The C8 series are great for applications that require multiple size tools all with common 1/4" diameter shanks. The larger shank also helps with rigidity and improves performance. The C8 series are downshear tools with high positive rake angles for non-ferrous materials like aluminum, brass, copper, and wood. This tool is a standard length 2 flute downshear tool. This helps to put downward force on the material keeping laminated materials or sensitive materials from chipping on the top edge. This series is also made from the most wear resistant carbide we use.
