💎 Core Performance Advantages:

🚀 Ultra-high Hardness

Hardness can reach above HRA 90. Resists high-temperature wear and oxidation, offering a service life 3–10 times longer than traditional tools.

🌡️ High-temperature Stability

Maintains performance at 800–1000 °C. Ideal for high-speed cutting and dry cutting without deformation.

🎯 Precise Accuracy

High-precision grinding ensures sharp edges and superior finish (Ra ≤ 0.8 μm) for stringent IT5–IT7 tolerance grades.

Frequently Asked Questions (FAQ)
1. What materials are these carbide inserts suitable for?
Our inserts are designed for a wide range of materials including carbon steel, alloy steel, stainless steel, cast iron, non-ferrous metals (aluminum/copper), superalloys, and titanium alloys.
2. How do you ensure the high wear resistance of the threading inserts?
We use 100% virgin tungsten carbide substrate combined with advanced PVD coatings like TiN, TiAlN, and AlCrN, which allows the hardness to reach above HRA 90.
3. Are these inserts compatible with my existing tool holders?
Yes, our products are manufactured according to ISO, ANSI, and JIS international standards, making them fully compatible with most standard tool holders on the market.
4. Can I request a customized insert for specific machining needs?
Absolutely. We offer customization services for dimensions (thickness, nose radius), edge angles, and specialized coating types to match your unique machining scenarios.
5. What is the typical lead time for international shipping?
Through our partnerships with DHL, FedEx, and UPS, most international deliveries are completed within 3-7 workdays for major global routes.
6. Do you provide technical support for tool selection?
