Abstract

See full text

The present invention provides rotatable cutting tools having washers with changing thicknesses. One side of the washer has a tapered surface that increases the thickness of the washer from the inner radius towards the outer radius, resulting in a thicker portion at the outer edge of the washer. The rotatable cutting tool may also have a bit with a tapered surface. The tapered surface of the bit may be structured and arranged to engage with the tapered surface of the washer. The rotatable cutting tool may also include a holder such that the assembled rotatable cutting tool includes the washer between the bit and the holder with the bit inserted into the holder and washer.
