Our ISO metric threading inserts stand out in global industrial procurement with balanced precision, durability and cost performance, perfectly tailored for mass CNC metric thread production. Strictly following ISO 60° metric thread standards, every insert delivers consistent tooth profile, pitch accuracy and 6H/6g thread tolerance stability, ensuring high gage pass rates for finished threads without secondary finishing.

We adopt premium fine-grain carbide substrates and customized professional grades, paired with multi-layer PVD/TiAlN coatings. This design greatly boosts wear resistance, thermal stability and chipping protection, extending tool life significantly when threading carbon steel, alloy steel, stainless steel and cast iron. Optimized chip breaker geometry effectively eliminates built-up edge, thread burrs and vibration marks, maintaining smooth thread flank surface even during long continuous or frequent start-stop machining.

We cover full-range standard metric pitches from fine to coarse, supporting both internal and external threads, and fully interchange with mainstream global tool holders and brands. Flexible small-batch trial orders, stable bulk quality, customizable special tooth profiles and exclusive tolerance adjustments meet diverse industrial demands. Supported by complete inspection reports, standardized export packaging and professional after-sales technical guidance, our inserts help overseas buyers lower tool costs and improve production efficiency steadily.
