High precision : The meticuloes manufacturing porcess allowed excellent axial runout of side face and roughness, as well as roughness of machined surface to improve dramatically in contrast to original high speed steel products. High Efficiency : The high-speed cutting varied materials such as normal steel and cast iron saves time in The manufacturing process. More long-life : In contrast to high soeed steel products, solid carbide products are far more resistant to wear. This means you will replace the tools at less frequency. and at lower cost.
