Frequently Asked Questions (FAQ)
What materials can these carbide inserts machine?
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.
How long is the service life of your tools compared to traditional ones?
Due to the ultra-high hardness (HRA 90+) and advanced PVD coatings, our inserts typically exhibit a service life 3 to 10 times longer than traditional high-speed steel cutting tools.
Can you provide custom models for special machining scenarios?
Yes, we offer customization services for insert dimensions (thickness, groove width, nose radius), edge angles, and specialized coating types to meet unique requirements like deep grooving or complex threads.
Are your inserts compatible with international tool holders?
Our products are manufactured according to ISO, ANSI, and JIS international general standards, ensuring they are fully compatible with mainstream tool holders on the market.
What is the expected delivery time for international orders?
Through our partnerships with DHL, FedEx, and UPS, most international orders for key routes are delivered within 3-7 workdays, featuring full logistics tracking and professional packaging.
Do you use recycled materials in your carbide production?
No, we use 100% virgin raw materials with strict incoming quality inspections to ensure the highest stability, impact resistance, and red hardness of every insert.
