O-flute Single Flute Thermoplastic Cutters (MP104) - 1/4 in. (0.2500") shank

The "O" flute geometry introduced more than a decade ago is one of the most efficient flute designs for cutting thermoplastics that has yet been invented. With a high rake angle and relatively low helix, O-flute cutters manage to cut acrylic, polycarbonate, ABS, PVC and a host of other sheet polymers at very high chiploads without raising a burr or fracturing the edges of the kerf. All of this while leaving a remarkably clean surface finish. The real surprise is that this revolutionary geometry also works incredibly well in wood and aluminum.
