O-flute Corner-radius 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.

Manufactured in the USA, every tool is:

  • 100% measured / optically inspected to insure that EVERY tool meets, or exceeds, our published specifications
  • available with depth rings precisely positioned to ±0.0015 in. (0.038mm), virtually eliminating the need for resetting Z-axis zero between tool changes (with bits of same overall length)
  • made from premium grade submicrograin tungsten carbide (HRa 92, HRc 80)

One of the recurring complaints about O-flute tools, is that the high chipload results in "swirl marks" in the bottoms of pockets. For most applications, this is not a problem but, in the case of side-lit transparent acrylic panels, these artifacts can severely impact the quality of the engraved image. Our radiused O-flute tools virtually eliminate these cutting marks, yielding a smooth, near specular bottom finish.
