Characterized by high hardness, high wear resistance and good weldability, carbide strip is served as a tool blank to cut solid wood, density board, gray cast iron, non-ferrous metals, chilled cast iron, hardened steel, PCB and brake material in the industries of ceramics, printing machinery, forestry, rubber, plastics, textile industry, cigarette machinery, packaging materials, cables, shipbuilding, metallurgical machinery, electronics, leather etc. Appropriate grade must be selected to cut different materials in order to achieve the best cutting performance. However, ZZSINO’s SK30L is a popular and universal grade with wide applications, cutting both metals and non-metals. Besides properties, strip dimension is also important when choosing a strip, especially straightness. A strip with bad straightness will result in unnecessary grinding even insufficient grinding.
