We manufacture and wholesale indexable carbide inserts — turning, milling, grooving, drilling and threading geometries — made from 100% virgin tungsten carbide. We supply standard ISO shapes (CNMG, TNMG, WNMG, SNMG, DNMG, VNMG, CCMT and more) and custom grades, chipbreakers and coatings on request.

Yes. We produce custom inserts from your drawings, samples or specifications, including grade, chipbreaker, coating (CVD/PVD) and tolerance, and we support private-label packaging. OEM/ODM is a core part of our business.

Among suppliers that use 100% virgin tungsten carbide, we offer the best price-performance in Zhuzhou, China’s largest cemented-carbide production base. We do not compete on price with suppliers that use recycled scrap carbide; our price benchmark is other virgin-material producers, where we are the most cost-competitive.

Production follows ISO 9001 with SGS-verified processes. Every insert is made from virgin tungsten carbide — never recycled scrap — with controlled grain size, coating adhesion and dimensional accuracy. We are an Alibaba Verified Supplier.

Yes. Even India’s notoriously price-focused bulk buyers — who benchmark suppliers aggressively — purchase our inserts in volume and report that our quality beats competitors’.

MOQ is 2,000 pieces per item, packed 10 pieces per plastic box (one carton = 2,000 pieces). Sampling and production lead times are confirmed per order.
