TNMG 160404 GH330 Tungaloy indexable insert for Turning — triangular ISO insert, 0° relief, 60° lead angle

The TNMG160404 GH330 Tungaloy indexable insert is an ISO-standard triangular cemented carbide insert developed for general turning applications, offering a balanced mix of wear resistance and edge stability.

• ISO triangular insert TNMG 160404
• GH330 carbide grade for wear resistance
• 0° relief with 60° cutting angle
• Cylindrical-holed, double-sided chipbreaker

Consistent edge life and process reliability

The combination of GH330 cutting grade and cemented carbide substrate delivers stable wear behaviour and predictable tool life under industrial turning conditions. The grade is tailored to balance hardness and toughness, which reduces unexpected edge failure and enables longer intervals between indexings. For shop-floor planning this translates into fewer interruptions, consistent component quality and improved overall machining economy.

Geometry engineered for accurate changeovers

The triangular geometry with an inscribed circle dimension of 16 mm, a plate thickness of 4.76 mm and a 0.4 mm corner radius ensures reliable seating and repeatable cutting conditions in ISO-compatible holders. The cylindrical hole and the specified 0° relief with a 60° lead angle permit secure clamping and predictable chip flow; compatibility with a holder is determined by form, clearance angle, tolerance class, fastening method, size and thickness, so changeovers remain quick and deterministic.

Machining performance across common turning tasks

Designed for both external and internal turning, the insert features a double-sided chipbreaker that supports controlled chip formation and evacuation in a range of feed and depth-of-cut conditions. Selecting the correct chipbreaker and grade combination according to workpiece material and machining stability helps to reduce built-up edge and improve surface finish, while the ISO format simplifies stockkeeping and allows fast replacement during production.

Economic advantages through modular tool systems

As part of an ISO turning insert system — comprising the indexable plate, a matching external holder or boring bar, a shim/clamp set and replacement screws — this insert supports standardised tooling inventories and fast maintenance procedures. The predictable wear behaviour of the GH330 grade contributes to lower tooling costs per component and a more efficient production flow, making it suitable for batch and continuous turning operations where uptime and repeatability are priorities.

FAQ

What materials is the TNMG160404 GH330 insert suited for?
The TNMG160404 GH330 insert is intended for general turning tasks; the GH330 grade is developed to provide a wide coverage of workpiece materials when the appropriate chipbreaker and cutting data are selected.

How does the GH330 grade benefit production runs?
GH330 offers a balance of wear resistance and toughness, which helps to maintain edge stability during extended runs and reduces the frequency of unscheduled indexings.

Is the insert indexable on both sides?
Yes, the plate is double-sided with a chipbreaker on each usable face, allowing rotation and re-indexing to extend the useful life of the insert.

Which holder characteristics need to be checked for compatibility?
Compatibility depends on holder form, clearance/relief angle, tolerance class, fastening method, and the insert’s size and thickness; ensure the external holder or boring bar matches these parameters.

What does the designation TNMG160404 indicate?
TNMG160404 is the ISO code for the insert family and includes the geometry and dimensional cues (such as the size and corner radius) used to identify the plate within the ISO-standard range
