Tungaloy TNGG160404L-P TH10 Turning Insert
Uncoated Micrograin TH10 | Precision -P Chipbreaker | 0.4mm Left-Hand Radius
What is the best uncoated carbide insert for aluminum and brass finishing?
The Tungaloy TNGG160404L-P TH10 is a high-precision left-hand uncoated carbide insert, specifically designed for finishing non-ferrous metals such as aluminum alloys, brass, and copper. Utilizing the TH10 micrograin grade, it provides an exceptionally sharp cutting edge and high resistance to built-up edge (BUE). The 0.4mm corner radius (04) and the -P precision chipbreaker ensure excellent surface integrity and chip evacuation in light finishing applications. 100% Made in Japan, this insert is the industrial standard for achieving a mirror-like finish on non-ferrous workpieces.
TH10 Micrograin Carbide
An uncoated grade with superior hardness and wear resistance. Its micrograin structure allows for an ultra-sharp edge, critical for cutting soft, gummy materials without burrs.
-P Finishing Geometry
Engineered for precision and light loads. The -P breaker keeps cutting forces low, preventing workpiece deformation while effectively breaking chips at low feed rates.
Precision Ground Finish
G-class tolerance periphery ensures that every insert maintains the exact same dimensions, allowing for seamless replacement without readjusting CNC offsets.

Recommended Cutting Parameters (TH10 Uncoated)
-
Cutting Speed (Vc): 150 - 600 m/min (Aluminum/Brass)
-
Feed Rate (f): 0.05 - 0.15 mm/rev (For Mirror Finish)
-
Depth of Cut (ap): 0.1 - 1.0 mm
*Pro Tip: TH10 is an uncoated grade. It is not recommended for titanium or high-temp alloys where high thermal loads are present. Use high-speed machining for best aluminum surface gloss.*
4. Primary Applications
- Precision finishing of high-silicon aluminum alloys.
- Turning and profiling of brass, bronze, and copper parts.
- Machining non-metallic materials (plastics/fiber-reinforced polymers).
- Boring operations where sharp edges are required to prevent smearing.
5. Tool Compatibility
Compatible with standard TN** 1604 tool pockets. Specifically designed for WTJNL or MTJNL Left-hand external tool holders and S-WTJNL internal boring bars.

Feedback from CNC Machinists
⭐⭐⭐⭐⭐ "Mirror Finish on Aluminum" - Chris B., USA
"This TH10 grade is amazing for 6061-T6 aluminum. The edge stays sharp and we get a beautiful finish every time. No build-up issues."
⭐⭐⭐⭐⭐ "Best for Fine Brass Work" - Hans W., Germany
"Original Tungaloy quality. Using the left-hand holder with this insert for intricate brass profiling. Very stable dimensions."
⭐⭐⭐⭐ "Great Chip Control" - Kenji S., Japan
"The -P chipbreaker works exactly as expected. We used to have bird-nesting on light cuts, but this insert solved it. Excellent support from Beyond."
⭐⭐⭐⭐⭐ "Fast Fulfillment" - Marco D., Italy
"Ordered a bulk set for our shop. Shipping was fast and the product is 100% genuine. TH10 is the best for our non-ferrous line."
⭐⭐⭐⭐⭐ "Professional Grade" - Arjun R., India
"Superior sharpness compared to cheaper alternatives. This is real Japan-made tooling that saves us time on reworking surfaces."
8. FAQ - Expert Tooling Advice
Q: Can I use TH10 on carbon steel?
A: We do not recommend TH10 for steel. It is an uncoated grade meant for non-ferrous metals. For steel finishing, please choose GH110 or GH330 coated grades.
Q: Does this work in a Right-hand tool holder?
A: No. This is a Left-hand (L) insert. You must pair it with a Left-hand (L) tool holder to ensure the geometry and chipbreaker function correctly.
Tech Tip: Uncoated Carbide Care
Since **TH10** is uncoated, it relies on its extreme sharpness to cut cleanly. Ensure high coolant pressure to wash away aluminum chips and prevent heat build-up. **Tungaloy Japan** - Precision in every cut.
