Import Carbide Threading Insert — Buy in Bulk from Supplier in China

The carbide threading insert from Zhejiang Jetstar Cemented Carbide Co., Ltd. is a precision tool designed for threading operations in metalworking. It features a high wear resistance geometry engineered for accurate thread formation in materials such as steel, stainless steel, and cast iron. The insert’s carbide composition ensures extended tool life under high-speed machining conditions, reducing downtime and replacement costs.

Manufactured from fine-grained tungsten carbide, the insert typically achieves a hardness of 1600-1900 HV, with a standard coating of titanium nitride or aluminum oxide to enhance surface durability. It is compatible with standard threading tool holders and supports internal and external threading applications. Industry standards for such inserts include ISO 1832 for grade classification and ANSI B1.20.1 for thread tolerance compliance, ensuring consistency across production batches.

This insert is used in automotive, aerospace, and general manufacturing for high-volume threading tasks where precision and repeatability are critical. Buyers often source it in bulk for CNC lathes and Swiss-type machines, with typical packaging in plastic cases or blister packs to prevent edge damage. Confirm the exact thread pitch range, coating type, and compatible holder series with the supplier before ordering.
