• For CNC milling and routing on aluminum and plastics where a clean top surface edge of material is required
• Premium C3 micro-grain solid tungsten carbide for a high-performance industrial quality tool
• For use on CNC, table mount and handheld routers
• Polished to a mirror finish from a solid carbide rod for precision & accuracy

O flute spiral router bits are designed to produce clean cuts in acrylic, HDPE, UHMW and other plastics. The spiral downcut geometry shears in a downward direction leaving a smooth top surface finish. O flute bits have a larger cullet than standard spiral bits which allow for larger chips. This alleviates overheating which can cause the material to melt and create rough or deformed cuts.
