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.

Technical Feature	Metric (ISO)	Imperial (ANSI)
Standard Model	TNGG160402R-P	TNGG 330.5R-P
Inscribed Circle (IC)	9.525 mm	3/8"
Thickness (S)	4.76 mm	3/16"
Corner Radius (RE)	0.2 mm	0.008"

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.

Global CNC Professional Feedback

⭐⭐⭐⭐⭐ "High Speed, Low Wear" - Steven B., USA
"Switched to GH330 for our finish runs on 316 stainless. The wear resistance at high speeds is significantly better than our previous grade."

⭐⭐⭐⭐⭐ "Mirror Surface" - Karl H., Germany
"Tungaloy's 0.2mm radius is incredibly sharp. We achieved a mirror finish on small carbon steel pins with zero vibration."

⭐⭐⭐⭐ "Great Chip Flow" - T. Yamamoto, Japan
"The -P chipbreaker works exactly as described. Even at 0.1mm depth, chips are controlled. Fast shipping from Beyond team."

⭐⭐⭐⭐⭐ "Genuine Product" - Luca M., Italy
"Received original factory-sealed boxes. The technical parameters provided helped us dial in our CNC setup immediately."

⭐⭐⭐⭐⭐ "B2B Choice" - Rajesh K., India
"Reliable source for authentic Tungaloy inserts. Consistent performance on precision stainless steel parts."

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.

Technical FAQ & Buying Guide

Are your carbide inserts interchangeable with major brands like Sandvik, Iscar, or Kennametal?

Absolutely. Our CNC carbide inserts (including CNMG, WNMG, DNMG, and APMT series) are manufactured strictly adhering to international ISO/ANSI specifications. A CNMG 120408 from OYYU BEYOND will flawlessly fit any standard turning tool holder or indexable tool from major global brands like Sandvik Coromant, Kennametal, Iscar, Walter, or SECO, providing a highly cost-effective premium alternative without sacrificing tolerance or tool life.

How do I choose the correct insert grade and chipbreaker for machining Stainless Steel (M) vs. Carbon Steel (P)?

We offer optimized CVD and PVD multi-layer coatings for different ISO material groups:

For Carbon/Alloy Steel (ISO P): Choose our thick multi-layer CVD coated grades (e.g., Al2O3 + TiN). They provide exceptional crater wear resistance and thermal barriers during high-speed dry or wet roughing.
For Stainless Steel (ISO M): Choose our nano-structured PVD coated grades with sharp, positive chipbreakers (like -TM or -MA). This combination prevents work hardening and effectively controls sticky chips.

What are the recommended cutting speed (Vc) and feed rate (f) parameters to maximize tool life?

The optimal cutting parameters vary depending on the workpiece hardness and operation type:

For General Steel Turnings: Recommended cutting speed ($V_c$) ranges from 150 to 280 m/min, with a feed rate ($f$) of 0.15 to 0.45 mm/rev.
For Stainless Steel Finishing: Recommended cutting speed ($V_c$) is 120 to 200 m/min, with a feed rate ($f$) of 0.10 to 0.25 mm/rev.Always adjust parameters based on early wear patterns: increase $V_c$ if built-up edge occurs, or reduce $V_c$ if severe flank wear is observed.

Do you offer bulk discounts or wholesale pricing for machine shops and distributors?

Yes, we support machine shops, distributors, and global buyers with tiered wholesale pricing and competitive volume discounts. We also provide OEM custom manufacturing solutions for tool holders and carbide inserts based on your technical drawings. Contact our team to request a quick B2B quotation.
