Abstract
A milling cutter tool for cleanly and smoothly cutting honeycomb core material is disclosed. The cutter tool includes a circular saw blade sharpened to a knife edge. A bevel extends from the upper surface towards the sharp peripheral edge. A plurality of cutter bodies extend vertically above the circular saw blade. The cutter bodies include a plurality of teeth generally parallel to each other and extending vertically with respect to each other. The teeth include a piercing point and sharp cutting edges extending at a clearance angle from the piercing point. A flat surface extends between the teeth. The circular saw blade having a sharp bevel cutting edge provides a clean cut of the honeycomb core material at the surface to be cut. The sharp points of the cutting edges pierce the honeycomb material, dig into it and slice it. The cutting edges further slice and cut the dross honeycomb core material as it is separated from the surface being cut. A clean, smooth surface is left to which a panel may be bonded.
