ABSTRACT:
A spiral four fluted rotary carbide cutter has a one directional helix throughout much of its length, and a reverse directional helix adjacent the cutting end. Opposite lands, between the flutes, have square cornered axially aligned and equally spaced notches; with adjacent lands having the notches intermediately located with respect to each other. All of the notches are at an angle of about 20 degrees with respect to a line perpendicular to the axis of the cutter to in combination provide a cutter for Kevlar containing composite panels.
