Tungaloy TNGA160404 / TNGA160408 LX11 Ceramic Inserts

High-Speed SiAlON Ceramic | LX11 Grade for Cast Iron | Precision Japan Tooling

What is the best ceramic insert for high-velocity cast iron machining?

The Tungaloy TNGA160404 and TNGA160408 LX11 series represents the pinnacle of high-speed turning technology for gray and ductile cast iron. Unlike standard carbide, the LX11 SiAlON ceramic grade maintains extreme hardness at elevated temperatures, allowing for cutting speeds far beyond traditional limits. Whether you require the fine precision of a 0.4mm radius (04) or the edge strength of a 0.8mm radius (08), these negative triangular inserts provide the thermal stability needed for heavy-duty industrial applications. 100% Made in Japan, they are engineered to reduce cycle times and maximize throughput in high-volume production.

LX11 SiAlON Grade

A specialized ceramic with excellent fracture toughness and thermal shock resistance. Perfect for high-speed continuous or light interrupted cuts in Cast Iron (ISO K).

High Speed Velocity

Engineered to run at speeds up to 1000 m/min. This grade significantly reduces cycle times compared to coated carbide inserts in the same application.

Negative Geometry

The double-sided triangular design provides 6 usable cutting edges, offering exceptional cost-efficiency and a robust edge for roughing to finishing.

Ceramic Cutting Recommendations (ISO K - Cast Iron)

  • Cutting Speed (Vc): 400 - 1000 m/min (High-speed ceramic zone)
  • Feed Rate (f): 0.10 - 0.40 mm/rev
  • Depth of Cut (ap): 0.2 - 2.5 mm

*Note: Ceramic inserts thrive on heat. Dry machining is often recommended for gray cast iron to avoid thermal cracking.*

4. Primary Applications

  • High-speed finishing of automotive brake discs.
  • Turning gray cast iron and ductile iron engine components.
  • Machining large-diameter cast iron rollers.
  • Ideal for mass production requiring long tool life.

5. Tool Compatibility

Fits all standard TNGA 1604 / TNGA 33x holders. Optimized for WTJNR/L or DTGNR/L heavy-duty external turning holders.

Global Machinist Reviews

⭐⭐⭐⭐⭐ "Incredible Speed" - Dieter S., Germany
"Switched to LX11 for brake disc turning. We increased our cutting speed from 300 to 800 m/min. Total game changer for throughput."

⭐⭐⭐⭐⭐ "Great Heat Resistance" - Robert B., USA
"Running dry on gray iron, the edge holds up perfectly. The 0.8 radius (160408) is very robust for roughing."

⭐⭐⭐⭐ "Smooth Finish" - Akira H., Japan
"Excellent precision on ductile iron. The TNGA160404 provides a very clean surface finish even at high velocities."

⭐⭐⭐⭐⭐ "B2B Support" - Marco G., Italy
"Beyond OYYU team provided the exact cutting parameters for our engine block project. Original Tungaloy quality."

⭐⭐⭐⭐⭐ "Reliable Grade" - Vikram D., India
"LX11 is much tougher than other ceramics we've tried. Fewer edge chippings during interrupted cuts on cast parts."

8. FAQ - Ceramic Machining

Q: Should I use coolant with LX11 ceramic?

A: For gray cast iron, dry machining is typically better to prevent thermal shock. If coolant is necessary, ensure it is high-volume and continuous.

Q: What is the difference between TNGA160404 and 160408?

A: The '04' has a 0.4mm radius for finer finishing and lower cutting pressure, while the '08' has a 0.8mm radius for better edge strength and faster feeds.

Tech Tip: Ceramic vs. Carbide

While carbide loses its hardness at high temperatures, **LX11 Ceramic** actually becomes more effective. Use this grade for high-velocity cast iron turning to maximize your CNC's output. **Tungaloy Japan** - Leading the way in ceramic innovation.

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.

When will my order ship and arrive?

According to our shipping policy, orders are typically processed and shipped within 1–3 business days after confirmation.
