Tungaloy TNGG160404R-P GH330 Turning Insert
PVD Coated Grade GH330 | Precision -P Chipbreaker | 0.4mm Right-Hand Radius
What is the best PVD grade for high-speed finishing on alloy steel?
The Tungaloy TNGG160404R-P GH330 is a high-performance 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 0.4mm corner radius (04) and the -P precision chipbreaker allow for fine depths of cut with perfect chip control. 100% Made in Japan, it is the industrial choice for CNC professionals seeking precision dimensional accuracy and reduced tool pressure on delicate components.
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 Finishing Geometry
The -P chipbreaker is engineered for light finishing passes. It prevents chip entanglement and bird-nesting, ensuring a scratch-free surface on the workpiece.
0.4mm Precision Radius
The 0.4mm radius balances edge strength and finishing quality, making it perfect for profiling and machining intricate components with high gloss requirements.

8. FAQ - Professional Support
Q: Is GH330 better than GH110 for high-temp alloys?
A: Yes. GH330 is designed with higher thermal stability, making it more effective for stainless steels and alloys that generate significant heat during machining.
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) to ensure the chipbreaker is oriented correctly to the workpiece.
Tech Tip: Achieving High Surface Gloss
For the best surface roughness with **GH330**, prioritize a high cutting speed (Vc) and ensure the cutting edge remains cool with proper coolant delivery. **Tungaloy Japan** - Excellence in precision finishing technology.
