Tungaloy TNGG160402R-P GH330 Turning Insert
PVD Coated Grade GH330 | Precision -P Chipbreaker | 0.2mm Right-Hand Radius
What is the best PVD grade for high-speed finishing of alloy steel?
The Tungaloy TNGG160402R-P GH330 is a high-precision right-hand PVD coated carbide insert specifically optimized for finishing operations in ISO P (Steel) and ISO M (Stainless Steel). Utilizing the GH330 grade, this insert features a specialized coating that excels in high-speed applications while maintaining a sharp cutting edge. The 0.2mm corner radius (02) and the -P precision chipbreaker allow for ultra-fine depths of cut with perfect chip control. 100% Made in Japan, it is the industrial benchmark for CNC professionals seeking precision dimensional accuracy and reduced tool pressure on thin-walled parts.
GH330 PVD Coating
Designed for high-speed machining, the GH330 grade offers excellent thermal stability and oxidation resistance. It ensures long tool life even when cutting heat-resistant alloy steels.
-P Precision Breaker
The -P chipbreaker is engineered for ultra-light finishing passes. It prevents chip entanglement and bird-nesting, ensuring a scratch-free surface on the workpiece.
0.2mm Fine Radius
The sharp 0.2mm radius significantly reduces radial cutting forces, making it perfect for profiling and machining small-diameter or delicate components.

Recommended Parameters (GH330 Grade)
-
Cutting Speed (Vc): 100 - 220 m/min (Optimized for Finishing)
-
Feed Rate (f): 0.03 - 0.12 mm/rev (For Superior Ra)
-
Depth of Cut (ap): 0.1 - 0.8 mm
*B2B Insight: GH330 excels in higher temperatures compared to GH110. It is the preferred choice for high-speed finishing where surface heat dissipation is critical.*
4. Primary Applications
- Fine finishing of stainless steels and high-alloy steels.
- Profiling of precision gears and hydraulic components.
- Continuous high-speed turning of small carbon steel shafts.
- Internal boring where low cutting pressure is mandatory.
5. Tool Compatibility
Universal TN** 1604 pocket compatibility. Pairs with WTJNR or MTJNR Right-hand external tool holders. Excellent for use with S-WTJNR boring bars.

8. FAQ - Precision Tooling Support
Q: What is the difference between GH330 and GH110?
A: GH330 is optimized for higher cutting speeds and better heat resistance, making it superior for stainless steels and high-temp alloys, whereas GH110 is often preferred for toughness in general steel.
Q: Can I use this R-P insert in a left-hand holder?
A: No, this is a Right-hand (R) insert. It must be paired with a Right-hand holder (WTJNR/MTJNR) to ensure the chipbreaker faces the workpiece correctly.
Tech Tip: Achieving the Perfect Ra
For the best surface roughness with **GH330**, ensure your spindle speed is high enough to reach the recommended Vc. Low speeds can lead to built-up edge and surface dullness. **Tungaloy Japan** - Leading the world in precision finishing.
