What is a O Flute bit? *Or sometimes this type of bit is called a Single Flute bit*

Our “O” flute tools are manufactured from solid carbide tool material in straight and spiral configuration. The upcut, or right hand spiral is most readily utilized because of the need to evacuate chip in an upward direction in flat sheet or block applications. Upward movement of chips avoids welding, which is a common problem in the machining of plastic. With a high rake angle and relatively low helix, O-flute cutters manage to cut acrylic, polycarbonate, ABS, PVC at very high chip loads without raising a burr or fracturing the edges of the surface. All of this while leaving a really clean surface finish. “O” flutes also work incredibly well in wood and aluminum with effortless chip removal!

Zoe B. ★★★★★

Took a chance on this for cutting 1/4" acrylic on my CNC and the single flute clears chips so much better than the two-flute bits I was using. The 1/8" cutting length is short, so it's really only good for sheet up to about that thickness, but the finish on the edges came out almost polished.

Charlotte ★★★★★

Bought this to cut acrylic for some back-lit control panels and the single flute really clears chips instead of gumming up the cut. The 11/64" shank fits my standard collet, no adapter needed. Six and a half inches of reach lets me get into deep pockets without the collet rubbing.

Madison ★★★★★

The 1/8" cut length is perfect for the 1/4" Corian I've been trimming, and the single flute clears chips way better than the two-flute bits I used before. Six and a half inches of reach lets me get deep into the sign foam without the shank rubbing.
