SNMG 120404 GH330 turning insert — Tungaloy, ISO 120404, 90° square

The SNMG 120404 GH330 is an ISO-standard turning insert designed for general external and internal turning applications, offering a balance of wear resistance and edge stability for productive metalcutting operations.

• ISO 120404 square turning insert
• GH330 Tungaloy grade for wear resistance
• Double-sided chipbreaker for versatile use
• 0.4 mm corner radius, 90° geometry

High-performance grade for sustained productivity

The GH330 grading, paired with cemented carbide, delivers consistent wear resistance and edge stability under standard turning conditions. This combination is designed to extend service intervals and support longer tool life, which contributes to reduced downtime and lower tool costs per component. The ISO designation ensures interchangeability with holders that match form, tolerance class, fastening and thickness, enabling predictable performance in serial production.

Quick system integration and predictable set-up

Compatibility is governed by form, rake, tolerance class, fastening, size and thickness, so the insert integrates smoothly into existing toolholders when those parameters match. The 4.76 mm plate thickness and 12 mm inscribed circle make the insert straightforward to seat in compatible clamping systems. The central cylindrical hole supports secure fastening, while the rake angle 0° maintains a neutral cutting geometry useful for stable chip flow and repeatable set-ups.

Geometry engineered for chip control and surface quality

The double-sided chipbreaker geometry and a 0.4 mm corner radius combine to improve chip formation and evacuation during turning. The square, 90° insert shape provides robust corner support for external operations and adequate stability for light internal cuts, promoting better surface finishes and consistent dimensional results. Standard ISO form factor facilitates fast index changes, reducing non-productive time during tool replacement.

FAQ

What materials is this insert suitable for?
The SNMG120404 GH330 insert is designed as a general turning grade; the GH330 composition in cemented carbide suits a wide range of steels and common engineering materials under standard cutting conditions.

How does the chipbreaker affect machining?
The double-sided chipbreaker on the SNMG120404 GH330 promotes controlled chip formation and evacuation, which helps maintain surface quality and reduces the risk of built-up edge during continuous turning.

Is the insert compatible with standard ISO holders?
Yes. The SNMG120404 designation follows ISO norms, so the insert fits holders that accept SNMG inserts when form, tolerance class, fastening, size and thickness are matched.

What does the 0.4 mm corner radius mean for finishing?
A 0.4 mm corner radius provides a compromise between tool strength and micro-geometric finish, allowing stable cutting forces while supporting good surface quality in finishing and medium turning passes.

How often can the insert be indexed?
The SNMG-format insert is double-sided, enabling multiple index positions; the exact number of effective edges depends on wear during use and the specific operating conditions.
