Ultra-high Hardness

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

High-temp Stability

Outstanding red hardness. Maintains performance at 800–1000 °C. Ideal for high-speed cutting and dry cutting.

Precise Accuracy

High-precision grinding ensures sharp edges and smooth chip evacuation. Meets tolerance grades IT5–IT7.

Impact Resistance

Optimized alloy composition and edge design enhance toughness for heavy-load rough machining or high-precision finish machining.

Frequently Asked Questions

Q1: What materials can these carbide inserts machine? Our inserts are suitable for carbon steel, alloy steel, stainless steel, cast iron, non-ferrous metals (aluminum/copper), superalloys, and titanium alloys.

Q2: Are your inserts compatible with my existing tool holders? Yes, our products comply with ISO, ANSI, and JIS international standards and can directly replace inserts of the same standard models.

Q3: What is the benefit of the PVD coating? PVD coatings like TiAlN and AlCrN provide high-temperature resistance and wear resistance, significantly extending tool life during high-speed cutting.

Q4: Can you provide customized inserts for specific projects? Absolutely. We offer customization for dimensions, edge angles, and specialized alloy formulas for complex machining scenarios like deep grooving.

Q5: How long does international delivery take? Major routes typically take 3-7 workdays via couriers like DHL or SF International. Bulk orders are balanced for speed and cost.

Q6: What is the hardness rating of these inserts? Most of our tungsten carbide inserts feature a hardness rating of HRA 90-95+, far exceeding standard high-speed steel tools.
