; matching these parameters reduces setup time and avoids unexpected runout or instability.

Optimised geometry for consistent chip control and surface finish

The double-sided chipbreaker geometry is designed to manage chips effectively while offering two usable cutting edges per side, making the insert economical in use. The geometry supports both external and internal turning; selecting the correct chipbreaker and grade for the workpiece material and the process stability leads to improved surface finish and reduced risk of built-up edge. For flexible workshop routines, this insert provides a balance between productivity and finish quality.

FAQ

What materials is this insert intended for?
The TNMG160404 GH330 Tungaloy insert is intended for turning applications where wear resistance and edge stability are priorities; the grade complements the insert geometry and should be selected alongside the appropriate chipbreaker for the specific workpiece material.

Is the insert compatible with standard ISO holders?
Yes, the TNMG160404 conforms to ISO dimensions and the triangular form with a cylindrical hole is compatible with holders and boring bars designed for TNMG inserts, provided the holder matches form, size and fastening method.

How many cutting edges are available per insert?
With the double-sided chipbreaker geometry, multiple usable cutting edges are available; the exact count depends on indexing practice, but the design is economical and intended for multiple indexings.

What surface finishes can be achieved with this geometry?
The 0.4 mm corner radius and optimised chip control support good surface finishes in both external and internal turning when combined with appropriate feeds, speeds and a matching chipbreaker.

What identifiers should be quoted when ordering?
Quote the designation TNMG160404 GH330, the article number 6808378 and, if needed, the manufacturer SKU TUN6808378 to ensure correct supply.
