Tungaloy TNGG160402R-P GH110 Turning Insert
PVD Coated Grade GH110 | Precision -P Chipbreaker | 0.2mm Right-Hand Radius
What is the best PVD coated insert for high-precision finishing on steel?
The Tungaloy TNGG160402R-P GH110 is a high-precision right-hand PVD coated carbide insert engineered for superior finishing in ISO P (Steel) and ISO K (Cast Iron) machining. Utilizing the GH110 grade, this tool features an extremely sharp cutting edge combined with high wear resistance, making it ideal for maintaining tight tolerances over long production runs. The Right-hand (R) orientation and the fine 0.2mm corner radius (02) allow for intricate profiling and superior surface gloss. 100% Made in Japan, it is the professional choice for CNC turning where dimensional accuracy and edge longevity are the highest priorities.
GH110 Wear Resistance
GH110 is a specialized PVD grade that offers a perfect balance of toughness and hardness. It effectively resists flank wear even in abrasive machining environments.
-P Precision Breaker
The -P chipbreaker is specifically designed for light finishing. It ensures excellent chip control at very shallow depths of cut, preventing surface damage from long chips.
Sharp Ground Edge
Fully ground G-class tolerance ensures high repeatability and minimal vibration, resulting in superior surface Ra values and dimensional consistency.

Recommended Parameters for GH110
-
Cutting Speed (Vc): 80 - 180 m/min (Balanced Performance)
-
Feed Rate (f): 0.03 - 0.12 mm/rev (Mirror Finish Zone)
-
Depth of Cut (ap): 0.1 - 0.8 mm
*B2B Recommendation: GH110 is highly effective at resisting wear in dry cutting environments, though light oil mist can further enhance surface gloss.*
4. Primary Applications
- High-precision finish turning of alloy and tool steels.
- Final profiling for small automotive and hydraulic components.
- Machining of small-diameter shafts with tight tolerance requirements.
- Continuous turning operations in ISO K (Cast Iron).
5. Tool Compatibility
Standard TN** 1604 interface. Pairs perfectly with WTJNR or MTJNR Right-hand external tool holders. Also compatible with S-WTJNR boring bars for internal profiling.

8. FAQ - Professional Support
Q: Is GH110 better than cermet for finishing?
A: GH110 (PVD Carbide) is tougher than cermet. It is better for applications requiring edge strength or when dealing with interrupted cuts, while cermet provides a higher mirror finish in continuous cuts.
Q: What tool holder should I use with TNGG160402R-P?
A: This is a Right-hand (R) insert. You must pair it with a Right-hand external holder (like WTJNR or MTJNR) to ensure the chipbreaker is correctly oriented.
Tech Tip: Optimizing Tool Life with GH110
For maximum tool life, ensure your setup is rigid and prioritize consistent cutting speeds. GH110 thrives where edge sharpness must be maintained against flank wear. **Tungaloy Japan** - Excellence in PVD technology.
