Two flute O-flute straight bits provide a finer surface finish compared to single flute options by increasing the number of cutting contacts per revolution, while still maintaining the open flute geometry needed to prevent heat buildup in plastic cutting. These bits are a strong choice for applications where edge finish quality on acrylic, polycarbonate, PVC, and other engineered plastics is a priority and feed rates are moderate. The two-flute design reduces chip load per flute while keeping the cut zone clear of recutting.
