Tungaloy TNGG160402L-P GH110 Turning Insert

PVD Coated Grade GH110 | Precision -P Chipbreaker | 0.2mm Left-Hand Radius

What is the best PVD coated insert for high-precision finishing on hardened steel?

The Tungaloy TNGG160402L-P GH110 is a high-performance PVD coated carbide insert specifically developed for precision finishing in ISO P (Steel) and ISO K (Cast Iron) materials. Featuring the GH110 grade, this insert combines a tough carbide substrate with a specialized PVD coating to deliver extreme wear resistance and edge sharpness. The Left-hand (L) orientation and sharp 0.2mm corner radius (02) are optimized for complex profiling and thin-wall machining where vibration must be minimized. 100% Made in Japan, it is the professional choice for CNC turning where surface accuracy and tool longevity are critical.

GH110 PVD Coating

A specialized thin-film PVD coating that maintains a very sharp cutting edge while providing high hardness. Ideal for resisting flank wear in abrasive steel and cast iron applications.

-P Finishing Geometry

The -P chipbreaker is designed for ultra-fine finishing. It ensures stable chip evacuation even at extremely low depths of cut, preventing surface marring from long, stringy chips.

Precision Ground Edge

TNGG inserts are fully ground to ensure high dimensional repeatability, making them perfect for automated CNC production with tight tolerances.

3. Technical Data: Metric vs. Imperial Standards

Technical Feature Metric (ISO) Imperial (ANSI)
Standard Model TNGG160402L-P TNGG 330.5L-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 Finishing Parameters (GH110 Grade)

  • Cutting Speed (Vc): 80 - 180 m/min (Balanced Finishing)
  • Feed Rate (f): 0.03 - 0.12 mm/rev (For Mirror Finish)
  • Depth of Cut (ap): 0.1 - 0.8 mm

*CNC Expert Note: GH110 is a "sharp" grade. Use high speeds to prevent built-up edge and ensure the tool is properly seated in a Left-hand holder (WTJNL).*

4. Primary Applications

  • Precision finishing of alloy and carbon steels.
  • Boring and profiling of small, intricate parts.
  • Machining aesthetic components with high gloss requirements.
  • Stable finishing in semi-hardened materials (up to 45 HRC).

5. Tool Compatibility

Compatible with standard TNGG 1604 pockets. Fits WTJNL or MTJNL Left-hand external tool holders. Excellent for use with S-WTJNL boring bars.

Reviews from Precision CNC Specialists

⭐⭐⭐⭐⭐ "Extreme Edge Sharpness" - Mark S., USA
"The GH110 grade is incredibly sharp. We use this for profiling small components and the tolerance holds perfectly across the entire shift."

⭐⭐⭐⭐⭐ "Great for Profiling" - Dieter K., Germany
"The 0.2mm radius is essential for our medical parts. The PVD coating resists wear much better than uncoated carbide on these alloy steels."

⭐⭐⭐⭐ "Very Stable Dimensions" - Tan H., Singapore
"Consistent results. Beyond OYYU team provided original Japan stock fast. This has become our standard for precision finishing."

⭐⭐⭐⭐⭐ "Perfect Chip Control" - Luca B., Italy
"The -P chipbreaker is excellent for light cuts. No bird-nesting or surface scratches. Very professional tool."

⭐⭐⭐⭐⭐ "Authentic Product" - Arjun R., India
"Received in original factory-sealed boxes. Best technical advice from the Beyond team for our CNC lathe setup."

8. FAQ - Precision Tooling Support

Q: Why use GH110 instead of a standard cermet?

A: GH110 (PVD coated carbide) is tougher than cermet. It is better suited for finishing operations where the setup might be slightly less stable or where interrupted cuts occur.

Q: What holder orientation is needed for TNGG160402L-P?

A: This is a Left-hand (L) insert. It must be paired with a Left-hand holder (such as WTJNL or MTJNL) to ensure the chipbreaker performs correctly.

Tech Tip: Optimizing PVD Carbide Finishes

For the best results with **GH110**, prioritize stability and consistent speed. While cermet gives higher gloss, GH110 provides the reliable edge strength needed for precision tolerances. **Tungaloy Japan** - Leading in edge sharpness and PVD technology.

Technical FAQ & Buying Guide

How do I choose the correct specification?

When choosing CNC cutting tools, check the full model code, dimensions, grade and selected variant before ordering. Do not rely on the product image alone.

How can I check compatibility with my existing setup?

For carbide inserts, tool holders, drills and end mills, compare the mounting dimensions, connection type and manufacturer's specifications with your holder or machine. If you are unsure, share your existing part number and machining application with us before ordering.

What quantity and price unit am I ordering?

Check the product listing for the selling unit, pack quantity and included components. If it is unclear whether the price is per piece or per pack, or whether a tool body and inserts are sold separately, contact us before purchasing.

How should I choose cutting parameters?

Select cutting speed, feed rate and depth of cut using the relevant manufacturer's recommendations for your tool model, workpiece material, machine conditions and coolant method. The same settings are not suitable for every product or application.

Are bulk discounts available?

Our automatic quantity discount is 6% off for 2–9 items and 12% off for 10 or more items, based on the total product quantity in the cart. Other offers may not combine with this discount; check the applicable offer conditions.
