About Zunyi Zhongbo Cemented Carbide Co., Ltd - Cemented Carbide Cutting Tools Supplier in China

Zunyi Zhongbo Cemented Carbide Co., Ltd is a China-based supplier operating from Zunyi, Guizhou province, with 6 active products listed across cemented carbide cutting tools and related wear parts. The catalogue covers indexable carbide turning inserts for steel and for ceramic cutting, carbide inserts for circular saw blades, carbide tips for stump grinder teeth, carbide inserts for cutting wood, and cemented carbide block/bar/plate stock in grades YG8 and YG15. The product mix places the company firmly in the tungsten carbide (WC-Co) cutting tool segment, serving metalworking, woodworking, and land-clearing/machinery end uses. The supplier's portfolio sits within the Tools & Instruments and Building Construction Machineries and Equipments categories, with additional overlap into the printing machinery segment through wear-resistant carbide components. Tungsten carbide with cobalt binder, as used in the YG8/YG15 grades listed for the block/bar/plate stock, is the standard material system for indexable inserts and wear parts, where cobalt content typically ranges from 6% (YG6) up to 15% (YG15) and grain size is controlled to balance hardness (typically HRA 87-92) with transverse rupture strength. The HS code 8209.00 applies to the cemented carbide block/bar/plate stock, which is the standard tariff line for plates, sticks, tips and similar semi-finished carbide articles.

Product Range and Specialties of Zunyi Zhongbo Cemented Carbide Co., Ltd

The catalogue is built around six cemented carbide articles: carbide ceramic cutting turning tool inserts, carbide block/bar/plate stock (HS 8209.00, WC-Co grades YG8/YG15), carbide inserts for wood cutting, turning inserts for steel, circular saw blade carbide inserts, and carbide tips for stump grinder teeth. Together these cover three typical application clusters for a Chinese carbide tool exporter: metalworking indexable inserts (ISO turning grades such as P-series for steel and C-series for cast iron/ceramic-coated variants), woodworking tooling (carbide-tipped circular saw blades and brazed tips for wood cutting), and forestry/earthmoving wear parts (stump grinder teeth and similar ground-engagement tips). Industry context for these categories: indexable carbide inserts are commonly specified by ISO 513 application groups (P for steel, M for stainless, K for cast iron, N for non-ferrous, S for heat-resistant alloys, H for hardened steel) and by chip-breaker geometry (e.g. CNMG, TNMG, WNMG). Woodworking carbide tips for circular saw blades are typically supplied as brazed tips in C1/C2/C3 grades, with grain sizes around 0.8-1.5 micrometres and hardness in the HRA 89-92 range. Stump grinder teeth use coarser-grain, higher-cobalt grades (YG8, YG11, YG15) for impact resistance, with cobalt content of 8-15% by weight. Block, bar and plate stock (HS 8209.00) is sold as semi-finished stock for tool makers to grind their own profiles, with standard dimensions in lengths of 100-330 mm, widths of 10-100 mm, and thicknesses of 3-40 mm depending on grade.

Trade and Export Information - Zunyi Zhongbo Cemented Carbide Co., Ltd

Cemented carbide cutting tools and wear parts from Chinese manufacturers such as this one are typically exported to industrial buyers in Southeast Asia, the Middle East, Africa, South America, and Eastern Europe, where metalworking, woodworking, and construction/forestry machinery sectors rely on cost-effective indexable tooling and replacement wear parts. The main HS code families involved are 8209.00 (plates, sticks, tips and similar articles of tungsten carbide), 8208 (interchangeable tools for machine tools, including inserts), and 8418/8466 sub-headings depending on whether inserts are sold loose or fitted to a tool body. Tungsten carbide articles are not generally subject to special import licensing in most markets, but finished inserts with coatings (CVD TiN/TiAlN, PVD coatings) may attract specific chemical declarations under REACH in the EU and TSCA in the United States. Buyers of cemented carbide articles in these categories typically request ISO 9001 quality management certification, material certificates stating WC grain size, cobalt content and hardness (HRA), and dimensional inspection reports. Standard packaging is plastic or foam inner protection inside cardboard cartons, with 5-20 kg per carton typical for inserts and 10-50 kg for block/bar stock, palletised for 20 ft or 40 ft container shipments. Common Incoterms for Chinese carbide exports are FOB Shanghai/Ningbo, CIF, and CFR, with sea freight being the dominant mode for non-urgent tooling orders and air freight used for small, high-value indexable insert reorders. Chinese cemented carbide production is concentrated in Zhuzhou (Hunan), Zigong (Sichuan), and Ganzhou (Jiangxi), with Guizhou-based producers such as this Zunyi supplier also active in block/bar stock and wear parts.

Sourcing from Zunyi Zhongbo Cemented Carbide Co., Ltd - Buyer Guidance

For buyers evaluating Zunyi Zhongbo Cemented Carbide Co., Ltd, the key documents and specifications to request are: the exact ISO 513 grade classification for each insert type (e.g. P10-P30 for steel turning, K10-K20 for cast iron), cobalt content percentage, WC grain size in micrometres, hardness in HRA, transverse rupture strength in N/mm², and any coating specification (TiN, TiAlN, CVD/PVD). For the YG8/YG15 block, bar and plate stock under HS 8209.00, request dimensional tolerances (typically ±0.5 mm on thickness for stock), surface finish, and a mill test certificate. Samples should be requested before bulk orders, particularly for indexable inserts where geometry and edge preparation strongly affect tool life. Before placing an order, buyers should confirm minimum order quantities (MOQs), which for carbide inserts and tips are commonly 100-500 pieces per SKU and 10-50 kg for block/bar stock, and clarify packaging (inner plastic boxes vs. blister packs), lead times (typically 15-30 days for stock items and 30-45 days for custom grades), and whether the supplier can provide OEM/ODM services for private-label packaging. Standard payment terms in this segment are usually 30% T/T deposit with balance against copy of B/L, or L/C at sight for larger container orders. Independent third-party inspection (SGS, BV, TUV) of dimensions, hardness and coating thickness is advisable for first orders, and buyers should verify that any stated ISO 9001 certification is current and covers the specific production site in Zunyi.
