330 Cemented Rods with 3 Helical Coolant Holes
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.

Sourcing 330 Cemented Rods with 3 Helical Coolant Holes from Zhuzhou Better Tungsten Carbide Co., Ltd - China Import Guide
Before ordering, verify the helical angle and coolant hole configuration to ensure compatibility with your machining setup. Confirm the grade (K05 to K40) and grain size, as these directly impact tool performance and longevity. Request material test reports (MTRs) to validate the hardness and T.R.S values.
Discuss logistics details such as packaging, which may include wooden cases or plastic-lined cartons to prevent damage during transit. Clarify Incoterms (e.g., FOB or CIF) and payment terms, as these are not specified in the listing. Lead times may vary based on customization requirements, so confirm production schedules upfront.
Inspect the rods upon arrival for dimensional accuracy, surface finish, and absence of defects. Use calipers and micrometers to verify diameter and length tolerances. For critical applications, conduct a trial run to assess chip evacuation and coolant flow before full-scale production.
