从China供应商批发进口330 Cemented Rods With 3 Helical Coolant Holes — FOB条款

These are tungsten carbide cemented rods designed with three helical coolant holes, supplied as blanks for precision cutting tool production. The rods follow the D*d*TK*LB type specification, with a standard length of 330 mm or 310 mm and diameters ranging from 6.3 mm to 20.3 mm. The helical angle is typically 30 degrees, with optional angles of 15, 40, or 45 degrees to suit different machining applications.

The material composition is cemented carbide (WC+Co), available in grades K05 to K40, with fine or medium grain sizes. Hardness ranges from 87.6 to 94 HRA, and transverse rupture strength (T.R.S) spans 3000 to 4200 MPa. The surface finish can be supplied as blank or ground, depending on the buyer’s requirements for further machining. Helical coolant channels are engineered to improve chip evacuation and extend tool life in high-speed operations.

These rods are primarily used to manufacture twist drills, end mills, and specialized cutting tools for industries like aerospace, automotive, and precision engineering. Buyers typically source them for further machining into custom tools, where the helical design enhances coolant flow and thermal stability. Trade terms such as MOQ, packaging, and lead times should be confirmed directly with the supplier, as these are not specified in the listing.

Zhuzhou Better Tungsten Carbide Co., Ltd is based in the Tianyuan District of Zhuzhou City, Hunan Province, China. The company operates from Bv 12-305, Da Han Hui Pu Industrial Park, No. 1318, Huanghe North Road, a location known for its concentration of carbide and hard metal manufacturers.

The supplier’s profile indicates a Harbor trust tier, though no response rate or average response time data is currently available. The listing provides detailed technical specifications for its carbide rods but does not include additional information about certifications, production capacity, or client history. Buyers should verify operational details directly with the supplier.
