ABSTRACT:
A chip breaking device for annular cutters has a comb-shaped member fixed to the front wall of a boring machine. The comb-shaped member includes a stem extending in parallel with the annular cutter rotated by the boring machine and three or more elongated chip breaking elements extending perpendicularly from the stem and into proximity to the outer periphery of the annular cutter. Chips formed by the annular cutter hit against the chip breaking elements and their tip portions are caught by the elements. Then, intermediate portions pass through the spacings between the adjacent chip breaking elements. Thereafter the chips are pulled and broken into pieces.
