Tungaloy TNGG160404L-P GH110 Turning Insert
PVD Coated GH110 Grade | Precision -P Chipbreaker | 0.4mm Left-Hand Radius
How can I improve tool life during high-precision steel finishing?
The Tungaloy TNGG160404L-P GH110 is a high-precision left-hand PVD coated carbide insert specifically engineered for the fine finishing of ISO P (Steel) and ISO K (Cast Iron) materials. Utilizing the advanced GH110 grade, this insert offers an exceptional balance of edge sharpness and wear resistance, allowing for consistent dimensional control over long production batches. The Left-hand (L) orientation combined with a 0.4mm corner radius (04) makes it ideal for specialized CNC setups requiring high surface integrity and precise profiling. 100% Made in Japan, it delivers the industrial reliability required for modern high-speed turning.
GH110 PVD Coating
A specialized high-hardness PVD coating that resists flank wear and cratering. GH110 is designed to maintain a sharp edge even when machining abrasive materials.
-P Precision Breaker
The -P geometry is optimized for ultra-light depths of cut. It ensures superior chip control, preventing the common "bird-nesting" issues associated with fine finishing passes.
G-Class Accuracy
Fully ground periphery ensures high repeatability and tight tolerances. This minimizes machine downtime during insert changes in high-precision environments.

8. FAQ - Precision Tooling Support
Q: Why use GH110 instead of a cermet grade?
A: GH110 (PVD Carbide) is tougher than cermet. It is better for applications where the setup might not be perfectly rigid or where interrupted cuts occur during finishing.
Q: What tool holder is needed for TNGG160404L-P?
A: This is a Left-hand (L) insert. You must pair it with a Left-hand external holder (WTJNL) or an internal boring bar (S-WTJNL).
Tech Tip: Optimizing Carbide Finishing
Maintain stable cutting speeds and ensure adequate coolant for the best finish with **GH110**. This PVD grade is designed for precision surface integrity. **Tungaloy Japan** - Excellence in high-hardness edge technology.
