Carbide insert is the indexable insert widely used in CNC lathes, mainly applications including metal turning, milling, threading and drilling. Cemented carbide inserts have much advantage in high efficiency which can be four times more than traditional welding blade or alloy blade in real production.
Direct from our factory in Zhuzhou, Hunan — the carbide capital of China.
Founded in 2018 in Zhuzhou, China's cemented-carbide capital. Real workshop photos, production videos and machining case studies are available for every product line on request.
Our team is trained in materials science and mechanical engineering with 10+ years of carbide experience. Send your workpiece material and cutting conditions, and we will recommend the right grade and geometry for free.
CNC grinding and PVD/CVD coating lines run under a strict quality system. Every batch ships with an inspection report, and third-party testing (SGS / TÜV) is welcome before shipment.
Factory-direct pricing with no hidden fees. A formal sales contract covers every order, verified quality issues are replaced free of charge, and orders ship worldwide within 3–7 days.
Every carbide insert we ship is produced in our own workshop in Zhuzhou — from tungsten carbide powder pressing and sintering to CNC grinding and PVD/CVD coating. This in-house control covers turning (CNMG, WNMG, TNMG, SNMG), milling (APMT, APKT, RPMT), drilling and grooving grades, so coating and geometry can be matched to your workpiece material. The photos below are taken on our production and quality-inspection lines.
