About Zhuzhou Yujie Cemented Carbide Co., Ltd. - Drilling Machines & Tools Supplier in China

Based in China, Zhuzhou Yujie Cemented Carbide Co., Ltd. currently lists nine distinct cemented‑carbide products. The catalogue includes die‑grinder bits, solid carbide end mills, woodworking knives, drill bits for aluminium, round saw‑blade burrs, polished carbide spheres, carbide rods, CNMG indexable inserts and general carbide burrs. All items fall under the broader categories of Drilling Machines & Tools and Tools & Instruments, reflecting a focus on precision cutting components used in metalworking and machining operations.

The nine products are identified by their functional type rather than by specific dimensions, allowing buyers to match them to standard machining requirements. Each product is described using the term “tungsten carbide,” indicating a cemented carbide matrix typically composed of tungsten carbide particles bonded with cobalt. The supplier’s catalogue does not provide HS‑code numbers, but the items belong to the HS‑code families that cover cutting tools of base metal and carbide‑based tool components.

The supplier’s trust tier is listed as “harbor,” which signals a moderate level of verification within the platform. No additional corporate claims such as founding year, employee count, or revenue are supplied. All information presented here is derived directly from the provided facts and standard industry knowledge for cemented‑carbide tooling.

Product Range and Specialties of Zhuzhou Yujie Cemented Carbide Co., Ltd.

The product set covers common cemented‑carbide tool forms: die‑grinder burrs for fine surface finishing, end mills for slotting and contouring, woodworking knives for high‑speed wood removal, solid drill bits optimized for aluminium machining, round saw‑blade burrs for circular cuts, spherical carbide balls used in precision grinding, rods that serve as raw blanks for custom tooling, CNMG indexable inserts for interchangeable turning tools, and general burrs for deburring and shaping. In the carbide industry, these items are typically produced with WC‑Co compositions ranging from 80 % to 92 % tungsten carbide and cobalt binders from 8 % to 12 %. Hardness values commonly fall between 1 500 and 2 000 HV, and tolerances are often held within ±0.01 mm for end‑mill diameters and ±0.02 mm for drill‑bit shank dimensions. Standard specifications such as ISO 13399 for cutter geometry and ISO 9001‑based quality management are frequently referenced by manufacturers of similar tools.

Trade and Export Information - Zhuzhou Yujie Cemented Carbide Co., Ltd.

China is one of the world’s largest exporters of cemented‑carbide tooling, supplying automotive, aerospace, and general manufacturing sectors across Europe, North America and Southeast Asia. Products like the ones listed by Zhuzhou Yujie typically fall under HS Chapter 82 (e.g., 8207  -  tools of base metal, steel, iron or other alloys, of a kind used for cutting), and Chapter 84 (e.g., 8465  -  machine tools for working of metal or other materials). Importers often require certifications such as ISO 9001 for quality management, ISO 14001 for environmental compliance, and test reports confirming hardness, grain size and cobalt content. Shipping is usually arranged in standard 20‑ft or 40‑ft containers with wooden crate or bulk bag packaging, and Incoterms such as FOB Shanghai or CIF destination port are common for these high‑value, low‑volume items.

Sourcing from Zhuzhou Yujie Cemented Carbide Co., Ltd. - Buyer Guidance

When evaluating Zhuzhou Yujie’s carbide tools, request a material test report that details WC‑Co ratio, grain size (typically 0.5 - 2 µm for high‑grade tools) and measured Rockwell or Vickers hardness. Verify that the supplier can provide ISO‑9001 certification or equivalent documentation, as this is a standard requirement for buyers in regulated industries. Samples of representative items - such as a 6 mm end‑mill or a 3 mm drilling bit - allow verification of dimensional tolerance and surface finish before placing larger orders. Typical minimum order quantities for individual tool types range from a single piece for prototypes to several hundred pieces for production runs, with lead times of 2 - 4 weeks depending on the item’s complexity and required heat‑treatment.

What types of cemented‑carbide tools does Zhuzhou Yujie offer?

The catalogue lists die‑grinder burrs, solid carbide end mills, woodworking knives, aluminium‑specific drill bits, round saw‑blade burrs, polished carbide spheres, carbide rods, CNMG indexable inserts and general carbide burrs.

Are HS‑code numbers available for these products?

Specific HS codes are not provided in the catalogue, but the items belong to the HS‑code families for cutting tools (e.g., 8207) and machine‑tool components (e.g., 8465) that are commonly used for cemented‑carbide products.

Which quality certifications should a buyer request?

Buyers should ask for ISO 9001 quality‑management certification, ISO 14001 environmental certification, and a material test report showing WC‑Co composition and hardness values.

What is a typical minimum order quantity (MOQ) for these tools?

MOQs vary by product; prototype‑size orders can be as low as one piece, while bulk orders usually start at a few hundred pieces per item.

What lead time can be expected for a standard order?

Lead times are generally 2 to 4 weeks after order confirmation, depending on the specific tool type and any required post‑processing such as heat treatment.

How are the products packaged for export?

Cemented‑carbide tools are commonly packed in sealed cardboard boxes, bulk bags or wooden crates, with protective foam inserts to prevent damage during transit.

Which regions commonly import Chinese cemented‑carbide tools?

Key import markets include the United States, Germany, Japan, South Korea and Brazil, where the automotive, aerospace and general manufacturing sectors consume large volumes of carbide tooling.

What documentation is needed to clear customs for these items?

Customs typically require a commercial invoice, packing list, certificate of origin, and any applicable safety data sheets or material test reports that reference the HS‑code classification.
