Tungsten Carbide Copper Milling Inserts, also known as scalping cutter for copper and copper alloy. Our cutting blade showcases exceptional material removal performance, facilitating efficient and rapid milling of copper surfaces to elevate processing efficiency. Tailored for applications demanding precision, it excels in ensuring post-processing smoothness and accuracy on copper surfaces. With remarkable wear-resistant properties, this blade significantly extends its lifespan, reducing the need for frequent replacements and thereby enhancing overall production efficiency. Designed with a focus on minimizing cutting resistance, it effectively reduces resistance during cutting, limits heat accumulation in the machining process, contributing to an extended tool and workpiece lifespan. In addition, our specialized tool is designed for the removal of oxidized scales and defects from the surfaces of copper and copper alloy strips after undergoing hot mill processes. This tool is dedicated to continuous roughing of both up and down sides of thin copper and copper alloy boards rolled in a hot situation. Ideal for applications in electronic equipment, such as connector terminals or lead frame materials, our scalping cutter is engineered to handle even high-strength and difficult-to-cut copper alloys. With high-strength cemented carbide and excellent brazing technology, it not only scalps the surface effectively but also contributes to significant productivity improvements for our customers.
