PreciseBits MP103F/MP108F OFlute

Overview

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.

As micro-manufacturing has exploded across widely diverse market segments, there has been an increasing demand for O-flute cutters with smaller diameters, especially cutters in the micro range below 1/16 in.. All that was needed was to determine the scaling factors that would allow O-flute microtools to be economically fabricated while maintaining the rigidity to ensure low bit deflection and excellent edge quality under high chiploads.

The high rake, modified "O" style flute is optimized for cutting thermoplastics and the 1-Flute design allows efficient swarf removal under high chiploads. Out optimized cutting edge geometry designed for burr-free, fractureless profile cutting.
